Information on the geothermal resources of the San Luis Valley, Colorado, has been gathered and reviewed and a preliminary, quantitative assessment of the magnitude and quality of resources present was carried out. Complete process designs were developed for the processes of producing crystal sugar from beets and for malting barley for use in the brewing industry, in each case adapting the processes to use a 302/sup 0/F geothermal water supply as the main process energy source. A parametric design analysis was performed for a major pipeline to be used to ship geothermal water, and thus deliver its heat, out of the San Luis Valley to three major Colorado cities along the eastern threshold of the Rocky Mountains. Cost estimates for capital equipment and energy utilization are presented. The analyses of the two process applications indicate favorable economics for conversion and operation as geothermally-heated plants. A major geothermal water pipeline for this region is seriously limited on achievement of the economy of scale by the physical absence of significant demand for heat energy. Finally, the development and utilization of Colorado's San Luis Valley geothermal groundwaters hold the potential to contribute to the prudent and beneficial management of that area's natural watermore » resources systems.« le
