I.G.P.C. Ethanol Plant

Aylmer, ON

Construction of the Aylmer Ethanol Plant is a design build facility using ICM technology set to produce 40 million US GPY of de-natured ethanol spanning a relatively short 16 month construction window. The plant is designed to process 40,300 bushels of corn per day requiring an annual supply of 14,230,000 bushels. The overall project is being constructed on 50 acres of vacant land and consists of several buildings and facilities comprising many processes; corn receiving, corn milling, cook water tanks, slurry tanks, liquefaction, enzymes, fermentation tanks, beer well tank, yeast propagation, CO2 scrubbers, evaporators, distillation, molecular sieves, whole stillage, centrifuges, process storage tanks, DDGS drying facility, fuel storage, ethanol load-out, DDGS conveying, water conditioning, thermal oxidation, cooling towers, waste water treatment, and chemical storage tanks.

Corn is delivered to the plant either by truck or rail to corn receiving, weighed and unloaded into dump pits. The corn is then transferred via conveyors into 3 large concrete silos. Corn milling draws from the silos and grinds the corn through hammer mills for supply to the process building again via conveyors. Dust collection equipment throughout the grain handling facility maintains proper dust control.

The process and energy center aspect of the plant consists of large volumes of equipment, specifically; 14 field erected and 46 shop fabricated stainless steel and carbon steel tanks, some 103 pumps, 18 heat exchangers, 11 agitators, and some 44 major equipment packages, plus roughly 43,000 feet of stainless steel and carbon steel piping, some 360 feet of large pipe racks, several pre-engineered buildings, as well as significant electrical distribution equipment and instrumentation.

As the final product ethanol is piped to carbon steel storage tanks within the tank farm for temporary storage. Ethanol load out equipment allows the final de-natured ethanol to be transported out of the facility again either by truck or rail. As an additional by-product the three centrifuges take the thin stillage and separate out wet cake which is sent to the two ICM dryers; the final DDGS product is sent to the DDGS building for temporary storage via pneumatic ductwork which is subsequently transported off site via truck or rail and sold as feedstock. The construction of this entire facility was completed in an astonishingly fast 16 month period, 1 month ahead of schedule.
