Analysis of a fluidized bed membrane reactor for butane partial oxidation to maleic anhydride: 2D modelling

Hydrogen production in a Pore-Plated Pd-membrane reactor: Experimental analysis and model validation for the Water Gas Shift reaction

“…This software is based on the 'finite element method' and is capable of performing the meshing of the problem geometry, the formulation of the problem in this mesh, the solving and the postprocessing of the results. This software has been used to model membrane and fixed-bed reactors with satisfactory results in previous works [23,40,43].…”

Modelling of hydrogen perm-selective membrane reactors for catalytic methane steam reforming

“…This software has been found to provide accurate coupling between model balances in previous works regarding membrane reactor modelling [3,37]. The number of elements used to solve the model was increased stepwise until a grid independent solution, which was obtained with 1200 quadrilateral elements.…”

“…This equation, when coupled with the mass and energy balances, provides the velocity and pressure gradients in the bed modified by the influence of the reaction and the membrane. Moreover, Brinkman equation can model deviations from ideal plug flow in packed beds (important for D R /d P < 10), by using a suitable radial porosity distribution function [36,37] (Table 4). The first term of Brinkman equation contains the pressure and viscous transport terms, whereas the second term accounts for the energy dissipated by friction with the bed solids.…”

Simulation and control of water-gas shift packed bed reactor with inter-stage cooling

“…Not to mention that the software has been used to model packed bed reactors with satisfactory results in previous works [19]. Notice that in this work we sub-divide the reactor length into 11 sub-sections of equal lengths to capture the effects of temperature and concentration distributions along the reactor (the actual model should be in PDE form).…”

“…The MSC FB-FF structure (figure 5) can be reduced to the same structure as that of the conventional single-loop feedback-feedforward control. One can derive an equivalent MSC-based feedforward controller as follows: Equation (19), F * ss denotes the optimised static feedforward controller while F msc denotes the MSC-based feedforward controller, i.e., the subscript msc is used to differentiate it from the conventional feedforward controller in figure 4. The formula for obtaining static the feedforward is obtained via the proposed method in [9].…”
