Limestone desulfurization absorbent concentration issue
Thread Content
Flue gas desulfurization is carried out using the limestone-gypsum method, and Aspen is employed for simulation. Limestone slurry is difficult to simulate, so calcium hydroxide is used as a substitute. What should be the appropriate concentration of calcium hydroxide? Please ask the experts for guidance
It’s not easy to make such an estimate, as the spray slurry is a mixture of calcium sulfate, calcium sulfite, and calcium carbonate
