Description

IMPROVED METHOD FOR DISCHARGING AGROCHEMICAL PRODUCTS FROM TRANSPORT CONTAINERS AND RELATED PRODUCTS

TECHNICAL FIELD The invention relates to the technical field of loading, transport, unloading and storage of agrochemical products. The invention is of particular importance for use in an agrochemical formulation plant as it provides a safer, more reliable and economical method for discharging agrochemicals from transport containers.

BACKGROUND

Bulk transport of agrochemical liquids is often carried out in dedicated bulk transport containers such as tanks. Dedicated transport is advantageous to avoid contamination of the product. However, it weighs heavily on transportation costs because the tanks must be cleaned after use before they can be reused for another transport. End user or intermediate storage facilities are often not equipped with tank cleaning facilities. It is therefore necessary for an empty truck to be taken to a cleaning facility before it can take a subsequent load. These costs weigh heavily, especially on the price of basic agrochemicals.

The liquid product delivered to a formulation plant for agrochemicals requires storage prior to use. It is important that the unloading and storage of these often dangerous chemicals take place safely and cost-effectively.

It is common practice to store liquid agrochemical formulations in a variety of storage tanks. Access to such tanks is generally obtained through shut-off valves mounted on the tanks. A pipeline or pipes connected to the valve connections provide the means to allow the transportation of the fluids to their destinations. The faucets on the tank systems are commonly located in a convenient position, to allow ease of use and accessibility for the user. However, the placement of faucets also makes them easily accessible to unauthorized users of tanks and misuse by people who may accidentally open an incorrect faucet, thus inadvertently releasing the contents of a supply delivery into a wrong tank storage. The object of the invention is to propose a solution to at least one of the problems mentioned above. In particular, the invention aims to provide an improved method for discharging agrochemicals from transport containers.

SUMMARY OF THE INVENTION

In a first aspect, the invention provides an improved method for discharging a liquid agrochemical formulation or agrochemical formulation aid, comprising the steps of: a) receiving a liquid agrochemical formulation or an agrochemical formulation auxiliary loaded into a transport container configured for storing, transporting and discharging a liquid, b) at least partially discharging the product from the product-laden transport container, where the discharging comprises: - selectively connecting a storage tank to the product-laden container using a duct adapted to communicate with said storage tank and said product-laden container for discharging the material contained therein, and - at least partially discharging said liquid from said container into said selected storage tank, characterized in that said selective connection of the storage tank and the product to be discharged is directed by a human-machine interface (HMI) system, wherein the direction comprises: - in said IMH system, selecting a storage tank and a conduit connectable to said storage tank suitable for receiving said liquid product, and - after approval, release a key to open a corresponding lock, said lock prevents access to a valve provided at the end of the conduit opposite the storage tank, and open the corresponding lock using the key, obtaining thus access to the faucet, and open the faucet; - after an inappropriate choice, refuse access to a key.

This method is advantageous because it allows increased safety for handling agrochemicals.

Examples of auxiliary materials are surfactants, antifoam agents, antifreeze agents, wetting agents, coloring agents, emulsifiers, thickeners, solvents.

The process is advantageously used for the storage, transportation and handling of propamocarb formulations.

The term human-machine interface system (HMI) as used herein refers to a user interface in a process manufacturing and control system. It provides graphical visualization of an industrial control and monitoring system. Previously referred to as "HMI" (human-machine interface), a HMI typically resides in a desktop-based Windows computer that communicates with a factory-specific computer such as a programmable automation controller (CAP), a logic controller Programmable Controller (CLP) or Distributed Control System (SCD). The HMI system presents the information graphically to the user staff, in the form of a block diagram. This means that the operator can see a schematic representation of the plant being controlled. For example, an image of a pump connected to a pipeline may show the operator that the pump is running and how much fluid it is pumping through the pipeline at this time. The operator can then stop the pump. The HMI software will show the flow rate of the fluid in the pipeline that decreases in real time. Synoptic diagrams may consist of line graphs and schematic symbols to represent process elements, or may consist of digital photographs of process equipment covered with animated symbols.

