Patent number: 9017454Abstract: A method for removing SOx (x=2 and/or 3) from gas using a solution having polyethylene glycol as the main ingredient. First, SOx in the gas is absorbed by the solution of polyethylene glycol. Second, the solution of polyethylene glycol which has absorbed SOx is 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.Type: GrantFiled: February 10, 2010Date of Patent: April 28, 2015Assignees: Beijing Boyuan-Hengsheng High-Technology Co., Ltd., Yongfeng Boyuan Industry Co. Ltd., Peking UniversityInventors: Xionghui Wei, Fang Han, Jianbin Zhang, Pengyan Zhang, Daolong Gao, Jinfei Wang, Chuan Zou, Chun Hu
