Abstract The ammonium sulfate‐soda method is a procedure that produces soda ash and the by‐product ammonium sulfate, using mirabilite as the raw material. Here, a process for producing soda ash by the ammonium sulfate‐soda method is proposed. Based on the reaction mechanisms occurring in the Na 2 SO 4 ‐NH 3 ‐CO 2 ‐H 2 O system and the kinetic‐thermodynamic data of the CO 2 absorption process using aqueous NH 3 , the soda ash production process is modeled and simulated using Aspen Plus. The effects of ...