The term "propamocarb" as used herein refers to a compound belonging to the chemical family of carbamates. The IUPAC name for propamocarb is propyl [3- (dimethylamino) propyl] carbamate. CAS RN 24579-73-5 has been assigned to propamocarb. Its chemical structure is represented in formula (I).

¢ 1)

Advantageously, propamocarb is used in the form of its hydrochloric salt. This one has the CAS number 25606-41-1.

Unless specifically mentioned, the term "propamocarb" as used herein refers to propamocarb as such and its salts.

In a second aspect, the invention provides a liquid agrochemical formulation obtained by a method according to one embodiment of the invention, comprising 722 g / l of propamocarb.HCl or 600 g / l of propamocarb.

Highly concentrated propamocarb formulations can be advantageously handled by a process according to the invention. This results in a final product that is less expensive because savings can be made in the storage, handling and transport of the active ingredient.

In a third aspect, the invention provides a flexible bag that can be disposed within a container for transporting and storing a liquid, and configured for storing and transporting a liquid agrochemical formulation; comprising 722 g / l of propamocarb.HCl or 600 g / l of propamocarb.

In the prior art, the transport of these highly concentrated solutions of propamocarb is by tanker. After the product is removed from the container, it is returned empty. A cleaning operation is necessary before it can be reused. This makes transportation time-consuming and therefore expensive. Propamocarb.HCl is not compatible with a metal tank. A flexible tank package, made of plastic, offers an interesting alternative. The advantage of using a flexible wall container is that after unloading the container, it can be folded and removed from the shipping container. This leaves a shipping container uncontaminated and therefore it is not necessary to clean the shipping container before the container can be used again. This is compared to conventional bulk transport of chemicals and pesticide active ingredients, where the bulk is transported in a tank. After unloading, the tank must be cleaned before other substances can be transported into the tank. The empty but contaminated tank must move to an installation to clean the tank. This results in additional mileage added to the transport to be taken to the cleaning facilities, extra time required for the truck driver, additional cost of cleaning the tank and the fact that the tank is out of service until the tank be cleaned.

The flexible bag container is preferably removed from the shipping container after unloading and can be recycled, landfilled or burned. The inventor has found that a highly concentrated solution of propamocarb can be safely packaged and transported in a bladder-type package configured for storing and transporting a liquid agrochemical formulation.

In a fourth aspect, the invention provides a kit of parts for storing, transporting and discharging a liquid agrochemical formulation or agrochemical formulation aid, the kit comprising: a) a container configured for storage, transport and discharge of a liquid agrochemical formulation or agrochemical formulation auxiliary comprising at least one product inlet, and at least one product outlet, positionable within the transport means; b) first and second conduits connectable to said product inlet and product outlet, the first conduit for conveying fluid into said container, the second conduit for conveying at least a portion of the product from said container during discharge; c) means for selectively authorizing or prohibiting access to a storage tank for discharging said formulation from said container at an end user or intermediate storage facility, characterized in that said means comprises: a human-machine interface system (HMI) configured to select a storage, a third conduit connected to said storage tank suitable for receiving said liquid product and provided at its opposite end to said storage tank a valve configured to have a lock, and a key and a corresponding latch for providing selective access to said valve.

The kit of parts can be advantageously used in a method according to the invention.

In a last aspect, there is provided a use of a flexible bag disposed within a transport means for storing and transporting a liquid agrochemical formulation or agrochemical formulation aid.

This method is advantageous because it allows increased safety for handling agrochemicals.

By the term "a container configured for the storage, transport and discharge of a liquid agrochemical formulation or agrochemical formulation aid" as used herein is meant a shipping container suitable for storing, moving and unload chemicals. Examples of suitable containers for use in the invention are tanks and flexible tanks. As a result, the container is inert to the filler, i.e., a liquid agrochemical formulation or agrochemical formulation aid.

In a preferred embodiment of a method according to the invention, said conduit is connected to said product-laden container using a flexible hose provided on each side with quick-connect fittings. The use of this type of connector also contributes to reducing the time required to unload the transport container.

In a preferred embodiment of a method according to the invention, the container is a flexible bag and said means of transport is a shipping container. The flexible bag is positioned inside the shipping container.

