Performance Indicator on OTEC Power System for Selected Working Fluids

Abstract

OTEC is a renewable energy the temperature difference between surface and deep seawater. A new ocean thermal energy conversion cycle with pre-heater, separator, internal heat exchanger and static mixer(OTEC-PSIM) is proposed and simulated using the HYSYS software package. Also, a performance criterion is proposed to help select the most optimal working fluid. Results indicated that a high mass heat of vaporization at the inlets of the evaporator and condeser corresponds to a high turbine and pump work and vice versa with, R717 being the most promising fluid among the selected working fluids except for its high toxicity.sing the HYSYS software package.
