Porokhnia M. The improvement of environmental safety of refined sodium bicarbonate production by minimization of gas and liquid wastes

The subject of the study is the processes of generation of refined sodium bicarbonate production wastes and minimization of their impact on dockillage. The subject of the investigation is the regularity of optimization of physical and chemical parameters of the process of carbonization of sodium bicarbonate solution and design features of bicarbonate columns for the production of refined sodium bicarbonate. The dissertation research is devoted to greening the production of refined sodium bicarbonate by optimizing the technological parameters of the carbonation process of a carbon dioxide solution and improving the design parameters of the main technological equipment of the process – bicarbonate columns. In the introduction, the scientific and technical relevance of the dissertation work is justified, the purpose and objectives are formulated, the object, subject and methods of research are defined, the connection of the work with scientific topics is shown, scientific novelty is given and the practical significance of the results obtained is formulated. The first section is devoted to a comprehensive analysis of scientific and technical information and information obtained at plants for the production of soda and soda products, on modern methods for improving the environmental safety of the production of refined sodium bicarbonate and the main technological parameters. The world experience in the production of refined sodium bicarbonate is considered and analyzed. Structural features of the main technological equipment – bicarbonate (carbonization) columns-are considered. The influence of refined sodium bicarbonate production on the state of the environmental in the areas of their location is revealed.
