What causes red alkali in soda ash?
Thread Content
Red alkali is produced in the ammonia-alkali method soda ash. What indicators should be controlled? Thank you :L
It is recommended that you read books on soda ash production such as "Soda Ash Engineering", "Ammonia-Alkali Process Soda Ash Technology", "Solvay Process Soda Production", etc., which have more detailed introductions.
Iron exceeds the standard, and the oxygen content of both gases exceeds the standard. Yesterday, I communicated with Sanyou. At present, their daily production is 5,700 tons. In addition, the monthly salary of technicians who go to Qinghai Wucai Mining is more than 10,000 tons. This salary is estimated to be the highest in the alkali industry currently.

The red alkali must be high in iron, corroded, and the passivation film is damaged.
I think back then, I only had more than 1k in Lianjia, and later it finally reached 2k. It’s really sad.
Nowadays, the income of eastern alkali plants is quite high.
Since everyone thinks that red alkali is caused by high iron, let’s raise another question. In our unit, the light gray iron was not high, and the heavy gray iron was not high, but the heavy gray was obviously red. Guess what is going on?
By the way, Wucai Mining now has 10,000+ technicians? I met them during the annual meeting this time, and I didn’t expect their income to be so high. . . . Not too low-key. . .
