Abstract
The report gives results of extensive testing of a prototype marble bed scrubber system for use in power plants. Results of 16 once-through soluble system tests, using sodium carbonate scrubbing solution, showed that the scrubber is a very good liquid/gas contacting device for SO2 removal from flue gases with an overall efficiency of 90 to 95 percent. Liquid/gas ratio and scrubber liquid composition significantly affected SO2 removal; other variables had little or no effect. Results of six limestone furnace injection system tests, using boiler calcined limestone and fly ash mixture, showed that solids concentration in the spray slurry and liquid/gas ratio signficantly affected SO2 removal. Results of six limestone tail-end system tests, using commercial limestone in a dual marble bed scrubber, showed that the SO2 removal efficiencies of the lower and upper beds are the same, based on the SO2 concentrations entering the respective beds. It was demonstrated that scale-free operation of both the furnace injection and the tail-end systems can be achieved in a closed loop system, without employing liquid blowdown, by maintaining 8 to 10 percent solids in the spray slurry.
