A method for the production of glycol recyclates by physicochemical processing of antifreeze waste fluids

摘要

The dynamic development of pro-ecological sources of energy, including solar energy systems and heat pumps, generates a need for the development of specialised antifreeze fluids with relevant utility properties, high ecological potential, and an affordable price. The article presents a method for obtaining high quality glycol recyclates in the course of the physicochemical treatment of antifreeze fluids removed from use. The study investigated samples of fluids that underwent a series of treatments applied in an experimental system carrying out filtration, sorption,and radiation disinfection. The glycol recyclates were subjected to spectral analysis, and their physicochemical properties were measured, which are decisive in determining the fluid's practical usefulness. The study established that the physicochemical treatment results in high quality products that can be used as substitutes for new antifreeze hydro-glycol components in green energy systems.
