Revamp an idle distillery for a new feedstock

The Indonesia project moved from a cassava-based production history toward corn-based ENA and medical anhydrous ethanol. That change affects cleaning, milling, mash viscosity, enzyme duty, fermentation and the co-product route. The new fuel distillation/dehydration line was designed for switchable production with the existing line.

We first classify equipment for retention, repair or replacement. Inspection, materials, corrosion allowance, internals and available utility capacity determine what can be reused. Next, the engineering package fixes tie-ins, foundations, piping, controls and shutdown work.

Finally, define commissioning by system and product campaign. Keep host-plant capacity, individual package duty and alternative production modes separate. This makes the investment scope and the acceptance test understandable to both the plant team and the suppliers.
