Abstract

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.

Description

[0001] References to related applications [0002] This application claims the benefit of US Provisional Patent Application 61 / 353625, filed June 10, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to compressors for compressed natural gas (CNG) stations used to refuel motor vehicles, and more particularly to reciprocating compressors having a high pressure storage vessel that depressurizes the CNG station for supplying Motor vehicle refueling. Background technique [0004] Most conventional CNG plants are custom designed for specific site conditions and must operate within predetermined inlet pressure and flow ranges. These gas stations typically take a long time to build, and because they are designed to meet specific site conditions, the flow capacity is limited by the inlet pressure available from the local gas company. According to other known CNG designs, air inlet regulators ar...
