A Method for the Production of Glycol Recyclates by Physicochemical Processing of Antifreeze Waste Fluids

Abstract:

Antifreeze glycol-based fluids are widely used in various types of industrial systems, equipped with indirect heat exchange systems. A very broad area of the application of glycol fluids is possible due to their primary physicochemical properties, i.e. relatively high boiling point, very low freezing point, and negligible thermal expansion [1,2]. Examples of the application of these fluids may be, e.g. cooling systems and air conditioning, in which glycol fluid is the heat transferring agent [3 – 5].
