Abstract

Ciclo combinado con ciclo Brayton cerrado, foco frío subambiental, con fluidos de trabajo de elevado coeficiente politrópico.#Siendo el ciclo superior un ciclo Brayton con un fluido de trabajo de elevado coeficiente politrópico, la evolución de este fluido es la convencional en el ciclo Brayton, aumento de presión y temperatura en un compresor, adquisición de calor del foco caliente, expansión en la turbina y cesión de calor al foco frío, que será el gas natural que se pretende regasificar. Como ciclo inferior se utiliza un Rankine con agua como fluido de trabajo, su evolución es compresión en una bomba, adquisición de calor del foco caliente (que es el foco frío del Brayton), expansión en una turbina y cesión de calor al foco frío (que será el gas natural ya regasificado). Con el movimiento de las turbinas se produce energía eléctrica. Todo este proceso tiene un elevado trabajo específico y rendimiento.Combined cycle with closed Brayton cycle, subambiental cold focus, with high polytropic coefficient work fluids. # The upper cycle being a Brayton cycle with a high polytropic coefficient work fluid, the evolution of this fluid is the conventional one in the Brayton cycle , increase in pressure and temperature in a compressor, heat acquisition from the hot spot, expansion in the turbine and heat transfer to the cold spot, which will be the natural gas that is intended to be regasified. As a lower cycle, a Rankine with water is used as a working fluid, its evolution is compression in a pump, heat acquisition from the hot focus (which is the cold focus of Brayton), expansion in a turbine and heat transfer to the cold focus ( which will be the natural gas already regasified). With the movement of the turbines, electrical energy is produced. This whole process has high specific work and performance.
