Possibility of Regeneration of Used Low-Freezing Liquids

. International Journal of Discoveries and Innovations in Applied Sciences, 3 (5): 51-56 (May 2023)

Abstract

One of the reasons for frequent breakdowns of a car engine is its overheating, which is caused by the unsatisfactory state of low-freezing fluids, which must be changed in a timely manner, but every year thousands of tons of ethylene glycol are simply poured into the sewer. Ethylene glycol and its solutions are toxic. Compared to light petroleum products, they cause poisoning only when ingested. Therefore, studies on the regeneration of low-freezing liquids are appropriate and relevant from an environmental and economic point of view. There are various ways to regenerate low-freezing liquids, however, they are all very laborious and energy-consuming. The purpose of this work is to develop a method for the regeneration of low-freezing liquids with the maximum reduction in energy and labor costs.
