Clean, safe and efficient methods and systems for utilizing thermolysis methods to process and recycle various waste sources containing per- and polyfluoroalkyl substances to safely remove fluorine and other hazardous materials are provided. The methods and systems beneficially convert waste sources into a Clean Fuel Gas and Char source providing safe, efficient, and cost-effective alternatives to the current buildup of such waste sources. Methods utilizing a multicomponent, energy-assisted, chemical reaction are provided.

Systems and processes for treating acid gas from a sour gas stream are provided. A chemical looping combustion (CLC) process is provided that uses CaCO.sub.3 to capture sulfur from the acid gas and produce CaSO.sub.4. An acid gas treatment unit may receive an acid gas from an acid gas removal unit and produce the CaSO.sub.4 and various gas and air streams for use in heat exchangers for steam production. The acid gas treatment unit may include a fuel reactor, an oxidizer reactor, and a calciner reactor. Another acid gas treatment unit may include a fuel reactor that includes the calciner function and an oxidizer reactor. A selective membrane module may be disposed between the sour gas stream and an acid gas removal unit to produce a H.sub.2S and CO.sub.2 permeate that is mixed with the acid gas stream provided to the acid gas treatment unit.
