OIL-FREE CRYSTAL GROWTH MODIFIERS FOR ALUMINA RECOVERY
摘要
Disclosed herein is a method of producing alumina trihydrate crystals from an alumina tnhydrate recovery process stream wherein an aqueous emulsion comprising an alkyl or alkenyl succinic anhydride is added to the alumina trihydrate recovery process stream, wherein the aqueous emulsion is substantially free of mineral oils. The method provides a decrease in percentage of alumina trihydrate crystals having a volume average diameter of less than about 45 micrometers compared to the percentage of alumina trihydrate crystals produced in the absence of the aqueous emulsion of an alkyl or alkenyl succinic anhydride.
