Abstract:

Regarding to the SOx and NOx contained in coke oven flue gas,an integrated wet desulfurization and denitration process and structure combining the processes of flue gas waste heat recovery,wet super turbulent ammonia desulfurization and forced oxidation of urea denitration is proposed.With application of this new technology,the discharged coke oven flue gas can meet the standard requirement after desulfurization and low temperature denitration,low pressure steam and ammonia sulfate are produced as by-products,escaping of ammonia can be avoided and no waste water or slag is discharged.
