METHOD OF BT-301 SYNTHETIC OIL RECOVERY

FIELD: chemical industry; methods of the synthetic oils recovery. ^ SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to the method of -301 synthetic oil recovery and may be used for an oil recovery of the -301 synthetic oil applied in the heat-stressed gas-turbine engines. Substance: the method provides, that the oil is fed onto the filter with the porosity of 5-10 microns for separation from the mechanical impurities and then onto the filter with the microfiltration diaphragm with the porosity of 0.9-2 microns for filtration from the fine-dispersed gel-like particles. In the container used for the recovered synthetic oil they form the vacuum from 104 Pa up to 102 Pa. The filters are arranged one above other and rest on the metallic plate with the holes and are disposed between the tanks for the dirty oil and recovered oil, connected among themselves hermetically. The technical result of the invention is provision of the high-degree of the synthetic oil purification, that enables its reusage in the heat-stressed gas-turbine engines. ^ EFFECT: the invention ensures provision of the high-degree of the synthetic oil purification, that enables its reusage in the heat-stressed gas-turbine engines. ^ 1 dwg
