“…Some proposed exible operation strategies include variable CO 2 capture rates, bypass or venting systems, solvent storage [19,18,11], and time-varying solvent regeneration [12]. Although studies show that such exible operation strategies improve the economic viability of CO 2 capture [20,12,21,16], there is still a lack of research into the technical eects of process disturbances during exible operation. Thus, there is a justied need to develop practical experience in dynamic operation of CO 2 capture pilot plants, which can help improve the robustness of exible operation strategies [22].…”

“…To this end, many steady-state optimization studies such as equipment and solvent selection [6]- [9], system configuration [10]- [12], parameter settings [8] - [9] have been carried out, trying to improve the efficiency of the capture system. However, in the face of high energy consumption, more and more researchers realize that implementing flexible dynamic operation for CO2 capture is of great importance to make the technology be widely used in power engineering practice [4], [5], [13]- [20]. During the electricity peak load, the capture system should be able to reduce its capture rate rapidly to avoid the high cost of energy.…”

Solvent-based post-combustion CO2 capture plant has to be operated in a flexible manner because of its high energy consumption and the frequent load variation of upstream power plants. Such a flexible operation brings out two objectives for the control system: i) the system should be able to change the CO2 capture rate quickly and smoothly in a wide operating range; ii) the system should effectively remove the disturbances from power plant flue gas. To achieve these goals, this paper proposed a multi-model predictive control (MMPC) strategy for solvent-based post-combustion CO2 capture plant. Firstly, local models of the CO2 capture plant at different operating points are identified through subspace identification method. Nonlinearity analysis of the plant is then performed and according to the results, suitable local models are selected, on which the multi-model predictive controller is designed. To enhance the flue gas disturbance rejection property of the CO2 capture plant and attain a better adaption to the power plant load variation, the flue gas flow rate is considered in the local model identification as an additional measured disturbance, thus the predictive controller can calculate the optimal control input even in the case of flue gas flow rate variation. Simulation results on an MEA-based CO2 capture plant developed on gCCS show the effectiveness and advantages of the proposed MMPC controller over wide range capture rate variation and power plant flue gas variation.

“…Literature on modeling and simulation of carbon capture processes is vastly available which includes custom-based process models and flow sheet type simulation models. The objectives of this type of modeling and simulations include model validation against a pilot plant data or commercial plant, 130,131 parametric studies, 132,133 process design, 134 energy and economic analysis, 135,136 process modifications, 137,138 use of mixed solvents, 139,140 process integration, 141 flexible operation [142][143][144] and advanced strategies for online control and optimization. 145,146 The details of the above citations are not presented as carbon capture is not the main focus of this review.…”

Carbon dioxide (CO 2 ) emissions contribute considerably towards increasing greenhouse effect. Carbon capture and storage can reduce CO 2 emissions to a great extent but lacks economic feasibility. The economic feasibility of CO 2 capture could be boosted by utilizing the captured gas to produce valuable end products. CO 2 is a highly stable molecule; therefore, special catalysts and elevated conditions of temperature and pressure are required for its conversion. This review presents the current status of CO 2 utilization processes from various aspects, including thermodynamic, economic, and environmental impacts. The use of process systems engineering (PSE) tools and techniques in a broad spectrum, to improve the technical, economic, and environmental feasibility of these processes, is the major focus of this review. In this regard, a framework has also been presented showing the integration of various PSE techniques. All the related information in the form of tabulated data as well as qualitative and quantitative plots have been presented and critically analyzed.
