| Abstract: | The role of carbon dioxide as a green alternative solvent has garnered significant interest for its application in various industrial processes, including chemical reactions, separations, and material processing. Polyethylene glycol (PEG) is a valuable compound with extensive applications in industries such as pharmaceuticals, biotechnology, and chemical engineering. Precise estimation of viscosity of CO2-saturated PEG is crucial for several scientific and industrial applications, as viscosity directly impacts the material's performance and feasibility in specific processes. This study, hence, introduces machine learning models utilizing K-nearest neighbors, decision tree, adaptive boosting, multilayer perceptron artificial neural network, convolutional neural network, support vector machine, random forest and ensemble learning algorithms to accurately forecast the dynamic viscosity of CO2-saturated PEG based on PEG molar mass, pressure, and temperature. An experimental dataset is employed to facilitate the development of these intelligent models. Additionally, the leverage method is utilized to assess the authenticity of the data for model development, while a relevancy index is used to elucidate the relative contributions of each input factor to the viscosity. The findings suggest that all the collected experimental data are appropriate for inclusion in the construction of data-driven models. Moreover, it is revealed that pressure, temperature and PEG molar mass have a negative effect on the viscosity of CO2-saturated PEG. Ultimately, multilayer perceptron artificial neural network model is found to be the most accurate method for predicting CO2-saturated PEG viscosity. [ABSTRACT FROM AUTHOR] |
