Abstract
Systems which makes use of desiccant technologies have been widely studied because of its economic and environmental advantages. A well-known feature of this type of cycle is that it’s able to modify significantly the environmental conditions, performing an inlet air treatment by making use of pre-desiccant. Intercooling between compression stages is a common practice in gas power cycle design. The main objective is to reduce the required compression work between the ambient and turbine inlet pressures, thus unburdening the gas turbine and increasing the amount of available power. The intercooling effect is generally achieved by placing a heat exchanger between the compression stages, which rejects heat to the atmosphere and brings the air temperature back to the ambient level. The proposed system harvests this heat rejection to drive a desiccant cooling system. In turn, the cooling effect provided by the desiccant system is used to cool the air between the compression stages below the ambient level, allowing for a further reduction of the required compression work, when compared to standard intercooled cycles.
