LNG is short for Liquefied Natural Gas.
The LNG filling station fills LNG vehicles with LNG through cryogenic
pumps. It can also, at the same time, fill CNG vehicles after putting
on pressure with high-pressure liquid pump and vaporizing the gas with
vaporizers. Among these gas filling stations, besides the classic
filling stations, of which the devices are assembled into a complete
system on-site, there are also another kind, where the devices of the
filling station are integrated and installed onto one or more skids
previously in the factory, and function to refuel vehicles as well as
standard gas filling stations: this is what is called portable LNG
Portable LNG filling
station has many outstanding advantages, including safe, environmentally
friendly, energy-saving, covering small area, easy to install on-site,
rapid to construct, highly manoeuvrable, etc. It has a good developing
prospect as a type of gas filling station.
design idea of the portable LNG vehicle filling station is high
integration, convenient operation and easy maintenance, and meeting the
requirement of relative national technology norms. It is special gas
filling equipment to fill the LNG storage tank of vehicles with the LNG
of 1.2mPa in pressure, and -162℃ in temperature inside the LNG tank
through pipeline, cryogenic pump and filling machine, etc.
is generally composed of：LNG tank, LNG cryogenic pump, LNG pressure
regulating vaporizer, EAG heater, LNG gas filling machine, skid base,
pipelines, control system and corollary equipment, etc.
