The reciprocating compressor units with a wide pressure and capacity range are used in CNG stations. The compressor unit is responsible for the compression process of the natural gas.
The low-pressure gas treatment unit is designed for purification and adsorption dehydration of gas at the inlet to the compressor unit.
The high-pressure gas treatment (drying) unit is designed to reduce the moisture content of the natural gas passing through it and to remove mechanical impurities.
CNG storage system is designed to store compressed natural gas, quickly refuel natural gas vehicles and reduce the number of compressor unit starts.
CNG dispensers are designed to fill cylinders of motor vehicle fuel systems, mobile gas refuellers and cassette assemblies with compressed natural gas.
Intake valves module is designed to supply and automatically shut off gas to the compressor unit with discharge to the gas flare. The module can be equipped with a custody transfer meter (optional).
Automatic control system is used to control the compressor unit according to a pre-set algorithm, to monitor parameters, to protect the compressor unit against emergency operating conditions, and to communicate its status to a superordinate level.
Automatic control system (for CNG station) is an information and control system that controls all the process equipment of the CNG station and its auxiliary mechanisms.
Priority panel is designed to control the sequence of filling sections of the gas-charged accumulator unit in a certain order with subsequent gas supply to the CNG dispensers.
The process containerised module is designed to house the process equipment in order to protect it from precipitation and ensure operation at low ambient temperatures.
Compressed natural gas (CNG) stations are designed for refuelling motor vehicles with compressed natural gas.
Depending on the availability of a gas pipeline and the possibility of connecting to a pipeline, CNG stations are divided into
A classically designed CNG station consists of process equipment units housed in one or more containers. A prerequisite for such a CNG station is the existence of a gas distribution pipeline. The classic CNG station is suitable for refuelling cars, trucks, buses, agricultural machinery, mobile gas refuellers and other types of CNG vehicles. The classic CNG station is fixed-mounted.
In the absence of a gas pipeline, gas is supplied to the CNG substation via a mobile gas refuelling vehicle, which is refuelled at the classic “parent” CNG station.
The advantage of a CNG substation is its mobility. It is capable of supplying CNG not only to on-site transport, but also to remote vehicle depots and other facilities where no gas pipeline is available.
Compressed natural gas (CNG) is a compressed form of methane that is used as a vehicle fuel in place of gasoline, diesel fuel and liquefied autogas (LPG).
Compressed natural gas (CNG) is the only motor fuel that can be produced directly on site.
The key benefits of in-house CNG production are
