Solvay soda ash ammonia process remains one of the main methods for obtaining sodium carbonate, despite its considerable natural resources. This process consists of consecutive stages: absorption, carbonation, distillation and calcination. And performance of each stage is determined to considerable degree by performance of other stages. As in any chemical process thermal and barometric modes, besides concentration of initial material flows, significantly influence processes efficiency. Ammoniated brine carbonation is the main stage in soda ash process. In this article, basing on analysis of numerous data on existing carbonation systems performance, we considered peculiarities and basic ways for increase of these systems efficiency that influence plant operation in general.
