Description

  The present invention relates to a method for transporting liquid chloride.

Liquid chloride refers to a liquid compound containing chlorine. One type of liquid chloride is debrominated bitter juice, which is obtained by removing bromine from the bitter juice and is classified as magnesium chloride. However, the present invention is also applied to liquid chlorides other than debrominated bitter juice.
The liquid chloride as described above has a property of easily corroding steel materials such as stainless steel and generating cracks, so use of tankers, tank trucks, and tank equipment for cargo handling is avoided. There are special ships that line the inside of the tank with FRP, but it is difficult to arrange due to the small number.

From the above situation, the transportation of liquid chloride has the following problems.
1) Since the number of chemical tankers that can transport liquid chloride is small, it is difficult to arrange, and stable supply of products to customers (chemical product manufacturers) is difficult.
2) Charter costs for chemical tankers are high. Also, the tanker load capacity does not match the one lot received by the customer.
3) Since tanker trucks dislike transporting chlorides, land transportation arrangements are difficult.
4) Unloading is only possible from the port dedicated to handling liquid cargo. Also, it is difficult to arrange tanks for shipping at dedicated ports because they dislike being able to put chloride.
5) Liquid cargo cannot be exported from general trade ports without packing that can be suspended.
6) It is necessary to transport liquid cargo to a port without cargo handling facilities.
7) The price of the liquid transport container itself is high when using a high existing liquid transport container and transporting by bulk carrier for solid cargo.
8) The transportation efficiency when returning the container for liquid transportation is extremely poor.

By the way, as a method for transporting liquid cargo by sea, there is a conventional technique of Patent Document 1.
This prior art is a method in which liquid cargo is accommodated in a filling bag, and the filling bag is loaded on a cargo ship and transported. The purpose is to prevent the spillage of crude oil and the like when the hull is damaged.

  Therefore, the prior art cannot solve the above-mentioned problems peculiar to liquid chloride.

JP 2002-308179 A

  In view of the above circumstances, an object of the present invention is to provide a transportation method capable of increasing the transportation efficiency of liquid chloride.

  The method of transporting liquid chloride according to the first aspect of the present invention comprises a transport bag capable of filling and taking out liquid chloride and a lifting member for handling the transport bag, and the transport bag is resistant to liquid chloride. It has toughness and foldable flexibility, and it is characterized by placing a transport bag in a lifting member during cargo handling and loading only the transport bag on a transport ship or land transportation means during transport. .

According to the first invention, the following effects are obtained.
First, since the liquid chloride is filled in a transport bag and transported, it does not directly contact a steel tank, pump, piping, etc., and corrosion or cracking of these facilities can be prevented. For this reason, the following advantages arise.
1) Since chemical tankers are not used and general cargo ships can be used, transportation costs are reduced and stable supply to customers is possible.
2) It is possible to load and unload at general trade ports without using a dedicated port for handling liquid cargo.
3) There is no need to use containers or tanks for transporting liquids, thus reducing transportation costs. Moreover, since the container takes a large space when returned, the transportation efficiency is poor.
4) Since it is not necessary to use a tank truck, land transportation becomes easy.
Secondly, since the transport bag and the lifting member are separated, it is sufficient for the lifting members to be used in the cargo handling area, and it does not move together with the transport bag, which is economical. Moreover, since it is a separate body, it is possible to employ a member that is sufficiently strong in strength, and it is easy to prevent accidents during cargo handling.

Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a state in which a transport bag used in the transport method of the present invention is placed in a lifting member. 2A is a perspective view of a transport bag, and FIG. 2B is a perspective view of a lifting member. FIG. 3 is an explanatory view of the transportation method (first half) of the present invention. FIG. 4 is an explanatory view of the transportation method (second half) of the present invention.

FIG. 2A shows a liquid chloride transport bag 1. The shape is generally a square cube, but the corners and edges may be rounded. It is better to be close to a cube in terms of volumetric efficiency of loading, and closer to a sphere in terms of ensuring strength, but any shape may be adopted between the cube and the sphere.
The size is not particularly limited, but the larger the size, the higher the cargo handling efficiency. However, if it is too large, it is difficult to move it manually. Therefore, one side is easy to handle around 1 m, but it may be smaller or larger. In addition, if the external dimensions are easy to fit in the truck or tanker cargo room, the transportation efficiency will be higher.

