Abstract:

The major equipments about LNG/L-CNG filling stations were introduced, including LNG storage tanks, LNG submersible pump, unloading supercharger, EAG heater, LNG high-pressure piston pump, high-pressure gasifier, CNG gas cylinders, dispensers, sequence control panel and so on. The calculation method of above equipments selection in the process of designing was also introduced. Problems like piping stress compensation,selection of pipe and fittings materials, selection of heat insulation structure and materials should be noticed in the design.
