Step by Step for Designing an Optimum Heat Exchanger Network
Webthe pinch point. Finally, the paper presents a detailed exampl e of heat exchanger calculation in two configurations: as a regenerative CO 2-CO 2 heat exchanger and as a CO 2 cooler with water on the cold side. The regenerative CO 2-CO 2 heat exchanger is currently considered inapplicable in CCS systems. However, it may be used for auxiliary ... WebIn this paper, a recompression S-CO2 Brayton cycle model that considers the finite-temperature difference heat transfer between the heat source and the working fluid, irreversible compression, expansion, and other irreversibility is established. First, the ecological function is analyzed. Then the mass flow rate, pressure ratio, diversion … WebThe combustion gases leaving the gas turbine flow thru a HRSG heat exchanger to heat the steam to 400 C at 10 MPa. The combustion gas leaves the HRSG at 420 K. The steam leaving the turbine is condensed at 15 kPa. ...
