Patent ID: 7442239

Claim:
A fuel-conditioning skid for an engine, the fuel-conditioning skid comprising: an inlet connectable to a source to receive a flow of gaseous fuel containing undesirable compounds; an outlet connectable to the engine to deliver a flow of fuel that is substantially free of undesirable compounds; an inlet cleaner in fluid communication with the inlet and operable to remove a portion of the undesirable compounds; a compressor in fluid communication with the inlet cleaner, the compressor receiving the flow of fuel at a first pressure and discharging the flow of fuel at a second pressure, the second pressure being greater than the first pressure; and a purifier in fluid communication with the inlet cleaner to receive the flow of fuel, the purifier operable to chill out the flow of fuel to a temperature below the freezing point of water to condense out and remove at least a portion of the remaining undesirable compounds from the flow of fuel.
