Steam consumption for light soda ash in various soda ash plants.
Thread Content
We use the ammonia-soda process. The steam used in the calciner is superheated steam at around 3.0 MPa and a temperature of 275 degrees Celsius. The moisture content in the sodium bicarbonate is approximately 15%. Our consumption of medium-pressure steam is about 1,300 kg. I wonder what the consumption rate is at other companies. Feel free to post your replies.
But our furnaces are too old; two of them are over 50 years old. Moreover, they are all 2.5m furnaces with low capacity and high losses.
They’re pretty much the same. We use steam at 3.2 MPa; the steam consumption is generally less than 1.3
