Abstract
With the application of the Rankine-powered heat pump (RPHP), geothermal fluids at intermediate temperature (200-300°F) become a viable energy source. The RPHP converts low temperature heat to useable process steam and allows utilization of heat sources, which are too low to generate useful steam directly. Additionally the RPHP controls energy delivery temperature and rate, while producing superheated steam output. For geographic areas with abundant intermediate temperature resources, the RPHP is a flexible, economical means to generate process steam for industrial applications.
