PROCESS TO REMOVE AND RECOVER SULFUR DIOXIDE |
| abstract |
PROCESSES TO REMOVE AND RECOVER SULFUR DIOXIDE AND SIMULTANEOUS REMOVAL PROCESS OF SULFUR DIOXIDE AND NO X These are processes for the selective removal of contaminants from effluent gases. More particularly, some embodiments of the present invention relate to the selective removal and recovery of sulfur dioxide from effluent gases in a sulfur dioxide absorption/desorption process using an aqueous buffered absorption solution comprising certain organic acids or weak inorganics or salts thereof, preferably certain polyprotic carboxylic acids or salts thereof, to selectively absorb sulfur dioxide from the effluent gas. Oxidation inhibitors can be used. The absorbed sulfur dioxide is subsequently extracted to regenerate the absorption solution and produce a gas enriched in sulfur dioxide content. Absorption solution regeneration can include an integrated sulfur dioxide extractor and heat pump system to provide improved energy efficiency. Other embodiments of the present invention relate to a process for simultaneous removal of sulfur dioxide and nitrogen oxides (NOx) from effluent gases and recovery of sulfur dioxide. The process (...). |
