the mechanism of the carbonization stage in the production of soda ash by the ammonia method is given. A mathematical model was constructed based on the overall kinetic reaction of the carbonization stage, and the temperature dependence of the content of bound NH4Cl in the suspension was considered. Mathematical models of the effect of carbon dioxide supply on the size of the absorption and refrigeration zones are presented. Calculation and graphs of the presented mathematical models are made. A practical calculation of the material and heat balance of the absorption stage was made.

Keywords:mathematical models, soda ash, carbonization stage, the absorption stage.
