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...

Optimization modeling and simulation of the autothermal reactor in the methanol production process was effectively done using the quasi –Newton scheme of optimization in Aspen Hysys 2006.5. The primary variables selected for this modeling were heat flow value of the following: Steam1;steam2; coolant1; coolant2; coolant3. After running the process optimization simulation, total cost was minimize...

in this paper, a batch hydrogenation reactor performance was modeled using a hydrodynamic and reaction sub-models. the reaction expressions were obtained from the information reported in literature. experimental studies were conducted in order to generate the experimental data needed to validate the model. the comparison between the experimental data and model predictions seems quite satisfacto...

The successful operation of a high-rate anaerobic reactor, up flow anaerobic sludge blanket (UASB) reactor depends on the prevailing physico-chemical and biological conditions during its operation. The wastewater characteristics and composition, the hydrodynamics of the process, and microbial activity are critical for achieving long term, optimal reactor performance. Modeling UASBs can be benef...

The modeling of thermal reaction furnaces of Sulfur Recovery Units (SRUs) is a rather complex problem since it involves different modeling scales such as the kinetic/molecular scale, the reactor scale, and the chemical process scale. This work introduces the multi-scale modeling approach to characterize the kinetic and reaction engineering scales for the thermal section of SRUs, involving the r...

The basic structure of a reactor physics laboratory environment simulation software, developed using object modeling technique (OMT), and based on the reactor point kinetic equation, is presented.

A method for scale up of UV/AOP reactors is outlined that uses bench scale testing to determine the UV dose required per log destruction (DL) of a particular contaminant. This can then be used in CFD Modeling to size a full-scale UV reactor and to test the reactor in performance trials. Methods for calculating dose based on the path length distribution in a UV reactor are given.

the application of neural networks to model a laboratory scale inverse fluidized bed reactor has been studied. a radial basis function neural network has been successfully employed for the modeling of the inverse fluidized bed reactor. in the proposed model, the trained neural network represents the kinetics of biological decomposition of organic matters in the reactor. the neural network has b...

Due to the diversity of fuel cycle simulator modeling assumptions, direct comparison and benchmarking can be difficult. In 2012 the Organisation for Economic Co-operation and Development (OECD) completed a benchmark study that is perhaps the most complete published comparison performed. Despite this, various results from the simulators were often significantly different because of inconsistenci...
