The paper presents the research of the process of recovery of used motor oil to be applicable for construction machinery. The solution to the problem in question consists in the development of compact oil recovery facilities to be installed in the areas where used oil is generated. Their concept of operation consists in the employment of baromembrane liquid separation principle. It is characterized by low power consumption, as the separation of used oil from admixtures may be performed within the temperature range of 20 to 40°C. The following conclusions were made upon completion of the research project: used motor oils may be applied for recovery purposes through the application of membranes, with dimensions of pores varying from 0.15 to 0.5 mcm; the optimal filtering pressure is to vary between 0.3 and 0.5 MPa; any further research is to cover the problem of periodicity of maintenance of membranes aimed at the restoration of their performance and selectivity within a particular service period. Depending on the type of membranes and the degree of used oil treatment, recovered oil may be applied for the initially designated purpose, as an additive injected into diesel fuel or delivered to major oil recovery facilities, although the latter purpose requires preliminary improvement of physical and chemical properties of used oil to assure its complete recovery.
