1. The selection of CNG gas compressors and the number of natural gas compressors should be determined according to the inlet pressure of the gas filling station, the discharge pressure of the outlet, the total gas filling capacity and the working characteristics of gas filling. The parent gas refueling station also needs to set up a spare CNG gas compressor, and the gas refueling sub-station should be equipped with a small compressor for pour gas.
2. The CNG gas compressor power machine should use an electric motor or natural gas engine.
3. A buffer tank should be installed in front of the CNG gas compressor.
4. When installing the suction, discharge and exhaust pipes of the compressor unit, the vibration of the pipes should be avoided to cause harmful effects on buildings and structures.
5. The CNG gas compressor should be arranged in a single row, and the width of the main passage of the compressor room should not be less than 2m.
6. The operation and management of the CNG gas compressor unit should adopt centralized computer control.
1. A safety valve should be installed between the outlet of the CNG gas compressor and the first shutoff valve. The discharge capacity of the safety valve should not be less than the safe discharge capacity of the compressor.
2. The compressor inlet and outlet should be equipped with high and low pressure alarms and high pressure over-limit shutdown devices.
3. The cooling system of the compressor unit should be equipped with a temperature alarm and shutdown device.
4. The lubricating oil system of the compressor unit should be equipped with a low-pressure alarm and shutdown device.
5. The unloading exhaust of the compressor shall not be vented to the outside. The recovered natural gas can be transported to the inlet buffer tank of the CNG gas compressor.
6. The condensate discharged from the compressor should be treated collectively.
