The existing steam generator at AI-Corn Clean Fuel didn’t have the capacity to produce enough steam required for the increased production rates. To accommodate the demand, a combined heat and power (CHP) generator was selected to produce electricity and steam.
Low carbon footprint production of motor fuel was crucial to the project, and required the installation of a 5.5 MW combustion turbine and HRSG with a supplemental fired duct burner. Once construction is complete, the next phase will begin, including on-site process engineering during check-out, commissioning, and plant start-up.
This $146M fuel alcohol plant expansion was completed ahead of schedule and under budget. It increased plant production from 50 million gallons per year, to 120 million gallons per year. A new combustion turbine will generate 5.5 MW of power and an additional 150,000 lb/hr of steam. These additions increased the plant-wide steam capacity from 80,000 lb/hr to 230,000 lb/hr.
