In the production of sodium bicarbonate, the mother liquor after separation and dehydration is used for hot alkali circulation to dissolve and recover alkali powder in furnace gas, which constitutes the production process cycle. During The cyclic dissolution process, part of the alkali solution is sent to the ammonia distillation tower, and ammonia in the hot alkali solution is distilled out to further concentrate the alkali solution, the ammonia, carbon dioxide and water mixture from the top of the ammonia column is distilled as a raw material for the production of sodium bicarbonate and enters the original furnace gas cooling tower. The furnace gas is recovered with hot alkali, so that the alkali powder is dissolved in the alkali solution.
waste alkali solution recovery method: in the process of soda ash production, the furnace gas produced by the soda ash calciner still contains more alkali powder after cyclone separation.gas-solid phase method: Sodium carbonate is placed on the reaction bed (reaction tank), and mixed with water, carbon dioxide is blown into the lower part, and after primary reaction and carbonization, the primary crushing is carried out for secondary carbonization reaction, after drying and grinding, the sodium bicarbonate product was prepared.When Be, the reaction is finished Sodium bicarbonate is obtained by cooling, crystallizing, filtering to obtain sodium bicarbonate crystals, and then air-drying to obtain the final product. 25MPa, to be the material concentration of 13. Be The concentration of carbon dioxide in the lime kiln is maintained at 20% ~ 25%, after washing and purification treatment, and the hot alkali solution is carbonized, and the Tower pressure is maintained at 0. gas-liquid phase method: After dissolving and filtering the soda ash to remove impurities, the concentration was maintained at 23 to 24.Sodium Hydrogen Carbonate - Risk and Safety The addition amount in wheat flour was 20G./kg. Often with ammonium bicarbonate formulation leavening agent for biscuits, cakes.
At the same time, it is also used as a detergent for wool, foam extinguishing agent, bath agent, etc. It can also be used for film production, tanning, mineral processing, smelting, metal heat treatment, fiber, rubber and agricultural seed soaking. Can be directly used as raw materials in the pharmaceutical industry.
#Sodium hydrogen carbonate formula generator#
It is used as a starter in the food industry, a generator of carbon dioxide in soft and cold drinks, and a preservative for butter. Used as analytical reagents, also used in inorganic synthesis and pharmaceutical industry Used in food, medicine, film production, tanning, mineral processing, metallurgy, fiber, rubber and other industries, can also be used as detergents, extinguishing agents, used as food industry starter, soda and cold drinks in the generation of carbon dioxide Solubility H2O: 1 M at 20☌, clear, colorless
Properties white powder or opaque monoclinic fine crystals.
