摘要

A new process for used oil treatment was investigated, which uses compressed propane for the extraction of the oily fractions. It is demonstrated, that it is possible to clean used oils in compact plants at moderate pressures lower than 100 bar and with low energy consumption. The process is realised in a pilot plant with a capacity of up to 40kg/h of used oil. The gained product has a quality which allows its use in small local diesel driven power plants. If the extraction is combined in an integrated process with hydro-treatment in presence of propane even an oil quality is obtained, that is applicable as base oil for lubricants, Thermodynamic studies and integrated processes are presented which illustrate how the used oils have to be treated to get clean oils of high quality at a high yield.
