Skid-mounted natural gas liquefaction system adopts modular integration technology, integrating pre-treatment and pressure regulation, deep purification, hybrid refrigeration and liquefaction as well as intelligent storage and transportation, and the core unit is highly integrated through standardised skid blocks (12m×3m×3.5m). For the scenario of daily processing capacity of less than 30,000 cubic metres, the first compressor and cold box integrated design eliminates the on-site refrigerant pipeline connection, reducing the risk of leakage by 90%, and the overall system occupies 40% less space than traditional equipment. Through the flexible combination of 3-6 standard skids, the system can be expanded to 300,000 m3/day processing capacity, which is suitable for the development of marginal gas fields, shale gas wells and other decentralised gas sources.
