Description

technical field [0001] The invention relates to the technical field of compressed natural gas, in particular to a mobile gasification pressurization system and method. Background technique [0002] At present, the domestic Compressed Natural Gas (CNG) gas supply business is mainly carried out by enterprises that have obtained the nationally recognized dangerous goods business license for CNG transportation and supply. Users who use CNG need to use natural gas through the construction of receiving equipment. The method requires users who use CNG to have sufficient funds for asset investment before they can use CNG, which has the disadvantages of large investment, high risk, and low return on investment. Specifically, it is manifested as: (1) It occupies a large area, and it is difficult for the existing site High requirements; (2) End-user equipment has a single receiving capability and poor adaptability; (3) End-users have high capital requirements; (4) Gas supply companies ...
