The limestone-gypsum wet desulfurization system mainly involves the absorption section and the oxidation section. This includes mud drop movement, SO 2 absorption, limestone dissolution and sulfite/sulfate crystallization [90], [91], [92]. Fig. 5 shows the process flow chart of limestone wet desulfurization technology [93].The process was tested on a 200-cfm pilot plant on a coal-fired boiler. Various types of scrubbing equipment were evaluated. Up to 80 per cent sulfur dioxide removal was feasible. The consumption of limestone ranged between 20 and 30 per cent more than the stoichiometric requirements. Limestone is a naturally occurring calcium Flue Gas Scrubbing with Limestone Slurry Taylor
