Method for removing SOx in gas with modified polyethylene glycol solution

摘要

The present invention is a method of removing SOx in a gas, and is a method of absorbing SOx (x = 2 and / or 3) in a gas with a modified polyethylene glycol solution. To make SOx in the gas absorbed. Modified polyethylene glycol is a product obtained by etherifying a hydroxy group in ethylene glycol and / or polyethylene glycol molecules, the general formula is R1- (O-C2H4) nO-R2, and n is a positive integer. R1 and R2 may be the same or different and each independently represents an alkyl, alkenyl, alkynyl, acyl or aryl group.
