Abstract: In this study, we proposed a new artificial neural network (ANN) trained with particle swarm optimisation (PSO) to predict solubility of CO₂ in aqueous amine-based solvents over wide range of pressure, temperature, overall concentration, and MWa. The model was developed with mixtures that consisted of methyldiethanolamine (MDEA), monoethanolamine (MEA), diethanolamine (DEA), 2-amino-2-methyl-1-propanol (AMP), diisopropanolamine (DIPA), piperazine (PZ), triethanolamine (TEA), and tetramethylen sulfone (TMS). PSO is used to find best initial weights and biases of neural network. As input parameters, neural network considered the overall solute's concentration, temperature, CO₂ pressure, and MWa. The PSO-ANN model was trained, and tested using 75%, and 25% of all experimental data points, respectively. The results show that the proposed model provides predictions in acceptable agreement with experimental data.
