How is the water demand calculated for desulfurization using the lime-gypsum method?

How is the amount of process water required per hour calculated? Thank you. . .

The lime-gypsum method typically involves internal circulation, with water being added as needed. The main sources of water loss are the moisture contained in the gypsum, the water that evaporates, and the water carried away by the flue gas from the desulfurization tower; the flue gas contains about 8% water. It is difficult to calculate the amount of water that evaporates, so an approximate value is usually given based on the specific conditions of the project. The moisture content in the gypsum, on the other hand, is easy to determine. Actually, there’s no need for complex calculations; if scaling occurs, simply add some water to maintain the pH level of the slurry

Isn’t water needed to mix the lime slurry?

Hello. Have you produced a thin, paste-like desulfurization slag using the lime-gypsum method? How to handle it
