Upgrading of a corn-ethanol facility

Varennes, Quebec, Canada

Description

GreenField is the leading specialty ethanol producer in Canada, with an export business in grain neutral spirits. The Greenfield Ethanol Varennes plant, a model for water and energy efficiency, is the first ethanol plant to be built in Quebec.

In 2008, Greenfield Ethanol decided to undergo a site wide expansion in order to achieve additional throughputs to reach up to 175 MMLPY. Genesys played a major role in the plant upgrade offering a major support and expertise, which involved the upgrading of the vacuum distillation section, modifications to the existing plate & frame exchangers, the addition of a new centrifuge and a new cooling tower and the upgrading and replacement of various pumps. It was also suggested that a fourth fermenting tank must be installed in order to reach higher targets in the years to come.
