Abstract
A membrane contactor system for use in separating carbon dioxide from a gaseous stream in a continuous flow process comprising a housing defining a gas flow path and comprising a first outlet for the carbon dioxide and a second outlet for the purified gas; an expanded polytetrafluoroethylene microporous membrane positioned in the housing to allow the gaseous stream to flow across a side of the expanded polytetrafluoroethylene microporous membrane, the membrane having a plurality of interconnecting pores configured to allow the carbon dioxide to diffuse therethrough; an oleophobic enhancement coating disposed on the surfaces to form a coated membrane; and an amine based sorbent liquid disposed on a side of the expanded polytetrafluoroethylene microporous membrane opposite the gas, wherein the amine based sorbent liquid is configured to absorb the carbon dioxide from the gaseous stream.
