Bio-Isobutanol Production from Corn - Cost Analysis - Isobutanol E11A

This report presents a cost analysis of bio-based Isobutanol production from corn using a typical fermentation process. In this process, distiller's dried grain with solubles (DDGS) and ethanol are generated as by-products.This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant.

This report presents a cost analysis of bio-based Isobutanol production from corn using a typical fermentation process. In this process, distiller's dried grain with solubles (DDGS) and ethanol are generated as by-products.This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses:* Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up* Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs* Raw materials consumption, products generation and labor requirements* Process block flow diagram and description of industrial site installations (production unit and infrastructure)This report was developed based essentially on the following reference(s):US Patent 8975049, issued to The Regents Of The University Of California in 2015Keywords: Butyl Alcohol, Biomass, Biofuel, Milling
