Method for removing SOx from gas using modified polyethylene glycol

摘要

A method for removing SOx from a gas using a modified polyethylene glycol solution to absorb the SOx in the gas. The modified polyethylene glycol solution contacts the gas containing SOx and absorbs the SOx in the gas, x being 2 and/or 3. The modified polyethylene glycol is the product of etherification of the hydroxyl in ethylene glycol and/or polyethylene glycol molecules, and has the formula of: R
