Abstract: Making caustic soda by ionic membrane is the rise of new technologies in chloralkali industry. This paper introduces the characteristics of ionic membrane caustic soda, and by pared existing production method, determines the advantages in the development space of ionic membrane caustic soda. This paper will system introduced the production technology of ionic membrane caustic soda, and the salt water refining, electrolysis, evaporation ,flake caustic section has made the process flow design and choice. On the base of one hundred thousand tons per year production requirements, the calculation of material
