This paper investigates multiple methods of machine learning for an application of surrogate modeling and optimization of an experimentally validated pressure swing adsorption model, evaluating their accuracy and precision compared to the more widely used method of artificial neural networks. In addition, some means of improving the machine learning model's accuracy with at-hand process knowledge and parameters were explored, which was followed by the optimization of the purity and recovery parameters of the system, finishing with a quantification of the total computational time employed. All steps described were developed and finished successfully using the open-source Python programming language, and the expected and unexpected results were discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
