This project aims to develop a novel technology of flue gas desulphurization for alumina industry. The successful completion of this project will provide a practical solution to the SOx emission problem in alumina refineries. Specifically, we aim to make use of the waste causticiser sludge discharged during the causticisation of the liquor streams and the used filter aid after the polishing filtration of the refinery pregnant liquors as reagent to remove SOx emitted by the power house and the alumina calciners. We also aim to recover some alumina during the process of flue gas desulphurization thus further reducing the cost of air pollution control.Read moreRead less
