Abstract

The influence of the solvent’s new polar component on the dewaxing process of oil raffinates by the method of extractive crystallization using a cyclohexanone – toluene composition as a solvent was studied. It has been found that when using a new solvent, the separation of the oil raffinate into dewaxed and slack wax is more selective in comparison with the industrial solvent acetone – toluene. As a result, the yield of dewaxing product increases, and the content of solid paraffinic hydrocarbons in the gache increases.
