Abstract
: The article deals with the possibilities of regenerating operating fluids, assessing the composition of new, used, and regenerated oils by evaluating their toxicity and proposing the environmentally friendly regeneration method. The focus lies on two methods of regeneration of waste operating fluids: distillation and electrostatic cleaning. Oil samples, regenerated through these methods, were analyzed using gas chromatography with mass detection. The variance in composition among new, used, and regenerated oils depends on the method of regeneration. Properties of hydrocarbons exhibiting ecotoxic, mutagenic, teratogenic, carcinogenic, and other effects were identified using safety data sheets and databases like Pubchem, ChemicalBook. Analyzing HLP 46 oil (samples of new, unused, used and regenerated oil) revealed that the most toxic hydrocarbons (acetane, heptacosane, nonacosane) were absent after regeneration through electrostatic cleaning. Comparing the composition of operating fluids before and after regeneration, it was established that the most environmentally favorable regeneration method is electrostatic cleaning, which maintains the original properties of the operating fluids intended for use. Operating fluids regenerated
期刊介绍:
Archives of Environmental Protection is the oldest Polish scientific journal of international scope that publishes articles on engineering and environmental protection. The quarterly has been published by the Institute of Environmental Engineering, Polish Academy of Sciences since 1975. The journal has served as a forum for the exchange of views and ideas among scientists. It has become part of scientific life in Poland and abroad. The quarterly publishes the results of research and scientific inquiries by best specialists hereby becoming an important pillar of science. The journal facilitates better understanding of environmental risks to humans and ecosystems and it also shows the methods for their analysis as well as trends in the search of effective solutions to minimize these risks.
