Abstract:
1. A method for processing pre-combustion syngas, said method comprising: providing an absorber unit having a housing that includes an inlet chamber, an outlet chamber downstream from the inlet chamber, and a solvent chamber therebetween, wherein the solvent chamber contains a solvent therein, and the absorber unit also includes a plurality of membrane contactors that are positioned substantially parallel to each other in the housing such that each of the membrane contactors extend from the inlet chamber through the solvent chamber to the outlet chamber, wherein each of the membrane contactors comprises a plurality of micro-pores; channeling pre-combustion syngas along a first surface of each of the membrane contactors; channeling the solvent along a second opposing surface of each of the membrane contactors; and contacting the solvent with the syngas such that the solvent and the syngas contact at gas-liquid interface areas, defined by the plurality of pores in each of the membrane contactors, to separate CO
