Abstract

The invention provides a marine flammable ice mining gas solidification storage and transportation system. According to the marine flammable ice mining gas solidification storage and transportation system, production water and methane gas obtained by mining flammable ice are conveyed into a flammable ice synthesis pretreatment system through a mining platform, the production water and the methanegas are pretreated through the flammable ice synthesis pretreatment system and are conveyed into a methane gas solidification device, and the methane gas solidification device is used for synthesis, compressing solidification and molding treatment of the flammable ice and conveying the treated flammable ice into a flammable ice storage device for storage and transportation. The invention further provides a marine flammable ice mining gas solidification storage and transportation method, synthesis, cooling, pressure reducing and compression molding of the flammable ice are performed through themethane gas solidification device, long-distance transportation of the flammable ice in a lower pressure environment is realized, the high cost expenditure of liquefied natural gas ultralow temperature transportation is effectively avoided, and the risk of explosion in the liquefied natural gas transportation process is reduced.

Description

technical field [0001] The present invention relates to the technical field of development, utilization, storage and transportation of marine combustible ice resources, and more specifically, to a system and method for solid-state storage and transportation of gas from marine combustible ice mining. Background technique [0002] Combustible ice, also known as natural gas hydrate, is a crystalline clathrate compound formed by gas molecules (mainly methane molecules in nature) and water molecules under high pressure and low temperature conditions. Because of its wide distribution, large reserves, The advantages of high energy density, clean and pollution-free combustion are known as the most potential alternative energy in the 21st century. [0003] Although the patent application (publication number: 108192684A) continuous preparation device and preparation method of block combustible ice discloses a preparation method of block combustible ice, in the actual application proce...
