Abstract: A method of recycling solar panels, including a frame, glass, silicon wafers, and wiring, incorporates the steps of: (a) delaminating the solar panel by breaking down ethylene-vinyl acetate polymer in the solar panel to generate fumed acetic acid, (b) dissolving silver from the silicon wafers of the solar panel in a metal recovery solution using the fumed acetic acid generated during the delaminating and (c) recovering the dissolved silver from the metal recovery solution.

Abstract: A packing for gas separation from a liquid absorbent includes a body having a corrugated surface or surface sub-texture adapted to create local turbulence within a liquid absorbent with which the body has been wetted. The body may also has a corrugated profile wherein the surface sub-texture comprises a plurality of individual scallops and the corrugated profile comprises a plurality of individual furrow with between about 2 and about 50 individual scallops per furrow. The packing is useful in a method for gas separation from a liquid absorbent.

Abstract: An apparatus for removing an acid gas from a feed gas stream includes an absorber and an electrochemical regenerator. The absorber is adapted for separating the acid gas from the feed gas feed stream using a lean carbon capture solvent. The electrochemical regenerator is connected to the absorber and adapted for (a) regenerating the carbon capture solvent and (b) generating hydrogen gas. A method for removing acid gas from a feed gas stream includes steps of separating, delivering, releasing, generating and returning.

Abstract: An air preheater for a solid fuel-fired power plant includes a housing, a regenerative heating element received in the housing and adapted to transfer heat from the flue gas stream to the air stream, a plurality of flow control valves upstream of the regenerative heating element and a controller adapted to selectively open and close each valve of the plurality of flow control valves in order to provide an air flow shadow extending downstream over a selected portion of the regenerative heating element whereby ammonium bisulfate previously deposited on the selected portion is decomposed to loose dry ash. A method of decomposing and removing ammonium bisulfate from a regenerative heating element is also presented.
