Title: Chosei Sato: Inventor in Alumina Processing
Introduction
Chosei Sato is an inventor associated with Yokohama, Japan, and Showa Denko Kabushiki Kaisha. His work includes an invention addressing heat recovery and sand removal during alumina production using the Bayer process.
Latest Patents
The available information lists one patent for Sato: “Device for Waste Heat Recovery and Sand Removal in the Bayer Process.” The invention brings overflow from a multistage red mud thickener into counterflow contact with steam produced by flashing bauxite-dissolved slurry, enabling heat exchange. It also removes sand by regulating the slurry discharge rate at the bottom of a column and recirculates the heated overflow for use as wash water in an earlier thickener stage. The method performs these operations in a single column, with a device incorporating pipes for overflow and slurry, an overflow-type condenser, and a sand-removal pipe. Sato’s listed patent portfolio comprises 1 patent.
Career Highlights
Sato’s documented patent work focuses on integrating heat recovery, slurry treatment, and sand separation into a single-column process. This approach connects energy reuse with material handling in Bayer-process alumina manufacture.
Collaborations
Sato’s listed coworkers include Yasutoku Yamada and Yoshiyuki Takenaka. The available information identifies Showa Denko Kabushiki Kaisha as his company.
Conclusion
Chosei Sato’s recorded invention combines heat exchange, sand removal, and overflow reuse in one column to support alumina production through the Bayer process.
