Use of geothermal heat for sugar refining. Final report, October 1, 1976--May 31, 1977
The economic and technical feasibility of applying low grade geothermal heat (less than 300/sup 0/F) in the beet sugar refining industry for both new factory construction and retrofit conversion of existing factories was assessed. The representative Holly Sugar factory at Brawley, California, was utilized as a baseline primarily because of its centralized location with respect to the known and partially developed geothermal anomalies at Brawley, East Mesa, and Heber. Nominal values for the key parameters of the sugar refining process and typical values for the geothermal fluid parameters representative of geothermal resources in areas of existing or potential future sugar factories were defined, promising points of application were identified, and conceptual designs synthesized for introducing the geothermal heat into the process. The design approaches were then quantified with capital, operating and maintenance costs, and comparative economic evaluations were made with other fuels projected to 1995. In parallel with the detailed study of process conversion to geothermal heat, the existing pattern and potential growth of the sugar refining industry was assessed to estimate the potential market for new factory construction at suitable areas, as well as the potential for retrofit conversion of existing factories. The environmental impact of other geothermal application concepts was also assessed, and expected technological or industry/government policy changes which might affect the potential for conversion to geothermal heat were identified and evaluated. Emphasis was placed on achieving results that would stimulate commercial utilization of geothermal heat for beet sugar refining and related processes.
