Embodiment Construction

[0006]One or more aspects of the present disclosure provides an economic home refueling system (HRS) that allows consumers to realize the economic and convenience benefits of NGV vehicles and at-home refueling. One or more aspects of the present disclosure provides a commercial refueling system.

[0007]One aspect of the present disclosure relates to a gas compression system configured to compress gas. In some embodiments, the gas is natural gas. The system comprises one or more each of a first stage compressor, a second stage compressor, a hydraulic pump, and / or other components. Each stage of compression may be accomplished through the use of compressors either in series or in parallel. Hydraulic pumps may also be used in series or parallel to achieve desired hydraulic flow rates. The first stage compressor(s) is configured to compress the gas to a first pressure level and provide the gas for the second stage compressor(s) at the first pressure level. The second stage compressor(s) i...

Abstract

A refueling system for natural gas users (e.g., natural gas vehicles) includes a two-stage compression system that compresses low-pressure gas in a natural gas supply line to compressed natural gas (CNG) pressure for use by a user. A single motor drives both a first stage rotary compressor and a rotary hydraulic pump that powers a second-stage liquid piston compressor. The motor, first stage compressor, and pump may be co-axially aligned. Booster vessels store compressed gas to augment the system's compressed gas delivery flow rate when desired. The booster vessels may be recharged with compressed gas when the system is not delivering gas to a user. Hydraulic liquid may be pumped into and out of the booster vessels during booster vessel discharge and recharge, respectively, to maintain a desired pressure within the vessels.

Description

CROSS REFERENCE[0001]This application claims the benefit of priority from U.S. Provisional Application No. 61 / 783,781, filed Mar. 14, 2013, titled “Natural Gas Home Refueling System,” the entire contents of which are hereby incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure relates to a home refueling gas compression system and method for use with natural gas vehicles (NGV).[0004]2. Description of Related Art[0005]Currently, NGV infrastructure is lacking due to the high capital costs associated with construction of public NGV filling stations. Typical gas compression systems are physically too large and / or expensive to operate in a normal home.SUMMARY OF EMBODIMENTS OF THE INVENTION[0006]One or more aspects of the present disclosure provides an economic home refueling system (HRS) that allows consumers to realize the economic and convenience benefits of NGV vehicles and at-home refueling. One or more aspects of the...
