A Surrogate-Assisted Approach for the Optimal Synthesis of Refinery Hydrogen Networks

Abstract: This paper presents a surrogate-assisted methodology for the optimal synthesis of refinery hydrogen networks, which fully considers the impact of vapor−liquid equilibrium in the flash separation unit, to study the interactions between the varying K-values and the optimal configuration of the overall hydrogen network. In addition, the formations of light hydrocarbons and hydrogen sulfide in the hydroprocessing reactors are calculated by the proposed method. To deliver a more accurate and efficient modeling and … Show more

“…Surrogate models are data-driven techniques, which are used to build empirical relations describing the mapping between input and response variable(s). 44,54 Although this definition can involve a very wide range of data-based models, including the simplest types (e.g., linear or polynomial regressions), the term is usually associated to nonlinear multivariate models like ANNs, GPs, OK, support vector regression (SVR), etc. 55 Surrogate models can be trained using real data collected by sensors from the physical systems or using simulation data generated from a complex FPM for the purpose of its simplification.…”
