system of this invention generally 100 is shown to includes an additional heat exchanger he 7 i e the heat exchanger he 5 is split into two heat exchangers he 5 u2032 and he 7 designed to reduce the temperature difference between the stream having the parameters as at the point 10 and the streams having the parameters as at the points 8 and 29 in the new embodiment the stream with parameters as at the point 8 is sent into the heat exchanger he 7 where it is heated and further vaporized by a heat source stream such as a geothermal fluid stream having the parameters as at a point 44 producing the heat source stream having parameters as at the point 42 in a counter flow heat exchange process 44 42 and a stream having parameters as at a point 34 only then is the steam having the parameters as at the point 34 mixed with a recirculating stream having the parameters as at the point 29 as described above forming a combined stream having parameters as at the point 10 a temperature at of the stream having the parameters as at the point 34 is chosen in such a way that the temperature.
