Title: Methods and systems for treating a switchable polarity material, and related methods of liquid treatment

Abstract

A method of treating a switchable polarity material comprises introducing a first feed stream comprising a solvent and a non-polar form of the switchable polarity material to a first side of a gas diffusion membrane. A second feed stream comprising an acid gas is introduced to a second side of the gas diffusion membrane opposing the first side of the gas diffusion membrane. Molecules of the acid gas of the second feed stream are diffused across the gas diffusion membrane and into the first feed stream to form a product stream comprising a polar form of the switchable polarity material. A treatment system for a switchable polarity material, and a method of liquid treatment are also described.
