Beschreibung
Zusammenfassung:	The invention relates to a method for separating solvents consisting of halogenated hydrocarbons with a low molecular weight, from oil-containing solutions and suspensions, during the production of lubricating oil, by means of a solvent-resistant, selective nanofiltration membrane consisting of polyamide imide. The separation process is carried out at temperatures of between 100 and -30 DEG C, with an overflow speed of between 0.5 and 10 m/s, and the transmembrane pressure difference between the inflow side and the permeate side is between 1 and 50 bar. The solvent consists essentially of a mixture of dichloromethane and dichloroethane.
