One of the ways of efficient use of waste motor oils is their recovery, i.e., purification and recovery of performance properties for further reuse. It not only saves petroleum products but also reduces their negative impact on the environment. The performed analysis showed that there is no optimal procedure for evaluation of the selectable waste oil recovery technologies at the present time. The experience of optimization of energotechnological systems has shown great value of thermodynamic methods of analysis which allow finding optimal schemes and parameters of the recovery process on the basis of thermodynamic relations using simpler but at the same time more precise methods. Searching for the best options of energotechnological schemes of recovery units on the basis of the thermodynamic effectiveness indexes allows, in most cases, obtaining necessary information about its energy efficiency. At the same time, the most advanced basis for performing such analysis and optimization is an exergy concept resulting from the second law of thermodynamics The exergy analysis method allows evaluating the degree of utilization of energy, its losses, as well as obtaining energy-loss distribution over separate devices of the system and finding the least effective ones. The suggested procedure of thermodynamic optimization allows reliably selecting such a method for the recovery of waste oils from many suggested ones which provides the maximum saving of energy resources, and the exergy analysis allows objectively evaluating the practicability of the recovery of waste motor oils.
