FUEL CONDITIONING PROCESS AND APPARATUS

摘要

A fuel conditioning process and apparatus for use where natural gas is compressed by a field compressor driven by a natural gas powered engine. The fuel portion of the compressed natural gas is passed through an adsorption bed capable of adsorbing impurities. The outlet gas from the adsorption bed is accumulated and mixed for averaging and controlling the heating value of the outlet gas as used for fuel. Regeneration of the adsorption bed is accomplished by connecting the adsorption bed to the suction side of the compressor, and purified gas from another adsorption bed in adsorption service is backflowed through the loaded adsorption bed to desorb the previously adsorbed impurities.
