SYSTEM DESIGN FOR ETHANOL PRODUCTION FROM RECLAIMED PHOSPHATE LANDS

RECENT EXPERIMENTAL PROGRAMS HAVE SHOWN THE FEASIBILITY OF RECLAIMING FORMER PHOSPHATE MINING LANDS TO A LEVEL SUFFICIENT FOR COMMERCIAL ARICULTURE. THESE LANDS, LARGELY UNUSED AT PRESENT, ENJOY A CLIMATE CONDUCIVE TO LARGE-SCALE PRODUCTION OF POTENTIAL ENERGY CROPS, INCLUDING SWEET SORGHUM AND SUGAR CANE. SAVANT-VINCENT PROPOSES TO INVESTIGATE VARIOUS SYSTEM CONCEPTS FOR THE UTILIZATION OF SUCH BIOMASS RESOURCES IN THE PRODUCTION OF ETHANOL. IN ORDER TO IMPROVE THE ECONOMICS OF SUCH SYSTEMS, THE INVESTIGATION WILL EMPHASIZE THE COMPLETE UTILIZATION OF ALL PLANT COMPONENTS, INCLUDING CELLULOSE, HEMICLLULOSE, AND LIGNIN, AS WELL AS THE SUGARS. VARIOUS MEANS WILL BE SOUGHT FOR EXTENDING THE HARVEST AND PROCESS SEASONS IN ORDER TO MAXIMIZE THE UTILIZATION OF CAPITAL FACILITIES. SUPPLEMENTAL FEEDSTOCKS AND ATLERNATIVE BY-PRODUCTS WILL ALSO BE CONSIDERED IN ORDER TO MAXIMIZE OVERALL ECONOMIC YIELD AS A FUNCTION OF VARIABLE COMMODITY PRICES. THE OBJECTIVE OF THIS INVESTIGATION IS A PRELIMINARY SYSTEM DESIGN HAVING THE POTENTIAL TO PRODUCE ETHANOL AND OTHER BIOMASS DERIVATIVES AT COMPETITIVE PRICES. AS AN INTERMEDIATE GOAL, A COMPUTER-BASED ANALYTICAL MODEL WILL BE DEVELOPED TO ASSIST IN ANALYZING AND COMPARING ALTERNATIVE SYSTEM CONFIGURATIONS, CARRYING OUT VARIOUS OPTIMIZATION STUDIES, AND PROJECTING OVERALL ECONOMIC PERFORMANCE.
