Description

technical field [0001] The invention belongs to the technical field of storage of liquid light hydrocarbons, and in particular relates to a storage tank for storage of liquid light hydrocarbons at low temperature and normal pressure. Background technique [0002] "Hydrocarbon" is a mixture of carbon and hydrogen in different proportions, and the lighter part is called light hydrocarbon. The main component of natural gas is C1 methane, containing a small amount of C2 ethane. The main components of liquefied petroleum gas are C3 propane and C4 butane, which are gaseous at normal temperature and pressure, called gaseous light hydrocarbons. C5-C16 hydrocarbons are liquid at normal temperature and pressure, we call them liquid light hydrocarbons, which will always coexist with oil and natural gas. Liquid light hydrocarbons are the main raw materials for gas production. In the prior art, the storage methods for liquid light hydrocarbons include normal temperature and high pressu...
