Is soda ash a downstream product of coal chemical industry? How is soda ash produced? Thank you teachers. I am a novice.
There is a lot of information like this in the forum. Could you please search for it?
Reply 2# chen-jun-1024 I saw it but didn’t understand it. I don’t know what’s going on.
Soda ash itself is not. However, if the carbon dioxide used to produce soda ash is produced through coal gasification, transformation, methanol washing and other processes, then soda ash can also be regarded as a coal chemical product. There is also soda ash produced by the ammonium-alkali method, whose carbon dioxide is obtained by calcining limestone, so it cannot be counted.

Soda ash can be produced through coal chemical industry, so it can also be called coal chemical industry. The principle is as follows: NH3+H20+CO2=NH4HCO3 NH4HCO3+NaCl=NH4Cl+NaHCO3, separate NH4Cl and NaHCO3 and calcine NaHCO3 to obtain soda ash and release CO2
That depends on how you divide it. Natural gas can be used as the initial raw material for soda ash, and coal can also be used as the initial raw material for soda ash, so soda ash should also be regarded as a coal chemical product.
What we call coal chemical industry generally refers to the ammonia synthesis process using coal as raw material, including methanol, urea, etc. The soda ash industry belongs to the category of inorganic chemicals and is a very mature industry.
