Zusammenfassung:	The process of getting petroleum ceresins by deoiling residual dewaxing raffinates with solvents was investigated. The relationships between the key ceresin quality and deoiling process parameters, such as composition and solvent to feedstock ratio, final cooling and filtration temperatures, and number of deoiling stages were determined. The influence of the increase in deoiling stages on the key quality characteristics and the yield of petroleum ceresins is shown.
