Formula for calculating the cost of producing soda ash via the ammonia-soda process
Thread Content
Is there anyone who knows the cost calculation formula for producing soda ash via the ammonia-soda process? I would be extremely grateful! Thank you so much!
I seem to have heard of it, but never seen it. Can any friends help me out?

Then, calculate the consumption costs (costs of purchasing raw materials and various energy consumptions) + labor cost per ton of soda ash + equipment depreciation + equipment maintenance costs (the sum of these four items represents the manufacturing cost of soda ash). Finally, add the selling costs (including various taxes) to obtain the total cost of soda ash
It’s about calculating how much raw salt, how much synthetic ammonia, and how many kilowatt-hours of electricity are needed—giving specific figures. The calculations differ between the combined soda process and the ammonia-soda process. Do you know this? Please tell me about it
The typical consumption indicators for the ammonia-soda process are as follows: 1,420 kg of raw salt per ton of soda, 1,290 kg of limestone per ton of soda, 86 kg of bituminous coal per ton of soda, 3.0 kg of liquid ammonia per ton of soda, 1,250 kg of medium-pressure steam per ton of soda, 1,300 kg of low-pressure steam per ton of soda, 175 kWh of electricity per ton of soda, and 0.8 m³ of tap water per ton of soda. These figures for steam and electricity consumption assume that the turbine compressor is electrically driven rather than steam-driven; medium-pressure steam refers to the steam used in the calcination furnace, while low-pressure steam refers to the steam utilized in the sodium bicarbonate distillation tower. Hope this is helpful to you.
Thank you so much. If you need any help in the future, feel free to reach out to me. I work in the information field
It seems like the one upstairs is a bit too high....................:(
Master Lu... could you please tell us? That way, everyone can discuss it further
Based on the monthly output and raw materials consumed, the unit consumption of each raw material is calculated as follows: tons of coal per ton of soda ash + tons of ammonia per ton of soda ash + tons of salt per ton of soda ash + tons of stone per ton of soda ash + tons of anthracite per ton of soda ash + tons of water treatment chemicals per ton of soda ash + tons of sulfur per ton of soda ash + tons of magnesium chloride per ton of soda ash + tons of maintenance and repair costs per ton of soda ash + equipment depreciation + labor costs + self-incurred expenses related to packaging, storage, and transportation of finished products + external electricity costs per ton of soda ash + various taxes + allocated daily operating expenses = total cost per ton of soda ash
It’s so complicated. Are there any specific numerical ratios? For example, 1.2 tons of coal + 1.1 tons of ammonia