A method according to one embodiment of the invention using a flexible bag has the advantage that an efficient and safe transport system is provided, requiring minimal movement of empty contaminated containers or empty contaminated shipping containers. This makes the production of the pesticide composition and the pesticide composition itself more environmentally friendly. The total amount of CO2 emissions will be reduced, and fewer resources will be needed during production. Any rigid "transport container" mentioned herein is intended to include both a shipping container and a road trailer container. That is, the shipping container and the road trailer container are each qualified as a "container" as defined above. For example, each of them has a structure with the dimensions mentioned above. The term shipping container (also called a "container") is well known by people involved in the shipping industry. The shipping container is capable of being used to ship (transport) large amounts of cargo over long distances, typically on water, on ships or barges, or on land on wagons. A road trailer container, on the other hand, is a container that also includes a chassis and wheels, and a structure for securing the chassis to any truck having a diesel engine.

As used herein, the term "shipping container" is defined as any rigid box-type structure having two vertically opposed sidewalls that are at least 10 feet in length and preferably up to 10 feet in length. at 60 feet; a height of at least 6 feet and preferably up to 12 feet; and a width (generally corresponding to the space between the two opposite side walls) of at least 6 feet and preferably up to 12 feet. The container also has a floor that is substantially the same length as the two side walls, and an end wall that is disposed between the side walls at the end of the container, which will be referred to herein as the "back wall" (also called the "closed end wall" or the "closed end" or the "end wall") of the container. The container also has an end opposite the closed end, which end will be referred to herein as the "leading end" or "open end" of the container. The container has one or more doors, which are flat elements positioned at or near the open end which are capable of opening or closing.

At least one embodiment of the container also includes an upper member, or "lid", which is used to secure the bladder within the container during transportation (shipping). Preferably, the lid is formed of a grid with bars which are formed in a cross arrangement. Each of the side walls, and the rear wall, have an inner (inner) and an outer (outer) surface. As illustrated in some drawings herein, each container has an overall interior surface, which is irregular or wavy (sometimes referred to as "lazy" ripples) but is nevertheless considered to be "substantially planar" as this term is used herein.

As discussed in more detail below, the overall surface of each of the walls of the rigid container has sub-surfaces (inside and outside the container), which are described in more detail here and are also designated as "surfaces". Also, for clarification, when reference is made here to any container which has flexible walls, this container will be designated either as a bladder or as a "bladder", or in some cases this container will be designated as an envelope ".

As used herein, a "bladder" is defined as any flexible structure that includes a flexible container having a length and a width, one or more internal surfaces, one or more external surfaces, an interior (at interior) capable of containing fluidifiable liquids or solids, and one or more openings through which a fluid is capable of passing into or from the interior of the bladder.

There are many different sizes and types (embodiments) of flexible tanks, for example, different categories and / or subcategories of flexible tanks. For example, different types of flexible tanks may have or include different sizes, shapes, materials, and components (for example, fixtures and / or hardware, including fittings). Thus, unless stated otherwise, or unless it is apparent from the context, all of the references here to a "bladder" encompass any and all of the many different types of bladders. The flexible container component of the bladder may be, for example, a single layer bag or a multilayer bag. The flexible container may also be a combination of bags or diapers or liners in which one, one or more bags or layers or liners are disposed within one, one or more other bags or layers or liners (discussed below). Alternatively, the flexible container may be a laminated bag, comprising different layers laminated together. As discussed herein, the inner surface of the flexible reservoir defines the interior of the flexible container (e.g., an internal cavity). Unless otherwise indicated, in one embodiment of the bladder in which one or more bags are disposed within one or more other bags, the "outer surface" of the bladder refers to the outermost surface of the bladder or the outermost bag, while the "inner surface" of the bladder is the innermost surface of the innermost layer or bag, which surface is designed for, or capable of being in contact with, the load, for example, the liquid or fluidifiable solids that are included or contained in the bladder. Thus, for example, a multi-layered bladder may have one or more intermediate layers that are sandwiched between 2 other layers, which intermediate layer (s) provide neither an outer bladder surface nor a bladder inner surface. The outer surface of the bladder defines the outside of the bladder. The bladder is necessarily capable of containing any of a variety of flowable materials, such as any liquid (such as wine), or a slurry.

