Post-combustion capture has the potential to mitigate climate change through the reduction of CO2 emissions in the short term. Chemical absorption-based processes are the most mature technology, but process costs should be reduced to facilitate their worldwide application. In this context, we address the optimal design of absorption-based carbon capture technologies using the Aspen Plus platform in the equation-oriented (EO) mode. We show the efficiency of this tool by solving optimal design problems for three case studies: (i) conventional process using monoethanolamine; (ii) conventional process using 2-methylpiperazine; and (iii) advanced flash stripping (AFS) configuration using piperazine (PZ). The objective function is the carbon dioxide avoided cost, and we consider a flue gas with a CO2 concentration of 7.5% (molar basis). Numerical results indicate that the AFS configuration with PZ has the best energy efficiency (2.46 GJ/t-CO2) and achieves the lowest CO2 avoided cost, with a value of 98.8 $/tonne-CO2.

Carbon utilization in natural gas combined cycle (NGCC) power plants has attracted great attention due to necessary carbon reduction demands. In this study, NGCC power plants integrated with the carbon capture and utilization process (CCU) were developed: Case 2 (NGCC power plant with CO 2 conversion on precarbon capture) and case 3 (NGCC power plant with CO 2 conversion on postcarbon capture). Integrated process configurations were evaluated and compared with case 1 (NGCC power plant only with postcombustion carbon capture) in terms of technical (net power generation, natural gas consumption rate, syngas production rate, CO 2 quantity released into the environment) and economic (total capital cost, total annual revenue, return on investment, payback period, and cash flow) performance. Here, case 2 represented the most environmentally friendly option with the lowest CO 2 released. Besides, case 3 generated the highest amount of electricity due to a lower compression pressure demand for CO 2 utilization than storage in case 1. The economic analysis indicated that the payback periods of cases 1, 2, and 3 were 9.2, 17.18, and 6.9, respectively. Case 3 was the best option under the least capital expenditure, operating expenditure, and the highest annual revenue. Additionally, case 2 was competitive in terms of low total capital cost as compared to case 1. Therefore, the suggested NGCC power plant processes with CCU are viable options for reducing CO 2 emissions and improving the economics of NGCC power plants. In addition, the process may be used as a model for further CO 2 utilization from flue gas released by gas power plants.
