FIELD: chemistry.SUBSTANCE: invention can be used in production of potassium chloride using a halurgic method. Method for controlling said process involves controlling flow of water into the solution for crystallization depending on the concentration of potassium chloride and its temperature. Flow of solution and crystalline sodium chloride and magnesium chloride content are measured. Flow of water into the solution for crystallization is calculated according to the obtained parameters. Calculated values is loaded in solution consumption control system as a setting point.EFFECT: invention simplifies the process due to supply of cyclone dust solution into intake tank of the vacuum-crystallization installation (VCI) for dissolution of crystalline sodium chloride, contained in the hot clarified saturated solution, redistribution of water consumption for VCI, taking into account impurities, and increased calculations reliability.1 cl, 8 tbl, 4 ex |
