  • Patent number: 5426941
    Abstract: A vapor condensation and liquid recovery system is provided where a turbine chamber is connected to a multi-chambered condensation unit. Each chamber of the condensation unit has a valved inlet port and a valved outlet port. The valved inlet ports of each chamber of the condensation unit are connected to the turbine chamber outlet. Each condensation chamber is provided with another valved port which is connected to a vacuum generating means. Each chamber is also provided with a further valved port connected to a purge pump. The valved outlet ports are connected to a fluid reservoir. All of the valves are opened and closed by valve control means such as a computer. The valve control means opens and closes the valved vacuum line, valved inlet ports, valved outlet ports, and valved purge line in a sequence to permit a condensable vapor to be continuously drawn through the turbine chamber where it rotates the turbine blades transferring energy from the vapor to the turbine shaft. As a result the vapor condenses.