A particular bladder may be in a filled condition (filled, partially filled, or fully filled), for example, if the liquid occupies the interior of the bladder. Alternatively, the bladder may be in an empty condition (condition).

As discussed below, the bladder includes not only the flexible portion (eg bags), but also at least one opening. The bladder that includes separate independent layers also preferably includes at least one fitting corresponding to at least one opening, which fitting may include one or more flanges or any mechanical connection that clamps the layers together around the opening. The bladder is preferably "elongated" which, as used herein, means that the bladder has a length and a width, with the sides defining the length (e.g., opposite sides) being longer than the ends (for example, the opposite ends) that define the width.

When the bladder is empty and lying flat on the ground or on another horizontal surface (for example, the floor of a rigid shipping container), the bladder is preferably rectangular. In the rectangular embodiment, the two sides in the direction of the length of the rectangle are parallel to each other; and both ends of the rectangle are parallel to each other. When the bladder is filled (substantially or completely), it has a length and a width, and it also has a height. When the bladder is filled, it preferably has an oblong shape. For example, a bladder that is substantially or completely filled may be pillow-shaped, as shown in some drawings herein.

The bladder has an overall size, including all of its dimensions, such that it is able to fit in a rigid shipping container, both in an empty state and in a filled state. For example, a bladder may have a length of 5, or 15, or 20 feet, up to 30, or 50, or 60 feet. This bladder may have a width of 3, or 4, or 5 feet up to 6, or 8, or 12 feet. The bladder can have a height (when filled) ranging from 1, or 2, or 3 feet up to 4, or 7, or 10 feet. The flexible tanks have dimensions (length, width and height) such that, both in an empty and filled condition, they can fit inside any rigid container with which they are used.

They can have a volumetric capacity ranging from anywhere from 5000 liters to 30,000 liters. The bladder may have a plurality of different components, including bags or sheets from which the bladder is made. For example, as noted above, some flexible reservoirs include a combination of bags (sometimes also referred to as "bladders"), where the bags are disposed within other bags.

The bladder may also have one or more openings (orifices) in the flexible material itself whereby a liquid may be introduced into, or discharged from, the interior of the bladder. Examples of such openings include an inlet opening, a discharge opening and / or an aeration opening. Other components are structures associated with each of the openings such as, for example: a discharge valve with a handle that is capable of being rotated from a closed position to an open position; a fitting for the discharge valve which may include one or more flanges; an air duct associated with a vent opening for venting air from within the bladder; and a connection for the vent pipe which may include one or more flanges. The use of a bladder type container, such as a rhino bag or a jumbo bag, instead of a cistern, is advantageous for reducing transportation costs.

In a preferred embodiment, a shipping container provided with a flexible bag further comprises a two-piece steel partition; preferably said partition is equipped with a valve connected to the contents of said flexible bag. The partition provides a good fit to a hose that can be used for loading and unloading. A safe hose connection is necessary to prevent losses.

At least one specific embodiment of a shipping container system includes a rigid shipping container, a bladder disposed within the rigid shipping container; and a partition assembly that includes one or more of the novel features discussed below or elsewhere herein. For example, at least one specific embodiment of a shipping container system comprises a rigid shipping container having at least one floor, a first side wall with an inner surface of a first side wall, a second side wall with a an inner surface of a second side wall, a rear wall having a rear wall inner surface and an open end; a flexible reservoir disposed within the rigid shipping container, in the space between the two side walls; and a partition assembly comprising two shims and at least one partition panel which is disposed horizontally between the side walls of the container. The bulkhead assembly is interposed between the bladder and the open end of the rigid shipping container, or the gates (when the gates are in the closed position).

As discussed elsewhere herein, certain specific embodiments of the shipping container system include only a single bulkhead assembly, which may be (for example) a front end bulkhead assembly or an intermediate bulkhead assembly. Other specific embodiments of the shipping container system include both a front end bulkhead assembly and an intermediate bulkhead assembly.

