Description

Method and device for adding chemical production raw materials and chemical production system

Technical Field

The present disclosure relates generally to the field of chemical production, and more particularly, to a method, apparatus, and chemical production system for chemical production raw material addition.

Background

Chemical production facilities, including thermoplastic polyurethane production facilities, are typically configured with solid feeders to provide solid raw materials, including reactants, catalysts, and/or other adjuvants, to the chemical production system. The solid feeder is easy to generate flow fluctuation under low loading capacity so as to influence the quality of chemical products, so that excessive solid production raw materials are usually provided for the solid feeder when chemical production is carried out, the produced chemical products accord with quality standards, meanwhile, equipment is effectively maintained, and the solid feeder can remain excessive solid powder raw materials when a production order is finished.

The same chemical production equipment can be used for producing different chemical products. Different production orders often have different raw material property requirements for the raw materials used due to the different quality or use of the chemical products produced. For example, a production order for a high quality chemical product requires the use of high quality production materials. The bonded production stock may be used to produce production orders for foreign customers (i.e., bonded orders), but not for domestic customers (i.e., non-bonded orders), and so forth. In this case, if the chemical production equipment receives a new production order, it is necessary to manually take out the residual solid production raw material of the previous production order in the solid feeder, and clean the solid feeder before the corresponding solid production raw material is added to perform the order production of the received production order.

Since the solid powder raw material charging area is usually an explosion-proof area, dust emission is caused by taking out the solid raw material, and thus dust explosion risks exist. In addition, the solid materials to be taken out can have treatment management risks, and the quality of the raw materials can be affected by damp agglomeration and the like. In addition, as the chemical production equipment needs to continuously execute production orders for production, the production stop can be caused by taking out the solid production raw materials and cleaning the solid feeders, so that the production capacity and the production benefit of the chemical production are reduced.

Unless the context clearly indicates otherwise, the definition of a term is consistent throughout this specification.

When chemical production is carried out, if chemical production equipment receives a new production order, the residual solid production raw materials of the previous production order in the solid feeder of the chemical equipment are manually taken out, and the solid feeder is cleaned and then the corresponding solid production raw materials can be added to carry out order production of the received production order. Since the solid powder raw material charging area is usually an explosion-proof area, dust emission is caused by taking out the solid raw material, and thus dust explosion risks exist. In addition, the solid materials to be taken out can have treatment management risks, and the quality of the raw materials can be affected by damp agglomeration and the like. In addition, as the chemical production equipment needs to continuously execute production orders for production, the production stop can be caused by taking out the solid production raw materials and cleaning the solid feeders, so that the production capacity and the production benefit of the chemical production are reduced.

In view of this, embodiments of the present disclosure provide a method and apparatus for chemical production raw material addition. By utilizing the method and the device, after receiving a new production order, the raw material delay of the residual production raw material of the previous production order on the new production order is determined based on the raw material attribute of the production raw material used by the new production order, the residual raw material quantity of the residual production raw material of the previous production order is measured through the weight measurement equipment deployed at the solid feeder under the condition of the raw material delay, and the production raw material adding scheme aiming at the new production order is determined based on the residual production raw material, so that the solid production raw material taking out and the solid feeder cleaning are not required to be executed on the solid feeder, thereby reducing the production risk in the chemical production process and improving the production capacity and the production benefit of chemical production.

A method, an apparatus for chemical production raw material addition, and a chemical production system according to embodiments of the present specification are described below with reference to the accompanying drawings.

Fig. 1 shows an example schematic diagram of a chemical production system 100 according to an embodiment of the present disclosure.

As shown in fig. 1, the chemical production system 100 includes a chemical production apparatus 110, a raw material adding apparatus 120, a raw material management apparatus 130, a raw material adding control device 140, and a chemical production management apparatus (MES, manufacturing Execution System) 150. The chemical production facility 110, the raw material addition facility 120, the raw material management facility 130, the raw material addition control device 140, and the chemical production management facility 150 may communicate with each other through the network 160 for data transmission. In some embodiments, network 160 may be any one or more of a wired network or a wireless network. Examples of network 160 may include, but are not limited to, a cable network, a fiber optic network, a telecommunications network, an in-enterprise network, the internet, a Local Area Network (LAN), a Wide Area Network (WAN), a Wireless Local Area Network (WLAN), a Metropolitan Area Network (MAN), a Public Switched Telephone Network (PSTN), a bluetooth network, a ZigBee network, a Near Field Communication (NFC), an in-device bus, an in-device line, and the like, or any combination thereof. In some embodiments, the process feedstock addition control device 140 may be in direct communication with some or all of the components in the chemical production facility 110, the process feedstock addition facility 120, the process feedstock management facility 130, and the chemical production management facility 150 without the network 160.

