“…A thorough description of this can be found, for example, in the work of Wall et al (Wall et al, 2002). However, our approach is similar to that of Kang et al (Kang et al, 2011) and it is proposed that this model is sufficient to relate a power generation requirement to a flue gas flowrate and composition.…”

“…Normally the temperature of the reboiler is maintained between 110°C and 130°C at an operating pressure of 1.6-2.1 bar otherwise higher temperatures can result in thermal degradation of the solvent in the reboiler and the stripper. Steam can be extracted from the NGCC power plant from three different positions: clutched turbine, throttled turbine and floating crossover pressure [45]. The floating IP/LP crossover is the most feasible solutions for steam extraction [46].…”

h i g h l i g h t sSteady state simulation of natural gas combined cycle (NGCC) power plant. NGCC power plant with exhaust gas recirculation (EGR) to increase CO 2 concentration in flue gas. Steady state simulation of post-combustion carbon capture (PCC) process and CO 2 compression train. Advanced supersonic shock wave compressor used for the CO 2 compression. Heat integration of NGCC with EGR, PCC and CO 2 compressors to improve thermal efficiency. a b s t r a c tCarbon capture for fossil fuel power generation draws an increasing attention because of significant challenges of global climate change. This study aims to explore the integration of a 453 MW e natural gas combined cycle (NGCC) power plant with an MEA-based post-combustion carbon capture (PCC) process and CO 2 compression train. The steady state models of the NGCC power plant, the PCC process and compression train were developed using Aspen Plus Ò and were validated with the published data and experimental data. The interfaces between NGCC and PCC were discussed. Exhaust gas recirculation (EGR) was also investigated. With EGR, a great size reduction of the absorber and the stripper was achieved. An advanced supersonic shock wave compressor was adopted for the CO 2 compression and its heat integration was studied. The case study shows net efficiency based on low heating value (LHV) decreases from 58.74% to 49.76% when the NGCC power plant is integrated with the PCC process and compression. Addition of EGR improves the net efficiency to 49.93% and two compression heat integration options help to improve the net efficiency to 50.25% and 50.47% respectively. This study indicates NGCC including EGR integrated with PCC and supersonic shock wave compression with new heat integration opportunity would be the future direction of carbon capture deployment for NGCC power plant.

“…operating independently). The higher LCOE for the non-hybrid system is due to higher wind-power integration costs, higher resource adequacy costs, and increased costs of building transmission lines [29]. studied a wind-coal hybrid system for CCS equipped with amine storage and estimated a relative increase in profits of about 20% for optimized operation of the hybrid system when compared to heuristic based operation, under the assumption of perfect foresight.…”

a b s t r a c tThis paper explores a solution to problems associated with two promising technologies for decarbonizing the electricity generation system: high costs of energy penalty of carbon capture and storage, and the intermittency and non-dispatchability of wind power. It looks at the optimal design and operating strategy of a hybrid system consisting of a coal plant retrofitted with a post-combustion amine-based Carbon Capture & Storage (CCS) system equipped with the option to perform partial CO 2 capture, and a co-located wind farm. A linear optimization model determines the optimal component sizes for the hybrid system and capture rates while meeting constraints on annual average emission targets of CO 2 , and variability of the combined power output. Economic benefits result from capturing less CO 2 during high electricity price time periods and capturing more CO 2 during times of relatively low electricity prices or times when integrating wind power output would exceed the transmission capacity of the connector lines. The hybrid system has Levelized Cost of Electricity (LCOE) and Cost of Carbon Capture (CoC) comparable to those of a new Natural Gas Combined Cycle Power Plant (NGCC), and provides a mechanism for muting the variability of wind power in the same way an energy storage system would.
