The following detailed operating procedures of the process of the present invention are given as examples to further illustrate the invention. It is to be understood that the following examples are illustrative only, and are not limiting upon the scope of the invention.
Examples
As shown in fig. 1, a method for monitoring a crude oil migration process of the present embodiment includes the following steps:
(1) decomposing the storage and transportation process flow of crude oil provided by a certain refinery enterprise in different areas;
(2) drawing the sub-units belonging to the same sub-process and separated in the step (1) into sub-process diagrams corresponding to the sub-processes according to the moving direction of crude oil in the crude oil storage and transportation process flow; and
(3) and combining the sub-units in the drawn sub-flow chart to make an oil storage table for recording the oil storage types in the oil pipelines of the sections in the corresponding sub-flow and the time of stopping the transportation of the crude oil.
Wherein, the specific decomposition mode of the step (1) is shown in fig. 2, and comprises the following steps:
(a) crude oil routes in crude oil storage and transportation process flows of a plurality of different areas are decomposed into different sub-modules according to different crude oil storage and transportation functions. In the refining enterprise, the submodules are respectively submodule 1 (a set of crude oil routes with an oil unloading function), submodule 2 (a set of crude oil routes with a pumping function) and submodule 3 (a set of crude oil routes with a tank switching function);
(b) the sub-modules are decomposed into a plurality of sub-processes corresponding to the respective crude oil routes. Each route decomposed by submodule 1 refers to the route of crude oil entering the crude oil storage tank from the berth (unloading line). In the refinery, sub-module 1 is decomposed into 4 sub-processes, which are respectively denoted as 010# oil unloading line (i.e., CO-010 oil unloading line, as shown in fig. 5), 011# oil unloading line, 020# oil unloading line, and 021# oil unloading line. Each route obtained by the decomposition of the submodule 2 refers to a route (pump inlet line) in which crude oil passes from a storage tank through a pump and finally enters a crude oil blending area. Sub-module 2 is divided into 5 sub-processes, which are respectively marked as 101# pump-in line (as shown in fig. 3), 102# pump-in line, 103# pump-in line, 104# pump-in line, and 701# pump-in line. Decomposed by the submodule 3 of the refining enterprise to obtain the transit line with the tank-pouring function. Sub-module 3 is broken down into 1 sub-flow, denoted as 712# transition line (i.e., CO-712 transition line, as shown in FIG. 4); and
(c) the sub-process is broken down into a plurality of sub-units corresponding to the respective crude oil movement equipment. For example, the 010# unloading line in sub-module 1 is broken down into sub-unit 1 (crude tank), sub-unit 2 (valve), sub-unit 3 (oil pipeline), and sub-unit 4 (berth); the 101# pump inlet line in sub-module 2 is broken down into sub-unit 1 (crude tank), sub-unit 2 (valve), sub-unit 3 (oil pipeline), and sub-unit 5 (pump); the 712# transfer line of sub-module 3 is broken down into sub-unit 1 (crude tank), sub-unit 2 (valve), sub-unit 3 (oil pipeline), and sub-unit 5 (pump).
The step (2) has the following characteristics:
(a) each sub-process is formed by arranging the sub-units in the sub-processes according to the moving direction of the crude oil. As shown in fig. 3, the 101# pump-in line is composed of subunit 1 (crude oil storage tank), subunit 2 (valve), subunit 3 (oil pipeline), subunit 5 (pump) and the flow direction of crude oil; as shown in fig. 4, the CO-712 transfer line (i.e., 712# transfer line) is composed of subunit 1 (crude oil storage tank), subunit 2 (valve), subunit 3 (oil pipeline), subunit 5 (pump), and the flow direction of crude oil; as shown in fig. 5, the CO-010 oil-discharge line (i.e. 010# oil-discharge line) is composed of subunit 1 (crude oil storage tank), subunit 2 (valve), subunit 3 (oil pipeline) and subunit 4 (berth), and the flow direction of crude oil; in FIGS. 3-5, "T" represents a crude oil storage tank and "P" represents a pump;
(b) 4 oil discharge lines in the submodule 1 are connected with each other through a subunit 2 (valve); as shown in fig. 5, the 010# oil discharge line is communicated with the 020# oil discharge line, the 022# oil discharge line and the 023# oil discharge line through a valve 42104, a valve 17023 and a valve 17025 respectively;
(c) among the 4 pump inlet lines in the submodule 2, the pump inlet line 104# is switched to the pump inlet line 101# and the pump inlet line 102# and the pump inlet line 103# through the submodule 2 (valve); as shown in fig. 3, the 104# pump inlet line is switched to the 101# pump inlet line through the valve 10174;
(d) submodule 1 and submodule 2 have an association: the 020# oil discharge line in the submodule 1 is switched into the 104# pump inlet line in the submodule 2 through the subunit 2 (valve); as shown in fig. 5, the 010# oil discharge line is communicated with the 502# pump inlet line and the 504# pump inlet line through a valve 15506 and a valve 15806 respectively; and
(e) submodule 2 and submodule 3 have an association: as shown in fig. 4, the 712# transfer line in sub-module 3 is transferred through sub-unit 2 (valve) to the 701# pump line in sub-module 2.