The chemical production facility 110 is configured to perform chemical production using production materials meeting production order requirements after receiving a production order. The chemical production facility 110 has a solids feeder disposed thereon. The process feed addition apparatus 120 is used to add process feed to the solid feeders of the chemical production apparatus 110 according to a process feed addition scheme. For example, the process raw material adding apparatus 120 may pick up the process raw material from the process raw material storage apparatus according to the process raw material adding scheme determined by the process raw material adding control device 140, and add the picked-up process raw material to the solid feeder of the chemical production apparatus 110. In some embodiments, for each production order being produced, identification information for the production order may be provided on the solid feeder, e.g., a two-dimensional code for identifying the production order may be printed on the solid feeder.

The production raw material management apparatus 130 is for performing inventory management for production raw materials. For example, the production raw material management apparatus 130 may save and maintain production raw material inventory information of production raw materials, such as an inventory amount and a raw material attribute of each production raw material.

The chemical production management device 150 may manage chemical production orders. For example, the chemical production management device 150 may store raw material property requirements for chemical production orders, save and maintain production raw material consumption information, and the like. In addition, the chemical production management apparatus 150 may also be used to manage the production process of the chemical production apparatus 110, for example, to manage and control the production process, production sequencing, chemical raw material supply, etc. of the chemical production apparatus 110.

The raw material addition control means 140 is for, after receiving a production order, determining a raw material addition scheme for the received production order, and controlling the raw material addition apparatus 120 to add raw material to the solid feeder of the chemical production apparatus 110 according to the determined raw material addition scheme. Further, the raw material addition control device 140 may also modify the raw material inventory information at the raw material management apparatus 130 according to the determined raw material addition scheme.

Fig. 2 illustrates an example flow chart of a method 200 for chemical production raw material addition according to an embodiment of this specification. The method 200 for chemical raw material addition is performed by the raw material addition control device 140.

As shown in fig. 2, at 210, in response to a first chemical production order to be executed, it is determined whether the remaining production materials in the solid feeder have a material-extending property based on the material property requirements of the first chemical production order and the material properties of the remaining production materials of the last chemical production order in the solid feeder of the chemical production facility. In this disclosure, the term "raw material availability" means that the remaining production raw material remaining from the previous chemical production order may continue to be used to produce a new chemical production order. Depending on the product requirements of the chemical product produced by the chemical production order, the chemical production order has specific requirements for the production raw materials used for producing the chemical product, for example, the production raw materials used are required to have specified raw material property requirements, for example, quality requirements, order property requirements, and the like.

