ABSTRACT
The quasi-combined cycle on CO2, calculated in Chapter 3, was supplied with oxygen from an external source, not integrated within the unit schematic. The bottoming air cycle here is absent. In this chapter, more rigorous calculations should be undertaken as the subject, the ZEITMOP cycle, contains an ion transport membrane (ITM) oxygen reactor and bottom cycle. The working substance here is not pure CO2 but a mixture with a percentage of steam before entering the turbine, which affects the thermodynamic properties. As these conditions produce rather high temperatures, the working substance is considered a mixture of ideal gases. The process in the compressor, however, is complicated and all the thermodynamic equations of Section 3.1 should be taken into account.
