AI Technical Summary
In existing floating structures, the presence of separators and subcooling devices during the transportation and storage of liquid gases results in large system space occupation and high costs, and makes it difficult to effectively manage the reliquefaction and pressure control of gaseous gases.
By combining a gas supply circuit, heat treatment pipeline, cooling pipeline and mixing device, and through a compression device, heat exchanger and pumping device, the gaseous gas is reliquefied and pressure regulated, eliminating the need for a separator and subcooling device. The mixing device mixes the gas at the bottom outlet of the tank to ensure complete reliquefaction of the gas.
It achieves a compact and economical gas management system, avoiding the space and cost of separators and subcooling devices, ensuring effective reliquefaction of gaseous gases, and reducing the overall size and operating cost of the system.
