Method for removing SOx from gas using ethylene glycol composite solution
An ethylene glycol composite solution is used for removing SOx from a gas. The ethylene glycol composite solution is made by mixing ethylene glycol and/or polyethylene glycol with an organic acid and/or organic acid salt containing no nitrogen atom in a molecule. The ethylene glycol composite solution is brought into contact with the gas containing SOx to absorb the SOx in the gas. The ethylene glycol composite solution loaded with absorbed SOx is regenerated by heating, vacuuming, gas stripping, ultrasonic treatment, microwave treatment, or radiation treatment to release by-products of sulfur dioxide and sulfur trioxide, and the regenerated ethylene glycol composite solution is recycled for use.
