Description

Technical Field

[0001] This utility model relates to the field of LNG storage tank transportation technology, and in particular to an LNG storage tank with heat preservation and pressure reduction functions. Background Technology

[0002] Liquefied natural gas (LNG), primarily composed of methane, is widely recognized as the cleanest fossil fuel on Earth. It is colorless, odorless, non-toxic, and non-corrosive, with a volume approximately 1 / 625th that of the same amount of gaseous natural gas, and a mass only about 45% that of the same volume of water. Its production process involves purifying natural gas produced from gas fields, followed by a series of cryogenic liquefaction processes, and then transporting it using LNG carriers. LNG combustion produces very little air pollution and releases a large amount of heat, making it a relatively advanced energy source.

[0003] LNG storage tanks are crucial equipment for receiving, storing, and transporting LNG. In existing technologies, multiple LNG storage tanks are often transported at once. During transport, especially on bumpy roads, these tanks can vibrate and collide, posing a safety hazard. Therefore, this invention provides an LNG storage tank with insulation and pressure reduction functions to address the problems mentioned in the background section. Utility Model Content
