LNG gasification skid directly utilizes cold energy for power generation, liquefaction and separation of air (liquid oxygen, liquid nitrogen), freezer warehouse, liquefied carbonic acid, dry ice, air conditioner, etc.; indirect utilization includes frozen food, low-temperature crushing waste treatment, freezing preservation, food preservation Wait. The use of cold energy not only depends on the size of its energy recovery, but also on the use of quality.
The temperature of liquefied natural gas is about -160°C, which is very low temperature. LNG is a clean fossil fuel, and it is a conventional fuel with the highest "calorific value" per unit mass (because it has also input a lot of work in the preparation process to compress, freeze and liquefy it. Cold energy, the generation of LNG requires a lot of work, and when it is re-gasified, the energy should be recovered. In the case of economical, reasonable, safe and stable conditions, it must comply with the principle of the total energy system of temperature matching and utilization.
