Removal of sulfur dioxide and/or trioxide from gaseous effluents of fossil fuel operated power and steam plants

摘要

This invention relates to the removal of sulfur dioxide (SO2) and/or sulfur trioxide (SO3) from the gaseous effluents of fossil fuel burning steam and power plants using certain macroreticular, weak acid, cation exchange resins. The gaseous streams to be treated may be derived from other sources but the invention has particular utility and applicability in the control of pollution emanating from the SO2 and SO3 contained in the gaseous effluents of fossil fuel burning steam and power plants.
