Experience exchange on LNG production technology
Thread Content
In LNG production, the process utilizes a mixed refrigerant cooling system, with the refrigerants being methane, ethylene, propane, isopentane, and nitrogen. Question: What is the impact and effect of adding each type of refrigerant on the cryogenic box?
There are also discussions about LNG; this industry isn’t that great
Indeed, the LNG industry is not growing at such a rapid pace anymore, but there is still considerable room for development. It depends on policies as well as domestic and international markets; it’s not to the point where it can’t be discussed at all... The five types of refrigerants have different cooling capabilities and different points of phase change. In order from lowest to highest temperature, the gases that produce low temperatures are: nitrogen, methane, ethylene, propane, and isopentane. The locations are in order as follows: supercooled nitrogen methane, liquefied ethylene, pre-cooled propane isopentane (the location division depends on the design concept of the cryogenic tank……)
