Process Intensification of Dehydrogenation Reactions by Pressure Swing Reactor

Process intensification in duplex pressure swing adsorption

As an alternative to the pressure swing adsorption (PSA) based on the Skarstrom cycle or its variants, a novel two-bed PSA--called duplex PSA--has been proposed by Hirose and independently by Leavitt to get both products of high purities. Simulation and experimental studies on duplex PSA for CO2 capture indicate that CO2 can be enriched to 95 mol% of feed containing 20 mol% CO2 and 80 mol% N2. ...

Reactor modeling and kinetic parameters estimation for diethylbenzene (DEB) dehydrogenation reactions

Divinylbenzene (DVB) is produced by catalytic dehydrogenation of DEB at high temperature and atmospheric pressure. Ethylvinylbenzene (EVB) is produced as a useful chemical during dehydrogenation of DEB. Also some other liquid and gaseous by products is produced during dehydrogenation. A set-up has been developed to conduct the DEB dehydrogenation reactions experiments to prepare DVB at differen...

Robust Control of a Pressure Swing Adsorption Process

This paper presents the H∞ control of a pressure swing adsorption process. This separation process is characterized by periodic operations. The objective of the control is to assign the trajectory of the output system purity and to reject the perturbation on the inlet composition. The control design is synthetized from some Hammerstein model that approximates the cyclic process. The control sch...
