Problems solved by technology

[0007] However, in the transportation method using this bag and container, manual or mechanical work is required for bagging the pellets, storing them in the container, tearing the bag for opening, and taking the pellets out of the bag. Homework, the problem of poor efficiency
In addition, there is a problem that packaging materials such as bags used for small batch transportation of pellets become wasteful resources.

Embodiment Construction

[0031] Hereinafter, the water transport method of the polymer particles according to the present invention will be described with reference to the drawings. In addition, although the bulk carrier which has a propulsion device is demonstrated here, this invention can be similarly employ|adopted also if the barge for bulk which does not have a propulsion device is used. In addition, the attached drawings are diagrams for explanation, and are not necessarily diagrams based on a ship type used in an actual ship and dimensions of a cargo warehouse. also, Figure 9 It is also a diagram used to illustrate the loading and unloading methods of goods. Figure 9 hull structure and Figure 1 to Figure 8 Compared with the hull structure, the hull structure is different in the shape of the cargo warehouse and the discharge port.

[0032] First, with regard to the bulk ship used in the water transportation method of polymer particles according to the embodiment of the present invention, the...

Abstract

Provided is a water-borne transportation method for polymer pellets whereby it is possible to efficiently transport polymer pellets powder particles for which damage, contamination, or moisture is unfavorable. Polymer pellets (B) are transported over water by being stowed in bulk in a cargo hold of a ship (1 or 1A) or a barge. Furthermore, for the purpose of preventing the surfaces of the polymer pellets (B) from being damaged by colliding with support members in the cargo hold, the polymer pellets (B) are transported by being stowed in bulk in a cargo hold (10 or 10A) wherein the walls with which the polymer pellets (B) are in contact are formed smoothly without being provided with support members protruding inside the cargo hold (10 or 10A).

Description

technical field [0001] The present invention relates to a method of water transport of polymer granules in which polymer granules transported in bulk in bulk without causing damage or contamination in bags are transported over water. Background technique [0002] In the petroleum refining industry, crude oil is distilled and separated into petroleum gas, gasoline, naphtha (crude gasoline), kerosene, light oil, heavy oil, and asphalt through the difference in boiling point. The naphtha among them is heated and decomposed by a naphtha decomposer to change it into a substance with a simple structure, and it is extracted according to substances such as ethylene, propylene, and butene. Polymers (polymers) such as polyethylene or polypropylene with different properties are produced by chemically reacting ethylene or propylene to bind molecules of the same substance. [0003] The polymer particles are made of low-density polyethylene, high-density polyethylene, transparent and cry...
