Working Principle

The CNG pressure reducing skid adopts a dual inlet configuration, one open and one standby. Each route is independent of each other and can work simultaneously when necessary. Each route has two-stage pressure reduction and two-stage heat exchange, and the two-stage pressure reduction ensures reasonable and stable distribution, the two-stage heat exchange ensures that the temperature of compressed natural gas is around 5°C during the pressure reduction process. The equipment inlet pressure is 20MPa, the first-stage outlet pressure is 0.8-1.6Mpa, and the second-stage outlet pressure is 0.1-0.4Mpa. Since the working pressure of the CNG pressure reducing skid is high and the pressure variation range is large, the equipment and pipeline layout in the skid are strictly required; the performance requirements of the pressure reducing device, metering device and various valves are high to ensure the safety of the system.
