Buffer Tanks
General Description
The natural gas pressure in the pipeline of CNG station is usually fluctuating in a certain range, while the pressure-fluctuating gas may affect the lifetime of compressor’s accessories including inlet and outlet valve. Therefore, it is really necessary to adopt a pressure buffer tank to make the natural gas in a stable condition before it is sent into the compressor and dehydration equipments. The volume of buffer tank is about 2m3-5m3.
