Abstract
A method and arrangement for providing air to a gas turbine inlet, to facilitate energy production, are provided. In general, preferred methods involve both cooling air to be delivered to the gas turbine inlet, and also reducing the humidity content thereof. Preferred apparatus to accomplish the methods include: a water spray cooling arrangement; a liquid desiccant contactor; and, a vapor compression chiller arrangement. Preferably, cold solutions for operation of the water spray cooler and the liquid desiccant contactor are provided via absorption chiller arrangements.
Claims10
A method for providing relatively efficient operation of an air compressor arrangement;
- said method including the steps of:
- (a) providing an ambient air flow stream from ambient air having as temperature of at least 70.degree. F. and a relative humidity of at least 60%;
- and
- (b) conditioning the ambient air flow stream to provide an air flow stream to the air compressor arrangement at a first temperature of no greater than about 55.degree. F. and at a relative humidity such that the moisture content of the air in the air flow stream is no greater than an amount corresponding to saturation at a temperature of 5.degree. F. lower than the first temperature.
A method according to clam 2 including a step of:
- (a) conducting a second reduction of temperature by reducing the temperature of the separated gaseous phase from the step of reducing moisture content by spraying liquid desiccant, by a further step of directing the separated gaseous phase through a heat exchange coil arrangement of a downstream chiller arrangement;
- (i) said step of conducting a second reduction of temperature being conducted to form a gas stream therefrom having a temperature and relative humidity content such that the moisture content of the air in the air flow stream is no greater than an amount corresponding to saturation at a temperature of 5.degree. F. lower than the temperature of the gas stream from the second reduction of temperature.
