Energy efficient design of membrane processes by use of entropy production minimization
Magnanelli, Elisa; Wilhelmsen, Øivind; Johannessen, Eivind; Kjelstrup, Signe (Journal article; Peer reviewed, 2018)To minimize entropy production means to reduce the lost work in a process, and to optimize the use of energy resources. Due to the need for re-compression, membrane units for separation of CO2 from natural gas require large ... -
Entropy Production Minimization as Design Principle for Membrane Systems: Comparing Equipartition Results to Numerical Optima
Magnanelli, Elisa; Johannessen, Eivind; Kjelstrup, Signe (Journal article; Peer reviewed, 2017)Entropy production minimization procedures presented in literature show that under different assumptions the optimal solution might be characterized by different thermodynamic quantities being constant. These constant ... -
Understanding and Reducing the Entropy Production in Membrane Systems From Gas Separation to Natural Systems
Magnanelli, Elisa (Doctoral theses at NTNU, 2017:97;, Doctoral thesis, 2017)The purpose of this thesis was to understand how energy is dissipated in various systems, in order to find general rules that can help increasing the energy efficiency of such systems.We mainly focused on membranes for ...
