PROSPECTS OF USING DISTILLER LIQUID AS A RAW MATERIAL FOR REAGENTS IN OIL PRODUCTION

One of the most high-tonnage products of inorganic chemistry is the production of sodium carbonate. Among the methods of its production, the Solvay method is of the greatest importance, it is based on the use of natural calcium carbonate and sodium chloride as raw materials. The availability of source resources and the simplicity of technological implementation ensure a high competitive attractiveness of the process. On the other hand, the volume of waste (up to 10 t of distiller liquid per 1 t of finished products) and the negative impact they have on the environment create significant problems in the operation of existing production facilities. The distiller liquid is an aqueous solution of calcium chloride and sodium chloride, which also contains gypsum and limestone. The paper considers the most important options for the use and processing of distiller liquid. Special attention is paid to electrochemical methods that make it possible to obtain products for oil production, in particular, acids and alkalis for the treatment of oil wells.