Taking the 101# pump-in line oil-retention table shown in table 1 as an example, the oil-retention table records the oil-retention type and the time when the crude oil stops being transported in each oil transportation pipeline in the 101# pump-in line shown in fig. 3. The table has the following features:
(a) one sub-process corresponds to one oil storage table, as shown in fig. 3 and 4, the 101# pump inlet line corresponds to the 101# pump inlet line oil storage table;
(b) the oil table consists of three columns: respectively recording the names of all sections of oil pipelines in the sub-process corresponding to the oil storage table, the stored oil type in the oil pipelines and the time for stopping the transportation of the crude oil;
(c) the pipeline names in the table are: the crude oil storage tank root section, the pump inlet section and the rotor. The "crude oil tank root section" corresponds to each of the "T13 tank root section" - "T16 tank root section" in the table, and refers to an oil pipeline between each crude oil storage tank and a valve corresponding to the crude oil storage tank, for example, "T13 tank root section" refers to an oil pipeline between a 13# crude oil storage tank and a valve corresponding to the crude oil storage tank. In the "section" correspondence table, "sections" T13 to T12 "-" sections "T15 to T16" and "sections" P101 to P102 "-" sections P105 to P106 "respectively refer to an oil pipeline between a root valve of a previous crude oil tank and a root valve of a subsequent crude oil tank and an oil pipeline between a valve corresponding to a previous pump and a valve corresponding to a subsequent pump, for example," sections "T13 to T12" refer to an oil pipeline between a root valve of a 13# crude oil tank and a root valve of a 12# crude oil tank, and "sections" P101 to P102 "refer to an oil pipeline between a valve corresponding to a 101# pump and a valve corresponding to a 102# pump. The "pump" corresponds to "P101" - "P106" in the table, and refers to the oil pipeline between each pump and its corresponding valve, for example, "P101" refers to the oil pipeline between 101# pump and its corresponding valve. The "pump inlet section" refers to an oil conveying pipeline between a valve at the outlet of a crude oil tank area (in this embodiment, a root valve of a 16# crude oil storage tank, namely a tank root valve of the 16# crude oil storage tank) and a valve at the inlet of a pump room (in this embodiment, a valve corresponding to a 101# machine pump). "turn" means the oil line from the valve at the outlet of the crude tank section of one pump line to the valve at the inlet of the pump house of another pump line, for example, "426 turn 273 line" means the oil line from the valve at the outlet of the crude tank section of the 104# pump line (i.e., 426 line) to the valve at the inlet of the pump house of the 101# pump line (i.e., 273 line).
The method for monitoring the crude oil moving process of the embodiment further comprises the following steps:
(4) according to the transportation condition of the crude oil in a certain sub-process, the oil storage type in the oil pipeline and the time when the crude oil stops transportation are recorded in the oil storage table corresponding to the sub-process.
For example, the site requires crude oil "carbindary oil" to enter the crude oil blending zone from a 12# crude oil storage tank through a 103# pump, and the crude oil outage time is: 8/5/10: 34 in 2018. Then for this crude oil movement process, the stored oil type and crude oil outage time recording process of the oil pipeline is as follows:
(a) firstly, finding out an oil storage table corresponding to the 101# pump inlet line: 101# pump inlet line oil storage table, and then inputting 'carbine oil' into oil storage type cells corresponding to 'T12 root section', 'T12 to T14 section', 'T14 to T11 section', 'T11 to T17 section', 'T17 to T15 section', 'T15 to T16 section', 'pump inlet section', 'P101 to P102', 'P102 to P103' and 'P103';
(b) when the crude oil stops conveying, the conveying stop time is input in the conveying stop time cells corresponding to the sections of ' T12 root "," T12 to T14 "," T14 to T11 "," T11 to T17 "," T17 to T15 "," T15 to T16 "," pump inlet section "," P101 to P102 "," P102 to P103 "and ' P103 ': 8/5/10: 34 in 2018.
The results are shown in table 1.
Table 1: 101# pump inlet line oil storage table
Note: in table 1, line 426 is 104# pump inlet line, and line 273 is 101# pump inlet line.
The method for monitoring the crude oil moving process facilitates the operator to quickly monitor the moving process of the crude oil in the 101# pump inlet line, and also facilitates the operator to record the oil storage type and the conveying condition information of each section of oil conveying pipeline contained in the 101# pump inlet line. Meanwhile, an operator can also find and correct operation errors in time by using the method or prepare for the next operation in advance, for example, before the next operation is performed, by observing the stored oil types and the recording results (table 1) of the conveying conditions of the oil conveying pipelines in each section of the 101# pump inlet line, considering that the pipelines in which the "carbine" oil is stored still have residual "carbine" oil in the oil conveying pipelines which are stopped to be conveyed, in order to ensure the stable target oil type property of the crude oil blending area, when the pipelines are reused for oil conveying, the operator can select the oil type which is similar to the "carbine" oil property, so that the operator plans a latest oil product moving instruction according to the information in table 1: in the 101# pump-in line, the "jiono" oil (the "jiono" oil and the "carbinda" oil are both low sulfur crude oils) is pumped from the T12 tank leg and the T13 tank leg through the P105 pump into the crude oil blending zone. If there is no oil type with the same or similar attribute, it is necessary to arrange the top line operation, that is, after the crude oil (residual oil) left in the pipeline during the last oil product moving is pushed into the storage tank corresponding to the residual oil by the new oil type, the new oil product moving operation is performed.
The embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made according to the purpose of the invention, and all changes, modifications, substitutions, combinations and simplifications made according to the spirit and principle of the technical solution of the present invention should be replaced by equivalents, as long as the technical principle and the inventive concept of the method for monitoring crude oil moving process of the present invention are met, and all fall within the protection scope of the present invention.
