Refrigerant-mixing natural gas liquefaction device and technology thereof

Abstract

The invention discloses a refrigerant- mixing natural gas liquefaction device and a technology thereof. Each refrigerant feed pipe is connected with a refrigerant mixing tank (10) which is connected with a compressor (11). The compressor is sequentially connected with a splitter (12) and a refrigerant forward channel inlet of a heat exchanger (13). An outlet of a refrigerant return channel which is connected with the refrigerant forward channel of the heat exchanger (13) is connected with the compressor (11). A purified natural gas inlet pipe is sequentially connected with a natural gas channel of the heat exchanger (13) and a liquefied natural gas output pipe (15). The mixing refrigerant natural gas liquefaction device and the technology thereof have the advantages of simple process, high efficiency, low power consumption, low production cost, low operating cost, easy maintenance and overhaul, and light work load. Besides, allocation of the refrigerant is greatly simplified, the refrigerant component parameters is wide in the adjustable range, strong in adaptability, and rapid and convenient in adjustment, so that the entropy production in the liquefaction process is minimized, and the efficiency is improved.

AI Technical Summary

Benefits of technology

This patented technology allows for efficient use of compressed gases during cryogenic processes such as liqueficating Natural Gas or producing LNG without consuming too much electrical input from an external source like electricity. It also includes simplified configurations with multiple components and optimized settings based on various factors including ambient temperatures and pressures at which it operates effectively. Overall this results in improved efficacy over existing methods used alone.

Problems solved by technology

This patents describes various methods for efficiently producing liquid fuel from coal or other fossil fuels like oil shale. These techniques involve converting these materials into liquids before being stored underground or utilized directly without further processing steps. However, current technologies have drawbacks including safety concerns due to flammability hazards associated therewith.
