Seeking information on the raw material consumption in the ammonia-soda process for producing soda ash
Thread Content
Who knows what the raw material consumption is for producing soda ash using the ammonia-alkali process?
It’s not clear; it varies from factory to factory
To produce one ton of soda ash, 1.5 tons of raw salt, 3 tons of steam, and 100 kWh of electricity are required
It’s about the consumption quotas for raw materials. I’ve been working on this topic recently, and I thought it would be good to share it with you for discussion. From what I understand, the requirements are as follows: 1.55 tons of raw salt, 1.3 tons of limestone, 0.135 tons of coke, 4.5 kilograms of liquid ammonia, 320 standard cubic meters of carbon dioxide, 15 cubic meters of tap water, 85 kWh of electricity, and 4.5 tons of steam
Soda ash consumption in the ammonia-alkali process: Raw salt: 1550 kg (desalinated salt); Limestone: 1250 kg; Coke: 100 kg (84% purity); Liquid ammonia: 3.5 kg; Fresh water: 3 cubic meters; Electricity: 90 kW/h; Steam; Light alkali: 2700 kg, with an additional 450 kg of heavy alkali; Recycled water: 90 cubic meters

The above is the ammonia-alkali process! Sodium hydroxide: 340-350 Kg; Ammonia: 215-230 kWh; Steam: 1.4-1.6 tons; Salt: 1.15-1.2 tons
