Abstract:
The present invention relates to a method for running natural gas powered combustion systems, such as an internal combustion engine, a furnace, a fired heater, a power plant, an incinerator, and the like. In one embodiment of the present method, heavier hydrocarbons are separated from a natural gas feedstream in a PSA unit to provide the light hydrocarbon gas stream which is combined with an ethane plus tail gas stream from a liquefaction unit to fuel the combustion system. This method eliminates flaring any gas and minimizes the size requirements for the PSA unit.
Abstract:
The present invention relates to a method to remove one or more contaminant from a gas stream, preferably a hydrocarbon gas steam, using a solid adsorbent, preferably a porous cross-linked polymeric adsorbent, a pyrolized macroporous polymer, or mixtures thereof and regenerating said adsorbent by an improved pressure swing adsorption process wherein a portion of the product gas is heated and used as the purge gas.