A front end wall assembly may be any bulkhead assembly positioned near the container doors which includes a structural member (eg, a bolt or a support housing or a support wedge) disposed thereon. inside the lashing channel. In some embodiments, the front end wall assembly includes at least one horizontal bulkhead panel and at least two spacers, as defined herein further, which may be spacers that include vertical channels for receiving a bulkhead. outer edge of the partition panel. Other specific embodiments of the front end wall assembly are discussed below, and elsewhere herein, including in the drawings. The single wall assembly may also be an intermediate partition assembly that is positioned within the rigid container at an intermediate point (location) in the rigid container. As noted above, any partition assembly mentioned herein includes at least one partition panel disposed horizontally between the two side walls of the rigid container. The intermediate partition assembly is disposed between two "intermediate" points (locations) on the opposite side walls of the rigid container. The term "intermediate" in this context means any location along the side walls of the rigid container which is 30% to 70% of the total distance from the back wall of the rigid container to the front end. In some embodiments, an intermediate point is a point midway between the container's rear wall and the front end, which would be 50% of the total distance.

More preferably, the flexible bag is prevented or prevented from collapsing during the discharge.

In a preferred embodiment of a method according to the invention, said flexible bag is disposed after unloading.

The removal of the flexible bag from the transport means has the advantage that the transport means is again free, does not require cleaning, and is available for transporting another load.

In a preferred embodiment of a method according to the invention, said flexible bag is made from an opaque material.

This has the effect that the fill level can be visible. This has the advantage that a visual inspection can be performed during the loading and unloading of the flexible plastic bag. The visual inspection can avoid overfilling the flexible bag of the plastic shipping container or can detect when unfolding during filling is going wrong.

In a preferred embodiment, said flexible bag is dimensionally stable up to 60 ° C.

By the term "dimensionally stable" as used herein is meant that the form or strength is not lost up to a temperature of 60 ° C.

This has the advantage that viscous liquids can be heated up to 60 ° C to lower the viscosity of the liquid to accelerate loading and unloading.

In a preferred embodiment of a method according to the invention, the flexible bag is substantially seamless. This has the effect of reducing the risk of leaks. Discharge equipment required to discharge liquid from a bulk liquid reservoir or a flexible bag is typically located on the transport vehicle, for example a truck. The discharge equipment is located on the transport vehicle so as to be easily and permanently coupled to the PTO of the transport vehicle. Discharge equipment commonly used for pumping liquid from a tank into a storage vessel includes a power take-off operatively coupled to the transmission of the transport vehicle, a drive shaft operably coupled to the power take-off and a liquid pump operatively coupled to the drive shaft. The liquid pump is connected by liquid conduits which extend between the transport vehicle and the liquid pump, and between the liquid pump and the storage container. Discharge equipment commonly used to pressurize a bulk liquid tank and to discharge liquid directly into a storage vessel includes a power take-off operatively coupled to the transmission of the transport vehicle, a drive shaft coupled with operatively to PTO transmission and a dry piston or oil lubricated compressor operatively coupled to the drive shaft. As previously described, the compressor is connected by a pneumatic line extending between the compressor and the tank trailer, and a liquid line extending between the tank trailer and the storage vessel.

In a preferred embodiment of a method according to the invention, the discharge of the product is assisted by compressed air supplied by a pump controlled by the Human Machine Interface (HMI). The use of a pump that is under the control of the HMI system is beneficial to achieve increased safety of operations.

In a preferred embodiment of a process according to the invention, the agrochemical formulation is in the form of a soluble concentrate (SL). The use of this type of content is advantageous because the amount of water is kept to a minimum.

More preferably, the soluble concentrate is 722 g / l propamocarb or 600 g / l propamocarb. Most preferably, the concentration of the agrochemical formulation in the product laden vessel is measured and, if desired, is diluted with water to obtain 722 g / l propamocarb.HCl or 600 g / l propamocarb.

In the prior art, the transport of these highly concentrated solutions of propamocarb is by tanker. After the product is removed from the container, it is returned empty. A cleaning operation is necessary before it can be reused. This makes transportation time-consuming and therefore expensive. The inventor has found that a highly concentrated solution of propamocarb can be safely packaged and transported in a bladder-type package configured for storing and transporting a liquid agrochemical formulation.

In a preferred embodiment according to the invention, said flexible bag is made from a plastic material, preferably a polyethylene (PE), preferably a low density polyethylene (LDPE), still more preferably a linear low density polyethylene (LLDPE). ).
