Methods and apparatus relate to recovery of carbon dioxide and/or hydrogen sulfide from a gas mixture. Separating of the carbon dioxide, for example, from the gas mixture utilizes a liquid sorbent for the carbon dioxide. The liquid sorbent contacts the gas mixture for transfer of the carbon dioxide from the gas mixture to the liquid sorbent. Contacting of the sorbent with the gas mixture and/or desorption of the carbon dioxide from the liquid sorbent utilize hollow fiber contactors that have permeable walls and incorporate particles distinct from a remainder of the walls to influence wetting properties of the contactors. Polytetrafluoroethylene particles may be homogenously disposed throughout hollow fiber contactors to influence wetting properties of the contactors.

Fluorinated surfactants and stabilization of polytetrafluoroethylene (PTFE) particles in hollow fiber spin solutions

A process of mixing methyldiethanolamine to water to produce a first mixture. 2-amino-2-methyl-1-propanol is added to the first mixture to form a second mixture. The second mixture is then heated while mixing to form a third mixture. Piperazine is then added to the third mixture to form a solvent.
