Why is alkaline desulfurization technology commonly used for flue gas desulfurization in reactivation devices, rather than the ammonia-based desulfurization technique that is often used in boilers? What are the advantages and disadvantages of each of these two technologies?
The capital investment for alkaline methods is slightly lower than that for ammonia methods, and the desulfurization effect is better； The production of ammonium sulfate using the ammonia method can offset some of the operating costs; however, the operating costs are higher when the alkali method is used ；
