Abstract

Combined cycle with closed brayton cycle, cold focus subambiental, with working fluids of high polytropic coefficient. Being the upper cycle a brayton cycle with a working fluid of high polytropic coefficient, the evolution of this fluid is the conventional one in the brayton cycle, increase of pressure and temperature in a compressor, heat acquisition of the hot focus, expansion in the turbine and transfer of heat to the cold focus, which will be the natural gas that is intended to regasify. As a lower cycle a rankine with water is used as a working fluid, its evolution is compression in a pump, heat acquisition of the hot focus (which is the brayton cold focus), expansion in a turbine and transfer of heat to the cold focus ( which will be the regasified natural gas). With the movement of the turbines, electrical energy is produced. All this process has a high specific work and performance. (Machine-translation by Google Translate, not legally binding)
