Title: Marie E Anderson: Innovator in Alumina Recovery Technologies
Introduction
Marie E Anderson is a notable inventor based in Trumbull, Connecticut, who has made significant contributions to the field of alumina recovery. With a total of two patents to her name, she has developed innovative methods that enhance the efficiency of alumina trihydrate crystal production.
Latest Patents
Anderson's latest patents focus on oil-free crystal growth modifiers for the Bayer process. The first patent discloses methods for producing alumina trihydrate crystals from an alumina trihydrate recovery process stream. This method involves adding an aqueous emulsion comprising a crystal growth modifier, which is either an acyclic anhydride or an alkyl or alkenyl succinic anhydride, to the recovery process stream. Notably, this emulsion is substantially free of mineral oils, leading to a decrease in the percentage of alumina trihydrate crystals with a volume average diameter of less than about 45 micrometers. The process eliminates the need for a defoamer or anti-foam agent to control foam generated during production.
The second patent also addresses the production of alumina trihydrate crystals using a similar method. It emphasizes the use of an aqueous emulsion containing an alkyl or alkenyl succinic anhydride, which is again free of mineral oils. This innovation results in a comparable decrease in the percentage of smaller alumina trihydrate crystals, enhancing the overall efficiency of the recovery process.
