Applying Quality by Design to Digital Twin Supported Scale‐Up in Modular Plants

open access: yesChemie Ingenieur Technik, EarlyView.
Modular Plants are highly flexible and scalable and thus have potential utility to support faster time‐to‐process. Digital Twins of these modules require FAIR data and prior knowledge from the different domains in process development to describe the equipment capabilities. These equipment‐based Digital Twins can be combined with methods such as Quality

Corn cob pyrolysis: A systematic literature review of methods and applications

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Index Concepts for Differential-Algebraic Equations

open access: yes, 2015
We discuss several of different index concepts for differential-algebraic equation (differentiation, strangeness, tractability, geometric, perturbation, and structural index) and analyze their relationship.

Local sensitivity analysis of a supercritical extraction model

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from chamomile flowers. A parameter‐distributed model, consisting of a set of partial differential equations, was used to describe the governing mass transfer phenomena between solid and fluid phases under supercritical conditions using carbon dioxide as the solvent.

Estimating strongly wetting to non‐wetting contact angles for pure and mixed liquids on solids by considering film pressure

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract In solid–liquid–vapour systems, the effect of film pressure (πe$$ {\pi}_e $$) by vapour adsorbate molecules becomes significant when the solid surface energy is similar to or larger than that of the liquid. We extend Young equation applicability to estimate contact angles of pure and mixed liquids on smooth solids by including πe$$ {\pi}_e $$,
