Reciprocating compressor with high pressure storage vessel let down for CNG station and refueling motor vehicles

摘要

Embodiments of the present invention are directed toward a reciprocating compressor having a high pressure storage vessel let down for a CNG station for refueling motor vehicles, wherein the CNG station design utilizes inlet gas from a local gas utility. By supplementing the inlet gas with a pressure let down in order to de-pressurize the gas from a high-pressure storage vessel, the CNG station has the ability to increase and adjust its flow capacity.

主权项

1. A system, comprising:
a gas inlet section including an inlet gas meter for metering inlet gas from a high pressure storage vessel; a compressor section; a valve control panel and storage section; a pressure let down section comprising multi-stage depressurization regulators, pressure transducers, and gauges to monitor its operation, wherein the pressure let down section depressurizes the high pressure gas from the high pressure storage vessel to the inlet of the compressor section, thereby increasing the flow capacity of the system and providing the ability to increase and adjust its flow capacity; and a dispensing section.
