|Description:||The possibility of paraffin wax separation from the high-boiling slack wax by static crystallization has been studied. Gas chromatographic analysis of individual hydrocarbon composition of the high boiling slack wax and its structural-group compos ition by the method of IR Fourier spectroscopy has been determined, experiments on the de-oiling on installation that simulates the operation of industrial crystallizers has been done. It is established that the de-oiling process of the high-boiling slack wax by static crystallization is obtained tightened in time and economically impractical. It has been proposed to introduce the paraffin oil from low-boiling slack wax as a diluent for the high boiling slack. Physical and chemical analysis of individual raw material components and their mixtures has been determined, the process of de-oiling by static crystallization has been done. The introduction of the paraffin oil from low-boiling slack wax into the high-boiling slack wax reduces the time and the temperature of partial melting phase of static crystallization without worsening the quality of the melt. As a result, the static crystallization goes faster and different technological costs are reduced.|
