Two-Dimensional Modeling of a Packed-Bed Membrane Reactor for the Oxidative Coupling of Methane

Optimal startup operation of simulated moving bed chromatographic processes

SMB represents one of the widely established periodic adsorption processes and its periodic and nonlinear dynamics presents a significant challenge to the formulation and solution of the optimal startup issue. A multistage startup concept allowing to adjust operating conditions stage-wise is proposed. The startup problem is then formulated aiming at driving the system towards the reference cycl...

Mathematical modeling of a fixed bed chromatographic reactor for Fischer Tropsch synthesis

In this research, Fischer Tropsch synthesis (FTS) has been modeled in the fixed bed chromatographic reactor for the first time by applying a rather complex dispersed plug flow model for fluid phase and linear driving force (LDF) model for adsorbent. Model equations are dynamic, multi-component, non-linear and heterogeneous including reaction and adsorption simultaneously Complex kinetics fo...

The Moving Bed Biofilm Reactor

A new biofilm reactor for wastewater treatment, the moving bed biofilm reactor (MBBR), is discussed. A general description of the reactor is given. Results from investigations of different applications (carbonaceous removal, nitrification and nitrogen removal) when used for municipal wastewater treatment, are discussed. Design values are given and it is demonstrated that use of this reactor res...

Chromatographic parameter estimation for the model-based design of a sugar separating simulated moving bed process

Rare sugars are becoming increasingly interesting for many industrial applications, due to properties such as low energy content and potential pharmaceutical uses. D-psicose is one of the rare sugars with a future use as a sweetener and precursor for pharmaceuticals. It can be enzymatically produced from a cheap substrate, Dfructose. Because of the position of the thermodynamic equilibrium the ...
