摘要：Concerns over greenhouse gas emissions are driving a requirement for newly built coal power units to satisfythe so-called “capture ready” conditions. This paper presents the a thermo-economic analysis supplemented bya cost evaluation of a power unit for ultra-supercritical parameters expanded by an amine-based CO2 captureplant. The analysis was performed with the use of an integrated package containing the IPSEpro, MATLAB andRevenue Requirement Method implemented in MOExcel. The 0D model of a post combustion capture installationwas developed based on complex CFD calculations of the absorber and stripper. A number of CFD simulationswere conducted to create a large database, which was then utilized to develop suitable correlations describing theprocessThermodynamic and economic calculations were performed in respect of a power plant coupled with a CO2separation unit for a varying ratio of amine solvent to the exhaust gas stream (L/G). A local minimum for reboilerheat duty was found for L/G3.5 revealing the optimal post combustion capture configuration. It was observed thatcomplementing the power unit with a post-combustion capture (PCC) installation causes a slight increase in theinvestment costs due to the drop in efficiency, but more important is the rise in total cost due to the investmentassociated with the CO2 capture plant. It was found that about 14 years is required to compensate the investmentcost of the PCC installation.
