Thread Content
What is the steam consumption in the ammonia-alkali process distillation? Everyone is welcome to participate! I’ll throw the brick first: ***Factory’s steam consumption per ton of alkali distilled: 1.35–1.45 tons.
The steam consumption for soda ash production in the ammonia-alkali process mainly comes from calcination and distillation, and this varies depending on the process. Generally, secondary steam can be generated during calcination for use in distillation. Additionally, it is necessary to consider whether other heat sources can be utilized to heat the mother liquor, thereby reducing the steam required for distillation.
Reply to 1# wal5980729: Does the steam consumption for distillation in your factory include the flash steam generated during calcination? If not, then your figure is the lowest in the country. We do not include steam used for calcination; we only take into account primary steam and compressed waste steam, and the total amount is less than 1.30 tons
