  • Publication number: 20120180512
    Abstract: A water recovery system for a cooling tower includes an intercooler having a first circuit portion and a second circuit portion. The first circuit portion is configured and disposed to receive a liquid desiccant and the second circuit portion is configured and disposed to receive coolant. A flash drum includes an inlet connected to the first circuit portion, a vapor outlet and a liquid desiccant outlet. A condenser is fluidly coupled to the vapor outlet of the flash drum. The condenser includes a condensate outlet. A cooling tower is fluidly connected to the liquid desiccant outlet of the flash drum and the condenser. The cooling tower includes a water stripper having a collector member, and a heat exchanger arranged below the water stripper. The collector member is configured to receive water laden liquid desiccant and the heat exchanger is configured and disposed to receive make-up water from the condenser.

  • Publication number: 20120159962
    Abstract: The present invention provides a water self-sufficient turbine system comprising: (a) a combustion turbine comprising a combustion chamber disposed between an upstream compressor coupled to a downstream turbine section; (b) a water recovery unit configured to contact a first liquid desiccant with a water-rich exhaust gas stream produced by the combustion turbine, and produce a water-enriched liquid desiccant and a water-depleted exhaust gas stream; and (c) a desiccant regenerator unit configured to contact the water-enriched liquid desiccant with hot compressed air to separate water from the water-enriched liquid desiccant to provide water-rich compressed air and to regenerate the first liquid desiccant; wherein the combustion turbine is configured to supply hot compressed air to the desiccant regenerator unit and receive water-rich compressed air from the desiccant regenerator unit, and wherein the desiccant regenerator unit is configured to supply the first liquid desiccant to the water recovery unit.

  • Publication number: 20120159924
    Abstract: A combined cycle power plant includes a gas turbine, a condensing stage, a steam turbine, and a heat recovery steam generator (HRSG). The HRSG is configured to generate steam for driving the steam turbine in response to heat transferred from exhaust gas received from the gas turbine at a first temperature and to transmit the exhaust gas to the condensing turbine at a second temperature that is lower than the first temperature.

  • Publication number: 20120031600
    Abstract: An intercooler includes a shell with an inlet and an outlet. The shell defines a first chamber. The intercooler further includes a plurality of elongate conducting members. Each of the conducting members includes a first end section and a second end section and is disposed such that each of the first end sections is inside the first chamber of the shell and such that each of the second end sections is disposed exteriorly of the shell. Each of the second end sections is disposed in a flow path of at least one cooling medium so as to undergo evaporative cooling.
