Application of internal energy of aquifer fluid in geothermal plant

摘要

The present invention relates to a method of utilizing the internal energy of an aquifer fluid (a) containing geothermal water (T) mixed with gas (g) and a crude oil (E) in a closed circuit. It is an object of the present invention to obtain environmentally neutral, carbon dioxide free utilization of aquifer fluids and environmentally friendly supply of electrical and thermal energy.In order to achieve this, the beltwater fluid (a) is taken out from the aquifer (0) by the removing device (10), and the gas (g) is separated by deaerating the aquifer fluid (a) in the gas separator (11), and optionally the crude oil (E) is If necessary, the separation and thermal energy of hot water (T) are utilized in at least one system (12-14) to utilize thermal energy, and the extracted gas (g) and the arbitrarily separated crude oil are less WithAlso, combustion is performed in one combustion device (24, 24a), and the generator (25) is operated to utilize the internal energy of the gas (g) to separate CO2 from the exhaust gas and recycle it in the aquifer.Diagram
