The possibility of producing semi-purified and deeply deoiled paraffins from slack waxes by the method of static crystallization is investigated. Optimal parameters of a one-stage deoiling process for obtaining semi-purified paraffins with an oil content of less than 3 wt% were determined. The potential of a two-stage deoiling process for production of deeply deoiled paraffins with an oil content of less than 1 wt% was demonstrated. The economic efficiency of the proposed methodology of slack wax deoiling by static crystallization was confirmed by calculations.
