Economic Evaluation Report

for 40MGY Corn Oil Extraction (Back End)

1. EXECUTIVE SUMMARY (2007 prices)

Total Capital Investment $

Production Rate kg MP/yr

CoProduct Credits $ /yr

Capital Investment Charged to This Project $

Operating Cost $/yr

Steam Energy is reduced by 5.4% due to oil extraction (assuems drying energy is unchanged)

Ethanol Production Cost $ / Gallon

Notes:

Drying Energy (Nat. gas consumption) reduced by 26% - difference between baseline and 2022 Vanilla energy usage

Steam Energy usage is difference between 2022 Vanilla thermal energy usage and drying (Nat. gas) energy
