LOW TEMPERATURE GEOTHERMAL SYSTEM

摘要

A new thermodynamic cycle is disclosed for converting energy from a low temperature stream from an external source into useable energy using a working fluid comprising of a mixture of a low boiling component and a high boiling component. The cycle is designed to improve the efficiency of the energy extraction process by mixing into an intermediate liquid stream an enriched liquid stream from which the energy from the external source stream is extracted in a vaporization step and converted to energy in an expansion step. The new thermodynamic process and the system for accomplishing it are especially well-suited for streams from low-temperature geothermal sources.
