Feed preparation, liquefaction & fermentation

The front end sets the conditions for downstream separation. Our cassava front end integrates storage, milling, liquefaction, saccharification and controlled fermentation.

01 / CNE

Connect the feedstock to the conversion route

Corn, cassava and wheat routes require preparation suited to starch conversion. Molasses and sugar-based feeds require a different front end. Feedstock composition, seasonal variation and handling conditions inform the process design; they also affect the solids and impurities presented to the downstream plant.

02 / CNE

Coordinate fermentation and distillation

The design aligns fermentation throughput and discharge conditions with the distillation feed requirement. Operating and laboratory information connects raw-material quality, conversion and fermentation performance to final product quality. Training covers the process route, equipment functions, routine observations and the records needed to investigate a deviation.

03 / CNE

Make the co-product route part of the design

Grain and cassava projects need a defined route for the non-ethanol fractions leaving the process. The mass balance identifies stillage, recovered solids, evaporation loads and water-reuse interfaces. These requirements should be resolved together with the production train rather than added after equipment selection.

Explore the engineering behind the project

Ubon Bio EthanolOur Ubon project has a capacity of 400,000 litres per day. CNE supplied the factory-manufactured process columns and shell-and-tube heat exchangers, with site fabrication and installation of fermentation and alcohol tanks and installation of process piping. The plant processes cassava and was subsequently upgraded for all-molasses operation.Start with your feedstockDifferent raw materials need different front ends.

Separation, evaporation and drying can be as important to the project as alcohol production.
