Soda ash process

China’s soda ash production technology is at the world’s leading level. Compared to Japan, one can only say that each has its own merits, given the differences in national conditions. Take the combined soda process as an example: there is virtually no market for ammonium chloride in Japan. Therefore, the Shin-Ashi method consumes hardly any ammonia and does not produce ammonium chloride as a by-product. China has a large fertilizer market, so our Hou’s process results in high ammonia consumption, but the ammonium chloride produced as a by-product also has high market value.
I completely agree. Currently, the ammonia consumption in the combined soda process is largely kept around 350, and the gap compared to the theoretical value is narrowing.
How about the ammonia-soda process? Please compare the domestic ammonia-alkali process and the combined-alkali process.
