CCGT plant with full oxygenation

Cycle D5 is another variation of a CCGT plant with full oxygenation of the fuel as shown in Fig. 8.22 again it is a semi-closed cycle using pure oxygen. But now the CO2 is abstracted after compression, which may require the use of physical absorption plant. 

D4 the semi-closed CBT or CCGT plant with full oxidation—oxygen supplied to the combustion chamber instead of air, with CO2 removal at low pressure level ... 

CBT and CCGT plant. with full oxidation (D4. D5). We next consider two semi-closed cycles for CO2 removal (Cycles D4 and D5) with air replaced as the oxidant for the fuel, by pure oxygen supplied from an additional plant.