The manufacturing materials used in chemical production may have one or more material properties. The feedstock attributes may include, for example, purpose attributes, purpose association attributes, and other attributes. For example, the term "usage attribute" is used to indicate what usage of production raw materials can be used for production, such as for production of which chemical products/which types of chemical production orders. Examples of usage attributes may include, for example, product attributes, order attributes, and the like. Product attributes are used to indicate which products the feedstock is suitable for use in producing. Product attributes may be represented using a product set or product column. For example, the product attributes may be "thermoplastic polyurethane product A/B", "thermoplastic polyurethane product C/D/E", "catalyst F", "stabilizer G", and the like. The order attribute is used to indicate which type of chemical production order the material is suitable for use in production. Chemical production orders may include, for example, bonded orders and non-bonded orders. The bonded order refers to a chemical production order requiring production using bonded materials, and the non-bonded order refers to a chemical production order requiring production using non-bonded materials. The term "bonded material" refers to the imported material which is not subjected to tax collection (including value-added tax, tariff, etc.) and the finished product of bonded export, and the other materials (tax collection import and domestic purchase material) are all "non-bonded materials". Note that the order attribute is a configurable usage attribute. The configurable usage attribute may be used to make usage attribute adjustments if certain conditions are met. For example, for the order attribute "bonded order", if the production raw material is re-tax-reported, the order attribute may be adjusted from "bonded order" to "non-bonded order". Further, optionally, the usage attributes may also include, for example, specified product attributes. The term "specified product attributes" is used to indicate which chemical products a manufacturing feedstock is specified to use to produce. For example, as for the production raw material a, it may be applicable to production of chemical products a/B/C, but in production practice, the production raw material a is designated for production of chemical products a and B, and the "designated product attribute" of the production raw material a is "product a/B". "specific product attributes" are also configurable usage attributes. For example, with the above-described production raw material a, the "specified product attribute" thereof may be configured as "product B/C" under certain conditions. The usage-related attribute is used to indicate a raw material attribute associated with the usage of the production raw material. The use-related properties may have a decisive influence on the use of the production raw material. Examples of user-associated attributes may include, for example, but are not limited to: quality, purity, moisture content, acid number, bulk density, chromaticity, etc. The user-associated attribute is an inherent raw material attribute of the production raw material, and cannot be configured or modified. Other attributes may include, for example, place of origin, lot number, appearance, etc.

In the example of fig. 3, each production feedstock may have a production feedstock identification, a usage attribute, a user-associated attribute, and other attributes. The production material identifier may be, for example, a production material number, a production material code, a production material name, or the like, for uniquely identifying the production material. The usage attributes may include, for example, product attributes, order attributes, specified product attributes, and the like. The usage-related attributes may include, for example, quality, moisture content, and the like. Wherein the order attribute and the specified product attribute are configurable usage attributes.

In some embodiments, the solids feeder is provided with identification information for the production order. In this case, the raw material attribute information of the remaining raw materials for the previous chemical production order may be acquired from the chemical production management apparatus by scanning order identification information of the previous chemical production order on the solid feeder.

Fig. 4 shows an example flowchart of a raw material availability determination process 400 according to an embodiment of the present disclosure.

As shown in fig. 4, at 410, the usage attributes of the production materials required for the first chemical production order and the remaining production materials of the last chemical production order are compared, and at 420, it is determined whether the usage attributes of the production materials required for the first chemical production order and the remaining production materials of the last chemical production order match. Here, the term "usage attribute matching of the production raw material" is used to indicate the interchangeable use of the production raw material. For two production materials, if used interchangeably, the usage attributes of the two production materials match.

If it is determined that the usage attributes of the production materials required for the first chemical production order and the remaining production materials of the last chemical production order do not match, then at 430, it is determined that the remaining production materials of the last chemical production order do not have a material utility.

If it is determined that the usage attributes of the production materials required for the first chemical production order and the remaining production materials of the previous chemical production order match, then at 440, based on the usage-related attributes of the production materials, downward compatibility of the remaining production materials with respect to the production materials required for the first chemical production order is determined, and at 450, a determination is made as to whether the remaining production materials have downward compatibility with respect to the production materials required for the first chemical production order. Here, the term "downward compatibility" is used to indicate that a higher-level feedstock property is compatible with a lower-level feedstock property. For example, for the raw material attribute "quality", "high quality" raw materials may be downward compatible with "medium quality" or "low quality" raw materials. In other words, high quality production materials can be used to produce chemical production orders that have lower requirements on the quality of the materials. For example, a production feedstock with a higher purity value may be downward compatible with a production feedstock with a lower purity value, etc., for the feedstock attribute "purity".

If it is determined that the remaining production materials do not have downward compatibility with respect to the production materials required for the first chemical production order, then at 430, it is determined that the remaining production materials of the last chemical production order do not have a material utility. If it is determined that the remaining production materials have downward compatibility with respect to the production materials required for the first chemical production order, then at 460, it is determined that the remaining production materials of the last chemical production order have material utility.

Returning to fig. 2, in response to determining that the feedstock is not available for use, at 230, the remaining production feedstock is removed from the solids feeder, the solids feeder is cleaned, and after the solids feeder cleaning is completed, the production feedstock addition device is controlled to perform production feedstock addition in accordance with the production feedstock required by the first chemical production order.

