Abstract:
1. A dual service system for use in compressing and dispensing pressurized gas, the system comprising: a methane gas source at an inlet pressure greater than atmospheric pressure; a hydrogen gas source at an inlet pressure greater than atmospheric pressure; a compressor having an inlet and an outlet, the inlet communicating selectively with the methane gas source, with the hydrogen gas source, and with both the methane gas source and the hydrogen gas source, and the outlet having a discharge pressure greater than the inlet pressure of the methane gas and hydrogen gas; valves selectively controlling the flow of methane gas and hydrogen gas to the compressor; a cooler in fluid communication with the compressor outlet, the cooler being operable at a gas pressure at least as great as the discharge pressure of the compressor; and a dispenser in downstream fluid communication with the cooler.
