In the steam cycle, thermal energy is needed to heat circulating water. In general, this energy is provided by eight-stage steam extraction for a standalone CFPP. Once CFPP is integrated with CO2 capture and DAPTinhibitor process, energy saving could be achieved by coupling the hot streams of capture and compression process with the steam cycle to heat circulating water. The properties of hot streams are presented in Table 7. The stream named ‘CO2 cooling’ is from the last compressor and required to be condensed to enter a pump. It should be noted that the heat load of the stream shown here does not involve the heat of condensation because the condensation temperature is too low to be utilized. The highest temperature of hot streams in Table 7 is 167 °C whilst circulating water is heated from 34 °C to 175.9 °C in LP condensate heaters and then is heated from 175.9 °C to 272 °C in HP feedwater heaters. Therefore, only circulating water in the low-temperature section can be heated by waste heat from CO2 capture and compression process.
