Whole-Stillage Treatment and Combined Heat and Power for Cassava-Based Ethanol Production
This project adopts a cleaner production process. Drawing on our experience in the integrated treatment of wastewater (stillage) from cassava-based ethanol production, it uses two-stage anaerobic treatment of whole stillage. The anaerobic treatment system combines a mature, highly efficient thermophilic…

Heat Integration of Molasses-Based Ethanol Distillation and Stillage Concentration
Stillage from the distillation section is pre-concentrated using process waste heat, increasing its organic solids content from approximately 15% to approximately 30%. A live-steam-heated final concentration unit then raises the organic solids content from approximately 30% to 65–70%. The concentrate…

Ethyl Acetate Production by Ethanol Esterification
Ethyl acetate is produced by esterifying acetic acid with ethanol using sulfuric acid as the catalyst and a salt-based dehydration technology. The finished ethyl acetate meets GB/T 3728-2007, Ethyl Acetate for Industrial Use.

Glacial Acetic Acid Production from Ethanol
Glacial acetic acid is produced from fermentation-derived ethanol by two-stage oxidation: ethanol is first oxidized to acetaldehyde, which is then further oxidized to acetic acid. The finished acetic acid meets GB 1903-2008, Food Additive — Glacial Acetic Acid.

Acetaldehyde Production from Ethanol
Ethanol vapour is directly oxidized over a silver catalyst to produce dilute acetaldehyde, which is then concentrated by distillation to obtain the finished acetaldehyde product. Product specifications are: acetaldehyde ≥99.7% w/w; water ≤600 ppm; acidity ≤500 ppm.
