• Abstract: We present data driven deep learning models for forecasting and monitoring amine emissions and key performance parameters in amine-based post-combustion carbon capture systems. Using operational data from the CESAR1 solvent campaign at Technology Center Mongstad, four DL architectures such as Basic Long Short-Term Memory (LSTM), Stacked LSTM, Bi-directional LSTM, and Convolutional LSTM were developed to capture time-dependent process behavior. For emission prediction, models were designed for 2-amino-2-methyl-1-propanol (AMP) and Piperazine emissions measured via FTIR and IMR-MS methods. System performance models target four critical parameters: CO$_2$ product flow, absorber outlet temperature, depleted flue gas outlet temperature, and RFCC stripper bottom temperature. These models achieved high predictive accuracy exceeding 99% and effectively tracked both steady trends and abrupt fluctuations. Additionally, we conducted causal impact analysis to evaluate how operational variables influence emissions and system performance. Eight input variables were systematically perturbed within $\pm$20% of nominal values to simulate deviations and assess their impact. This analysis revealed that adjusting specific operational parameters, such as lean solvent temperature and water wash conditions, can significantly reduce amine emissions and enhance system performance. This study highlights ML not only as a predictive tool but also as a decision support system for optimizing carbon capture operations under steady state and dynamic conditions. By enabling real time monitoring, scenario testing, and operational optimization, the developed ML framework offers a practical pathway for mitigating environmental impacts. This work represents a step toward intelligent, data-driven control strategies that enhance the efficiency, stability, and sustainability of carbon capture and storage technologies.
