ZEP: a new process for abatement acid pollutants from waste gases

摘要

Incinerator fumes, after recovery heat boiler, must be to a temperature not lower than 150-160℃, so that the reaction of decomposition of sodium bicarbonate completely takes place. Powders of bag filter can be used to obtain an alkaline solution to be used in washing tower, so to decrease the production of solid waste materials. The solution to realize the alkaline washing tower in co-current followed by water washing in count-current, it can be applied since separator accommodated between two towers, minimizes liquid entrained. The realized pilot plant further on allows the possibility to test processes of abatement, also a flexibility of employment.
