The Factors of Triethylene Glycol Contaminated and Recycling Methods

Triethylene glycol is commonly used as dehydrating agent in natural gas dehydration process,but Triethylene glycol turned bad easily in the process of dehydration,which affects the dehydration effect then. This article analyzes the factors of triethylene glycol contaminated,determining abandonment indexes and studying the method of purification when processing the abandoned triethylene glycol. Thus the triethylene glycol waste can be recycled, reducing production costs.