In response to determining to have feedstock extensibility, a remaining feedstock amount of a remaining production feedstock in the solids feeder is determined via a weight measurement device disposed at the solids feeder, at 240. The weight measuring device may be implemented using any weight measuring means suitable in the art. For example, after determining that there is a feedstock delay, the feedstock addition control device may issue an indication to a weight measurement device disposed at the solids feeder to determine a remaining feedstock amount of the remaining feedstock in the solids feeder. After the weight measuring device determines the remaining raw material amount of the remaining raw material for production, the remaining raw material amount of the remaining raw material for production is supplied to the raw material addition control device.

At 250, a process feed addition recipe for the first chemical process order is determined based on the remaining feed amount of the remaining process feed, the process feed requirements of the first chemical process order, and the process feed inventory information. The determined production raw material addition scheme includes raw material compositions of the production raw materials to be added and raw material amounts of various composition raw materials.

For example, the production raw material addition control means may acquire production raw material inventory information from the production raw material management device, the acquired production raw material inventory information including inventory amount information and raw material attribute information of the production raw material. Fig. 5 shows an example schematic diagram of production raw material inventory information according to an embodiment of the present specification.

After the production raw material inventory information is acquired, a production raw material addition scheme for the first chemical production order is determined based on the remaining raw material amount of the remaining production raw materials, the production raw material requirements of the first chemical production order, and the production raw material inventory information. For example, the production raw material addition amount may be obtained by subtracting the remaining raw material amount of the remaining production raw material from the production raw material demand amount of the first chemical production order. Then, a target production raw material having a raw material attribute satisfying the production raw material requirement of the first chemical production order is queried in the production raw material inventory information, and a production raw material addition scheme for the first chemical production order is determined based on the inventory amount of the target production raw material satisfying the production raw material requirement and the addition amount of the production raw material, and the determined production raw material addition scheme may include, for example, the raw material composition of the production raw material to be added and the raw material amounts of the various constituent raw materials. For example, if the target production raw material includes only one target production raw material, the additive production raw material is composed of only one production raw material, and the raw material amount of the production raw material is the production raw material additive amount. If the target production raw materials include at least two target production raw materials, one or more target production raw materials may be selected to constitute an additive production raw material, and the raw material amount of each target production raw material is a part of the production raw material additive amount. In this case, the selection of the constituent production raw materials and the raw material amounts of the constituent production raw materials may be determined based on the degree of matching of the raw material properties of the target production raw materials with the production raw material requirements of the first chemical production order, the stock amounts of the respective target production raw materials. Alternatively, in the production raw material management apparatus, a minimum stock quantity threshold may be set for each production raw material. Accordingly, the selection of the constituent production raw materials and the raw material amounts of the constituent production raw materials may be determined based on the degree of matching of the raw material properties of the target production raw materials with the production raw material requirements of the first chemical production order, the stock amounts of the respective target production raw materials, and the minimum stock amount threshold.

After the process feed addition schedule for the first chemical production order is determined as above, the process feed addition apparatus is controlled to add process feed to the solids feeder according to the process feed addition schedule at 260.

Optionally, after determining the process material addition scheme for the first chemical production order, the process material inventory information at the process material management device may also be modified according to the process material addition scheme at 270. For example, the stock amounts of the corresponding production raw materials in the production raw material stock information may be modified according to the raw material composition of the production raw materials to be added in the production raw material addition scheme and the raw material amounts of the various constituent raw materials.

In some embodiments, the usage attributes include configurable usage attributes, and the determined production raw material addition scheme may further include raw material attribute information and a remaining raw material amount of the remaining production raw materials. In this case, when modifying the production raw material inventory information at the production raw material management apparatus, the configurable raw material property of the production raw material may be modified in addition to the stock quantity of the production raw material. The configurable feed properties include at least configurable usage properties.

Fig. 6 shows an example flowchart of a process 600 for manufacturing stock inventory information modification according to an embodiment of the present description.

As shown in fig. 6, at 610, the stock amounts of the corresponding production raw materials in the production raw material stock information are modified according to the raw material composition of the production raw materials to be added in the production raw material addition scheme and the raw material amounts of the various constituent raw materials.

