Production of mineral lubricating oils from filtrate of paraffin wax production by hydrofining

Conclusions Hydrofining the filtrate from paraffin-wax production of Ozeksuatsk crude yielded a number of industrial lubricants and also transformer oil meeting the requirements of GOST 982-56.The by-products of hydrogenation, gasoline and diesel fuel fractions, can be used as components of commercial automotive gasolines and diesel fuels.The yield of transformer oil and paraffin wax obtained from filtrate by deep solvent dewaxing is significantly higher than by urea dewaxing.After deoiling and refining, paraffin wax separated from the filtrate by urea dewaxing can be used as feed-stock for petrochemicals synthesis, as it contains a high proportion of hydrocarbons that form complexes and the oil content is low.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 2, pp. 23–25, February, 1970.
