The influence of interfacial transfer and film coupling in the modeling of distillation columns to separate nitrogen and oxygen mixtures
Kingston, Diego; Wilhelmsen, Øivind; Kjelstrup, Signe (Peer reviewed; Journal article, 2020)Coupling between heat and mass transfer occurs across interfaces and in vapor and liquid films. In this work, we present the first rigorous investigation of the role of these physical phenomena in the mathematical modeling ... -
Minimum entropy production in a distillation column for air separation described by a continuous non-equilibrium model
Kingston, Diego; Wilhelmsen, Øivind; Kjelstrup, Signe (Journal article; Peer reviewed, 2020)In this work, we apply the rate-based model of Taylor and Krishna to describe the separation of air in a low-pressure, packed distillation column. By use of numerical optimization, we identify the temperature profile for ...
