| Abstract |
This report summarizes a conceptual plan of direct heat utilization of the geothermal resources on the Island of San Miguel, Azores, Portugal. This study was part of a larger project to assess the geothermal resources of the Agua de Pau massif in the center of San Miguel. The direct heat use plan proposed in a conceptual design is based upon the assumption that the waste brine from a single flash separation is available for high and low grade heat uses. The most appropriate uses of geothermal resource include refrigeration, salt production, milk and fruit dehydration, fish and fruit canning, sugar refining, prawn and fish farming, space heating for residential, educational and therapeutic facilities and tourist related activities. The economics impact of the direct heat uses is likely to be greater than that of the electrical power generation. The impact on primary service expansion is estimated at several hundred persons. |
