SOx METHOD FOR REMOVING SOx FROM GAS WITH COMPOUND ALCOHOL-AMINE SOLUTION

摘要

The present invention provides a method for removing SO _x in a gas with a mixed alcohol amine solution. Ethylene glycol and / or polyethylene glycol is mixed with a hydroxyl group and / or a carboxyl group organic compound having a nitrogen-containing basic group to prepare a solution of a mixed alcohol amine solution, and the solution of the mixed alcohol amine is brought into contact with a gas containing SO _x , SO _x , where x = 2 and / or x = 3. Complex alcohol amine solution has absorbed SO _x is a heating method, a vacuum method, stripping method, an ultrasonic method, a microwave method, and is regenerated using one or more of the methods of spinning, to produce a by-product of the sulfur dioxide and sulfur trioxide, the complex after regeneration Alcohol amine solutions are used in circulation. The process can be used to remove SO _x from flue gases, combustion gases, coke oven gas, dye factory synthetic waste gas, chemical fiber factory exhaust pollutant gases, and other industrial feedstocks containing SO _x or waste gas.
