Method for removing SOx from gas using polyethylene glycol

x x x A method for removing SO(x=2 and/or 3) from gas using a solution having polyethylene glycol as the main ingredient. First, SOin the gas is absorbed by the solution of polyethylene glycol. Second, the solution of polyethylene glycol which has absorbed SOis regenerated by one or more of the heating, vacuum, ultrasonic, microwave or radiation methods, thereby releasing the by-products of sulfur dioxide and sulfur trioxide. The regenerated solution of polyethylene glycol is recycled. When the water content of the regenerated solution of polyethylene glycol is high enough to affect the desulfurization, it needs to be removed. Removal methods include heating and rectification, absorption using a water absorbent, or a combination of these methods. The polyethylene glycol solution is recycled after dehydration.
