Goal and object’s purpose: construction of new technological line for production of coarse crystalline halurgical potassium chloride with output of at least 1,500,000 tons per year.
Method of production: potassium chloride vacuum-crystallization from hot saturated liquors. Selected process of obtaining coarse crystalline of potassium chloride consists of stepwise liquor evaporation under the vacuum in installation, consisting of seven evaporates. For the purpose of maximum energy efficiency in installation the recovery of thermal energy is provided by cooling of mother liquor with a help of titanium surface heat exchangers and mixing condensers. To reduce foaming the installation equipped with automated preparation and dozing system of antifoam agent.
Final product: coarse crystalline potassium chloride, chemical formula – KCl, average size of cluster crystals of round shape dcp=0,6 – 0,8 mm. The production of coarse crystalline potassium chloride with useful component content in conversion to К₂О not less than 62,0%.
