【 摘 要 】

Merrick & Company has evaluated the economic potential for a Softwood Biomass to Ethanol Facility. A conceptual ethanol plant located in Martell California is economically attractive, particularly when co-located with an existing power generating facility. The plant, sized for an expected feed capacity of 800 dry tons per day converts the carbohydrates in forest product waste materials to ethanol and uses the lignin and residual carbohydrates to generate steam and electricity . This report documents the results of design and project evaluation work sponsored by the National Renewable Energy Laboratory (NREL) and performed by Merrick & Company, Architects and Engineers (Merrick), between March, 1998 and March, 1999. This project is a continuation of an effort begun in 1998 to study various aspects of ethanol related projects. Merrick has used NREL data and guidance to further develop cost estimates for the two stage dilute acid hydrolysis process for the production of ethanol from softwood. The Softwood to Ethanol Feasibility Study discussed in this report is an extension of previous, generic, softwood to ethanol studies. The co-located case is applied to a specific site owned by Wheelabrator near Martell, California. A large amount of potential feed material is available in the area and the site contains an existing solid waste fired boiler and power generating equipment. The evaluation of a specific site allowed better definition of a realistic installation and project. Staff consultations and site visits led to the selection of the portions of the Martell site for evaluation and the determination of which equipment was available and suitable. The work accomplished during this project includes: process designs, heat and material balances, process flow diagrams, equipment selection, capital and operating cost estimates, and market assessments for the ethanol product. The specific co-located plant at Martell was evaluated to identify specific modifications required to the equipment to fit the existing plant requirements.
