Research Progress of wet FGD process with waste marble

摘要

Marble powder is produced during the production of marble waste, the Chemical compositions of marble wastes were comparable with limestones. Therefore, the marble powder can be used instead of limestone flue gas desulfurization. In view of these, the marble powder can be alternative sorbent in WFGD. This paper reviews the research of the wet flue gas desulfurization of marble powder in lieu of limestone, including the advantages of marble powder and the benefits of using marble powder for environmental protection. At last, the problems and future prospects of flue gas desulfurization in the actual production process using marble powder are discussed.
