Abstract
A method for processing pre-combustion syngas includes, in an exemplary embodiment, providing an absorber unit having a membrane contactor having a plurality of micro-pores, channeling pre-combustion syngas along a first surface of the membrane contactor, channeling an amine based solvent along a second opposing surface of the membrane contactor, 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 micro-pores in the membrane contactor, to separate CO2 from the flue gas by a chemical absorption of CO2 into the solvent to produce a solvent containing CO2.

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 CO2 from the syngas by a chemical absorption of CO2 into the solvent to produce a solvent containing CO2.
A pre-combustion syngas processing apparatus comprising an absorber unit, said absorber unit comprising:
- a housing comprising an inlet chamber, an outlet chamber downstream from said inlet chamber, and a solvent chamber therebetween, said solvent chamber is configured to contain a solvent therein;
- a plurality of membrane contactors positioned substantially parallel to each other in said housing such that each of said membrane contactors extend from said inlet chamber through said solvent chamber to said outlet chamber;
- and
- a syngas area within said housing, said syngas area containing pre-combustion syngas, said membrane contactors separating said solvent from said syngas, each of said membrane contactors comprising a plurality of micro-pores defining gas-liquid interface areas to separate CO2 from the syngas by a chemical absorption of the CO2 into said solvent.
