  • Process for separating acid gases from gaseous mixtures utilizing composite membranes formed from salt-polymer blends
    Patent number: 6315968
    Abstract: The present invention is a process for separating acid gas from gaseous mixtures containing acid gas and at least one non-acid gas. The process comprises bringing the gas stream into contact with a multilayer composite membrane comprising a non-selective polymeric support layer and a separating layer comprising a blend of a water soluble polymer and one-half equivalent or more of an acid gas reactive salt based upon the repeating unit of the water soluble polymer, the acid gas reactive salt which is formed from a monovalent cation and an anion for which the pKa of the conjugate acid is greater than 3, wherein the multilayer composite membrane separates the acid gas from the gaseous mixture by selectively permeating the acid gas.