Then, according to the raw material attribute information and the residual raw material amount of the residual raw materials in the raw material adding scheme, part or all of configurable application attributes of the corresponding raw materials in the raw material inventory information after the inventory amount modification are modified.

For example, at 620, the inventory information of the production raw materials modified by the inventory level is queried for a first target production raw material having a raw material attribute that matches the raw material attribute of the remaining production raw materials. For example, raw material property matches between the remaining raw materials of production and the first target raw materials of production may be determined based on the usage-related properties and the non-configurable usage properties of the raw materials of production.

At 630, the queried partial or all configurable usage attribute of the partial production raw material in the first target production raw material is modified to the corresponding configurable usage attribute of the remaining production raw material, the raw material amount of the partial production raw material being equal to the remaining raw material amount of the corresponding remaining production raw material. For example, assuming that the order attribute of the remaining production materials is "bonded order" and the order attribute of the first target production materials is "non-bonded order", the order attribute of a part of the first target production materials is modified to "bonded order". Further, if the specified product attribute of the remaining production raw materials is "product a/B", the specified product attribute of the first target production raw material is "product B/C", and the product attribute of the first target production raw material is "product a/B/C", then the specified product attribute of a part of the first target production raw materials is modified to "product a/B". In some embodiments, the modified configurable usage attribute may be, for example, a configurable usage attribute having a modified correspondence. The term "modification correspondence" means that the property of the raw material can be correspondingly modified, and that such property modification does not result in the production raw material not being able to continue to be scheduled for use in the subsequent product production process. For example, a corresponding modification between the order attributes "bonded order" and "non-bonded order", a corresponding modification between the specified product attributes, and so forth.

In some embodiments, the queried first target production feedstock may include at least two production feedstocks. In this case, a raw material attribute information modification scheme for the production raw material inventory information, which includes the production raw material identification, the raw material amount, and the configurable raw material attribute modification manner of the various production raw materials to be modified, may also be determined based on the raw material attribute and the remaining raw material amount of the remaining production raw materials, and the raw material attribute and the raw material inventory amount of the first target production raw materials. Then, production raw material inventory information modification for the first target production raw material is performed according to the obtained raw material attribute information modification scheme.

Fig. 7 shows an example schematic diagram of modified production feedstock inventory information according to an embodiment of the present description. In the example of fig. 7, for a manufacturing feedstock identified as 0076, the inventory is 100 prior to execution of the first manufacturing order. In the obtained production raw material addition scheme, the usage amount of the production raw material is 20, and in the raw material attribute information modification scheme, it is necessary to modify the "order attribute" of the part of the production raw material whose raw material amount is 35 from the "non-bonded order" to the "bonded order" for the production raw material whose production raw material amount is 0076, thereby obtaining the production raw material inventory information as shown in fig. 7.

According to the above-mentioned production raw material addition scheme, after receiving a new production order, the raw material extensibility of the residual production raw material of the previous production order on the new production order is determined based on the raw material attribute of the production raw material used by the new production order, and the residual raw material amount of the residual production raw material of the previous production order is measured via the weight measurement equipment deployed at the solid feeder under the condition of the raw material extensibility, and the production raw material addition scheme for the new production order is determined based on the residual production raw material, so that the solid production raw material taking out and the solid feeder cleaning are not required to be executed on the solid feeder, thereby reducing the production risk in the chemical production process, and improving the production capacity and the production benefit of the chemical production.

In addition, with the above-described production raw material addition scheme, after the production raw material addition is completed, the production raw material inventory amount in the production raw material inventory information at the production raw material management apparatus is modified according to the production raw material addition scheme, thereby ensuring the accuracy of the production raw material inventory information maintained at the production raw material management apparatus. In addition, in the case that the production raw material inventory information maintained at the production raw material management device has configurable raw material attribute information, the configurable raw material attribute information in the production raw material inventory information at the production raw material management device can be modified according to the production raw material addition scheme, so that the production raw material inventory information maintained at the production raw material management device is more in line with the actual use condition of the production raw material.

In response to a match in usage attributes of the production stock required by the first chemical production order and the remaining production stock of the last chemical production order, and the remaining production stock having downward compatibility with respect to the production stock required by the first chemical production order, the stock-utilization determining module determines that the remaining production stock of the last chemical production order has stock-utilization.
