Real Gas Effects in Carbon Dioxide Cycles

Abstract: The potential performance of carbon dioxide as working fluid is recognized to be similar to that of steam, which justifies thorough thermodynamic analysis of possible cycles. The substantially better results achievable with CO2 with respect to other gases are due to the real gas behaviour in the vicinity of the Andrews curve. Simple cycles benefit from the reduced compression work, but their efficiency is compromised by significant losses caused by irreversible heat transfer. Their economy, howe… Show more

“…In this analysis the "condensing" cycle increases the efficiency to 48.3% for the same peak turbine inlet temperature. The condensing re-compression cycle was originally described in a series of reports by Angelino, (Angelino, 1967(Angelino, , 1968(Angelino, , and 1969, and it provided the foundation for the MIT research by Dostal (Dostal, 2004). In the condensing power cycle, the waste heat cooler condenses the CO 2 to a saturated liquid, at the compressor inlet, rather than a gas as in the Brayton cycle.…”

“…The first portion performed a series of power cycle analyses to assess the potential of S-CO 2 power systems to increase the efficiency by using a "condensing" recompression power cycle. This power cycle was first described by Angelino (1969) and later reviewed by Dostal (2004). The second effort consisted of performing a series of experimental tests using the Sandia S-CO 2 compression test-loop to validate the ability of these power systems to actually operate in the condensing mode.…”

“…A split-flow configuration, referred to as flow recompression in some references, is the baseline configuration for this work. The split-flow configuration, proposed by Angelino (1968Angelino ( , 1969, allows for an increase in efficiency of several percentage points as compared to a simple recuperated cycle. The reason for this is that the heat capacities for CO 2 are significantly different as a function of temperature and pressure.…”

“…In [11][12][13][14], the use of carbon dioxide for supercritical and condensation closed cycles is proposed. In the suggested cycles, the compression of the carbon dioxide occurs near the bubble line, close to the critical temperature (31.06 • C) and with the minimum pressure near the critical value (73.83 bar).…”
