CNG Refueling Station (Including: CNG Standard Station, CNG Mother Station, CNG Daughter Station)

CNG Standard Station：It directly extracts gas from urban medium-pressure natural gas pipelines. After desulfurization, dehydration and compression, natural gas is stored in cylinder groups and supplied to CNG vehicles via dispensers.

Core equipment includes pressure regulating & metering skid, dehydration skid, natural gas compressors, gas storage cylinder groups and station control system.

CNG Mother Station: Constructed adjacent to natural gas pipelines or gate stations. It receives pipeline natural gas, then conducts purification, dehydration and compression to fill CNG tube trailers for gas transportation to daughter stations.

Core equipment includes pressure regulating & metering skid, dehydration skid, mother station compressors, filling columns and station control system (gas storage cylinder groups and dispensers are optional.

CNG Daughter Station: A refueling facility that adopts CNG tube trailers as gas sources to provide refueling service for CNG vehicles.

Core equipment includes CNG tube trailers, daughter station compressors, unloading columns, gas storage cylinder groups, dispensers and station control system.

Special facility for supplying liquefied natural gas fuel to LNG vehicles. Core equipment includes LNG storage tanks, cryogenic pump skids, LNG dispensers, tank vaporizers, unloading vaporizers, EAG heaters and station control system.

The facility vaporizes LNG on-site into CNG to provide refueling service for CNG vehicles, integrating LNG storage and CNG refueling functions organically. Core equipment includes LNG storage tanks, tank pressurization skids, unloading pressurization skids, high-pressure plunger pump skids, high-pressure vaporizer skids, water bath reheaters, sequence control panels, gas storage cylinder groups, CNG dispensers, EAG heaters and station control system.

Gas supply facility for receiving, storing and vaporizing LNG. It converts liquid natural gas into gaseous natural gas via vaporizers and delivers gas to pipeline networks. Core equipment includes LNG storage tanks, tank pressurization skids, unloading pressurization skids, ambient air vaporizers, water bath reheaters, pressure regulating & metering skids, EAG heaters and station control system.

The natural gas processing plant is a front-end purification facility for raw natural gas. It removes impurities such as free water, heavy hydrocarbons, hydrogen sulfide, carbon dioxide and mercury from wellhead crude gas through separation, filtration and purification processes, and produces qualified clean pipeline natural gas or raw material gas for LNG liquefaction.

The LNG liquefaction plant is a complete set of industrial equipment for natural gas liquefaction production. It takes purified clean natural gas as raw material, and produces low-temperature liquefied natural gas (-162 ℃) through refrigeration cycle and cryogenic liquefaction process, covering the whole process of raw gas pretreatment, liquefaction, storage and loading.
