Abstract

Настоящее изобретение относится к способу получения хлорида натрия и хлорида кальция путем регенерации отходов, образованных по завершении осуществления способа Сольве. Таким образом, при наличии плоского и подходящего поля или соленого озера вблизи завода по производству кальцинированной соды, посредством производственных бассейнов, которые необходимо создать в данном поле или озере (аналогично способу получения твердой соли за счет соленых озер), слабый раствор испаряется до определенной концентрации, сначала кристаллизуется NaCl, а затем CaCl2, в соответствии с различием в степени растворимости, и после этого твердые CaCl2 и NaCl, находящиеся в бассейне, доставляют с помощью скребковой машины на участок для хранения продукта, при этом реализация полученных продуктов потребителям предусматривается в течение одного года. Посредством данного способа продукт получают раз в год, и его хранение и продажа могут быть реализованы в течение года.The present invention relates to a process for the production of sodium chloride and calcium chloride by the recovery of waste generated after the completion of the Solvay process. Thus, in the presence of a flat and suitable field or salt lake near the soda ash plant, by means of production pools that need to be created in this field or lake (similar to the method of obtaining solid salt from salt lakes), a weak solution evaporates to a certain concentration, first, NaCl crystallizes, and then CaCl2, in accordance with the difference in the degree of solubility, and after that, the solid CaCl2 and NaCl in the pool are delivered by a scraper machine to the storage area, while the products obtained will be sold to consumers within one year ... By this method, the product is obtained once a year, and its storage and sale can be realized throughout the year.
