The soda ash manufacturing technology currently used in our country?
Thread Content
Having studied chemical engineering in the past, I’ve always been interested in processes. Today, I would like to discuss with you the currently employed soda ash manufacturing technologies in our country, as well as their advantages and disadvantages”
It seems that there are only a few methods, such as the combined soda ash-ammonia process, the ammonia-soda process, and the natural soda ash process. As for the Shin’asu method, I’ve heard of no domestic manufacturers using it.

Reply to 2# Bathe in the East: It is said that Henan Jinshan uses non-cryogenic carbonization technology, and its operation is quite stable! “Soda Ash Manufacturing Technology” provides a detailed introduction to this topic; I’m currently striving to learn it!

The natural soda process, the ammonia-soda process (invented in 1862 by the Belgian scientist Solvay), and the combined soda process (a soda production method successfully developed over three years from 1938 to 1940 by Chinese chemical expert Hou Debang; it was later named the “Hou’s Combined Soda Process”). These are the main methods. There were also other methods like the Leblanc process, but none of them found industrial application
