Concentration of magnesium chloride solution in experimental equipment with a descending film

  • Published:
Chemical and Petroleum Engineering Aims and scope

The aim of the work is determination of production temperature and salt regimes for an industrial three-vessel vacuum evaporation unit for concentrating magnesium chloride solution, included within technology for artificial carnallite preparation. A scheme is provided, and a unit developed and manufactured for this purpose is described. Experimental data are provided that were obtained during magnesium chloride solution concentration within a single-tube evaporation unit with a descending film (unit) under different regimes. A distribution device is selected for provision of stable film flow over the inner surface of a heat-exchange tube. The possibility is confirmed by experiment for the first time of using equipment with a descending film for concentrating actual magnesium chloride solution. Data are obtained for the limiting salt content within the concentrated solution providing operation of the unit in a crystallization-free regime.
