Why is it important to include a steam jet ejector within the surface condenser in a binary-cycle geothermal power plant?

It is important to include a steam jet ejector within the surface condenser in a binary-cycle geothermal power plant to remove non-condensable gases (NCGs) that accumulate in the condenser. In a binary cycle plant, geothermal fluid heats a secondary working fluid, such as isobutane or pentane, which then vaporizes and drives a turbine. After passing through the turbine, the working fluid is condensed in the surface condenser. However, even in a closed-loop system like this, some amount of N....
