Thermal plant of a brayton cycle and a series rankine cycle for liquefied natural gas regasification facilities

摘要

Thermal plant of a Brayton cycle and a Rankine cycle in series, for installations of liquefied natural gas, which allows the use of the cold generated by the regasification process of liquefied natural gas to increase thermal efficiency, by associating a closed Brayton cycle Regenerative and a regenerative Rankine steam cycle, where the combustion gases first give heat to the Brayton cycle and then give heat to the Rankine cycle. The Brayton cycle can operate with nitrogen, helium or dry air. Cooling of the working fluid of the Brayton cycle at the compressor inlet is carried out by the liquefied natural gas when it is regasified. # The heat rejected by the combustion system after having ceded all possible heat to the Brayton and Rankine cycles, It is used to heat combustion air.
