Distillation and Crystallization Processes

Current activity


Laboratory researches and design works in the following fields:

  • the use of distillation and rectification operations in purifying of substances as well as in dividing technological streams; modelling of the continuous and periodic systems, especially the azeotropic ones;
  • the computer aided designing of the industrial installations, especially rectifying columns and heat exchangers using simulating programs in ChemCAD software package;
  • optimization of based on distillation processes technological lines using simulating package ChemCAD;
  • the use of the melt crystallization (from the solid state) as a method of purifying of the chemical substances.

Additional works in the following fields:

  • determination of definite physicochemical properties of the pure substances and process streams;
  • prediction of the substance physicochemical properties;
  • gathering of the reliable physicochemical data for the institutional technological purposes;
  • correlating of the experimental data (VP, VLE) by recommended equations and thermodynamic models;
  • development of the corporate Physicochemical Properties Data Bank which are available in the Intranet network.
