Latest Patents

The provided information lists 1 patent for Guozhu Shi: “Method for Extracting Polyol from a Fermentation Process.” The method concentrates a polyol fermentation broth through evaporative dehydration, then rectifies and purifies 1,3-propanediol (PDO) to produce a steam condensate. Reverse osmosis separates that condensate into a concentrated solution and a permeate. The retentate returns to the evaporative dehydration stage, while the permeate can be reused as a fermentation ingredient, cleaning water, or in sewage treatment.

The patent specifies a water content of 5–25 wt% in the concentrated solution after evaporative dehydration and reports a PDO yield of 99.5%. The process is designed to support water recycling, reduce PDO and 2,3-butanediol (BDO) losses during concentration, and substantially decrease wastewater.

Career Highlights

Shi’s listed invention focuses on improving resource efficiency in polyol production. By combining evaporative dehydration with reverse osmosis and reuse of the permeate, the method integrates product recovery with water management.
