I have a question regarding the consumption of sodium carbonate in refined salt

No one answered? Don’t everyone use refined salt?
What is the mass percentage of calcium in your refined salt? It is possible to calculate by adding the theoretical amount to the excess alkali amount to determine whether high consumption has occurred; here, the calcium content in the vacuum salt is around 0.018%
I calculated it and it’s within the normal range; however, my manager thinks it’s a bit high. I’d like to ask what the typical consumption is – why do some manufacturers claim it to be only 0.02 kg?
It should be related to the calcium content in refined salt, as well as to the control of excess alkalinity in the brine. It’s better to do a material balance and show it to the boss. Hehe.
The moderator upstairs is right; it depends on the calcium content in the refined salt and how well the excess alkalinity in the saltwater is controlled.
The amount of sodium carbonate used depends on the calcium ion content in the raw salt; its excess is generally kept between 0.25 and 0.5 grams per liter. Our facility consumes approximately 2.8 kilograms of it per ton of alkali produced.
The amount of sodium carbonate used depends on the calcium ion content in the raw salt; an excess amount is generally kept at 0.3 g/L. Let’s do some calculations first – I’m not sure what the specific consumption rate mentioned by the original poster refers to. In the several projects I’ve worked on, the amount of sodium carbonate (100%) used ranged from 0.85 to 2.2 kg per cubic meter of brine, and this amount is closely related to the mass of salt involved
We don’t use refined salt; instead, we use sea salt in amounts of 12–15 Kg
