24 Thermodynamic cycle analysis the TIT. However, the minimum TIT takes place at lower pressures in this configuration, which is why for a fixed pressure loss there is always a minimum TIT in Figure 2-19a. The trend of the regenerators load in Figure 2-19b is similar to that of the regenerative Brayton system. However, the values of the power are larger in this case since the vapor recompression system requires larger CO2 mass flow. 2-3-4 Operating conditions The same procedure followed for the first system configuration is used in this section to analyze a specific set of operating conditions for the Brayton recompression system. The minimum TIT and its correspondent discharge pressure are obtained for different pressure losses. The results are shown in Figure 2-20. 830 820 810 800 790 780 770 760 012345 ∆PLS [%] 310 300 290 280 270 260 250 012345 ∆PLS [%] (a) Minimum TIT. (b) Discharge pressure. Figure 2-20: Minimum turbine inlet temperature and its correspondent compressor discharge pressure for the Brayton recompression system as a function of the pressure loss (ηTR = 50%, T2 = 31.25◦C, P2 = 74 bar, ηHR = 90%, ∆TPN = 10◦C). The operating conditions used in this analysis correspond to a pressure loss of 2%, which gives a minimum TIT of 788◦C and a discharge pressure of 272 bar. The correspondent T-s diagram is shown in Figure 2-21. Apart from the lower TIT, the most important feature of this system is the value of the discharge pressure, which is almost half the value required by the regenerative Brayton configuration. The temperature profile of the regenerators is shown in Figure 2-22. One objective of the recompression system is to separate the low temperature stream in order to limit the real gas effects in the heat exchangers. Besides, both extremes of the low temperature regenerator are fixed to have a value as close possible to the pinch, which results in the almost parallel temperature profile presented in Figure 2-22a and improves the regeneration process. The temperature profile of the high temperature regenerator, shown in Figure 2-22b, shows the pinch located in the cold side of this heat exchanger, confirming the assumption made for the calculation of the mass flow fraction α in equation (2-18). Another feature of the vapor recompression system is the improved operation of the cooler. J.S.
