Abstract: The article describes a new design of disc scraping regenerative crystallizer for dewaxing oils and de-oiling slack waxes and petrolatums. To study heat transfer in the crystallizer of this design a computer model of one section of the unit was built. The problem of conjugate heat transfer was solved in a specialized software package based on the numerical finite volume method. The results of numerical simulations, the comparison of the data provided by the developers of the disk crystallizer are presented. The study results showed that the proposed model adequately describes the hydro- and thermodynamic modes of the commercial crystallizer.
