摘要
A flue gas dry scrubbing process and system achieves higher sulfur dioxide removal efficiency with a better utilization of alkali reagent chemicals as well as increased dry product recovery performance using a combination of spray drying with an alkali reagent slurry and with a recycled stream comprising a mixture of unreacted alkali, sulfite and sulfate reaction products and flyash which directly contacts the sulfur dioxide-containing flue gas. Preferably the recycled mixture contacts the flue gas in the spray dryer (12). The invention utilizes a splitting method and a splitter apparatus (78) wherein the particle product powder is separated into two fractions for recycling (18) and for product disposal (82). The rate of splitting is fully adjustable over a wide range.
