Abstract

This reseach introduces a novel Predictive Emission Monitoring System (PEMS) for Carbon Monoxide (CO) emissions in an auto-derivative gas turbine within a Floating
Production Storage and Offloading (FPSO) system. The PEMS utilizes a hybrid approach, integrating Artificial Neural Networks (ANN) with a Multi-Layer Perceptron (MLP) architecture and XGBoost for optimization. A thorough hyperparameter tuning process, using GridSearch, was performed to optimize both the ANN and XGBoost models. The ANN model was assessed with 20 parameter combinations, while the XGBoost model underwent fine tuning with an additional 20 combinations. The optimized model achieved a Root Mean Squared Error (RMSE) of 1.67, Mean Absolute Percentage Error (MAPE) of 1.88%, and an Rsquared (R²) of 0.94, highlighting its predictive accuracy. The research also examined the relationship between various engine parameters and CO emissions using visualization techniques like scatter plots, density plots, and box plots. Correlation heatmaps, SHAP(SHapley Additive exPlanations) values, and Permutation Feature Importance analysis identified N1 RPM (rotational speed) and compressor discharge pressure as the most influential parameters affecting CO emissions.
