Abstract

The Hygroscopic Cycle is an innovative power cycle due to the significant energy and water consumption savings it allows. The cycle is currently in the improvement study phase. In this work, the refrigeration process of the cycle has been analyzed using dry-coolers and without the need to consume water, which confers a significant environmental and energy efficiency improvement of the process. The numerical study of the refrigeration of the Hygroscopic Cycle was carried out to improve its understanding and performance in order to obtain optimal results. A model of the equipment was first implemented using the Engineering Equation Solver software. Once modeled, the system was analyzed for different situations and working conditions and validated using the real data provided by the first power pilot plant that uses this cycle. That made it possible to design specific equipment that would respond to the needs of any installation that used the Hygroscopic Cycle.
