A mobile LNG refueling station integrates LNG low-temperature storage tanks, pump sleds, gas dispensers, etc. on one sled, and integrates the control room (station control part), instrument air, compressor instrument air, employee management room, etc. on another sled. The two sleds are connected by process pipelines and electrical lines. The equipment has a small footprint, does not require high site requirements, does not require planning, is easy to install, has a short construction period, needs to be improved in product specifications, comes with safety release and leakage alarm devices inside the sled, and can achieve all the functions of a fixed LNG refueling station. It is usually used as a temporary or semi permanent refueling station. Mobile LNG refueling stations are generally equipped with single pump single machine configuration or single pump dual machine configuration.
