Latest Patents

Among his latest patents, Slinkman has developed "Neopolyols suitable for crystal growth modification in the Bayer process." This invention provides methods and compositions for the addition of a crystal growth modifier (CGM) to precipitation liquor in the Bayer process. The CGM comprises a neopolyol, an ester derived from a neopolyol, and/or an ether derived from a neopolyol. Optionally, the CGM may include water, an antifoaming agent, and/or a hydrocarbon carrier liquid. This CGM is effective in significantly increasing the mean particle size of produced alumina crystals. Another notable patent is "Reducing aluminosilicate scale in the Bayer process." This invention offers a method to inhibit the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method involves adding specific silane-based small molecules to the liquor fluid circuit. These scale inhibitors effectively reduce DSP scale formation, thereby increasing fluid throughput and extending the operational time of Bayer process equipment. This innovation also reduces the need for costly and hazardous acid washes, leading to a significant reduction in the total cost of operating a Bayer process.
