Dry steam power plants systems were the first type of
geothermal power generation plants built. They use the steam from the
geothermal reservoir as it comes from wells, then route it directly
through turbine/generator units to produce electricity. Flash steam
plants are the most common kind of geothermal power generation plants in
operation today. However, existing Dry Steam technology is not cost effective and it has low efficiency.
TransPacific superior heat recovery technology uses pressurized geothermal hot water that comes up from the reservoir through a production well. The water enters the ORC recovery boiler where TPE's refrigerant mixture vapor is produced. The vapor then spins the turbine, which in turn spins a generator that creates electricity. Low pressure vapor exiting the turbine condenses and is pumped back to the recovery boiler. The condenser can be air or water cooled. TransPacific's refrigerant mixtures are custom formulated for maximum heat recovery efficiency and optimum power generation at the low temperatures.