  The transport bag 1 is provided with a valve 2 for filling with liquid chloride and a valve 3 for taking out. These valves 2 and 3 may be any valves as long as they are watertight and easy to open and close.

It is essential that the material of the transport bag 1 has resistance to liquid chloride.
In addition, considering the convenience of transportation, it is also important to satisfy the following conditions.
1) Flexible enough to be folded 2) Excellent pressure resistance 3) Excellent wear resistance 4) Light weight (portable weight)
5) Excellent airtightness Any material that satisfies these conditions may be used.

  FIG. 2B shows the lifting member 6. The lifting member 6 only needs to have a function of holding the transport bag 1 and lifting it. For this reason, it is made to a size somewhat larger than the transport bag 1. The cords shown in the figure may be assembled in a lattice shape or a bag shape. In short, it suffices if there is a hook portion 8 to be hooked with the support member 7 that supports the transport bag 1.

FIG. 1 shows a state in which a transport bag 1 filled with liquid chloride is accommodated in a lifting member 6. In this state, when the hook portion 8 is hooked on the crane hook F or the like, cargo handling by mechanical force can be performed.
Note that when a wire or the like is passed through the hook portions 8 of the plurality of lifting members 6 and the wire or the like is hooked on the crane hook F, the plurality of transport bags 1 can be lifted at a time.

  Secondly, since the transport bag and the lifting member are separated, it is sufficient for the lifting members to be used in the cargo handling area, and it does not move together with the transport bag, which is economical. Moreover, since it is a separate body, it is possible to use a member that is sufficiently strong in strength, and it is easy to prevent accidents during cargo handling.

Next, an example of the transportation method of the present invention will be described based on FIG. 3 and FIG.
A) Cargo shipment of export side manufacturer The transport bag 1 is filled with liquid chloride, and this is loaded into land transportation means such as trucks and railroads by any cargo handling means such as forklifts and cranes.
B) Land transport Transport by truck or freight car. Since there is no need to use a tank truck, the arrangement is easy and the cost is low.

C) Cargo handling at the export port At the port, the transport bag 1 is loaded from the truck etc. into the transport ship. If the lifting member 6 is used at this time, the mechanical force of a crane or the like can be used, so that the efficiency is good.
The transport ship may be a general bulk carrier, which is easy to arrange and inexpensive. The port does not need to be a dedicated port for liquid cargo and can be used as a general trade port.
D) Sea transport by bulk carriers There is no need to use chemical tankers and general bulk carriers are used, so the cost is low. Further, the loading amount can be arbitrarily adjusted by adjusting the number of transport bags 1.

E) Cargo handling at the import port Cargo can be handled efficiently as in C).
F) Land transport It can be carried out at a low cost as in B).
G) Cargo handling of the importing manufacturer Same as A) H) Completed delivery The importing manufacturer takes out the liquid chloride by opening and closing the valves 2 and 3 within the company.

I) Liquid cargo container 10
After emptying the liquid chloride, the empty transport bag 1 is folded, several sheets are put together, put into a dedicated transport container 10 and prepared for return.
J) Container loading of return container This is done by any cargo handling means such as a forklift. Since the transport bag 1 is folded small and accommodated in a container, the transport efficiency is increased.
K) Land transport Any truck service can be used for land transport.
L) Container ship maritime transport General container ships can be used, so the ship price will be reduced.
M) Land transport Same as K)

N) Arrival at imported manufacturer Unload with a forklift.
O) Preparation for shipment When the transport bag 1 is filled again with liquid chloride, it can be shipped.

The advantages of the transportation method of the present invention are summarized as follows.
1) It can be transported by sea on a bulk carrier for solid cargo, which is relatively easy to arrange.
2) Ports can be handled by cranes on both the export side and the import side as with solid cargo.
3) Both the export side and the import side can carry out land transportation by solid cargo truck.
4) Since the container can be folded small, the transportation efficiency at the time of return is high.
5) The cargo handling work with a crane is possible, so the cargo handling efficiency is high.

It is a perspective view of the state which put the transport bag used for the transport method of the present invention in the lifting member. (A) is a perspective view of a transport bag, and (B) is a perspective view of a lifting member. It is explanatory drawing of the transportation method (first half) of this invention. It is explanatory drawing of the transportation method (latter half) of this invention.
