Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a...
This model demonstrates how you can access and include external thermodynamic and physical property calculations in your simulation, using the Thermodynamics feature. The model shows how you can easily modify the predefined Plug-flow...
This modeling example applies the Transport of Diluted Species interface to model a separation process. A stream containing six different ionic species is divided into pure component streams by means of migrative transport in an electric...
Several factors influence a diesel particulate filter’s (DPF) efficiency and durability. Important issues include the removal of soot particles from the filter membranes and the influence of thermal stress on the ceramic structure,...
Thermal dispersion in a porous medium results from the combined effects of heat conduction in the fluid and solid phases, and from convective transport in the fluid. In chemical process engineering, the modeling of thermal dispersion is...
Chemical vapor deposition (CVD) is an important step in the process of manufacturing microchips. One of the common applications is the deposition of silicon on wafers at low pressure. Low pressure reactors are used to get a high...
This model describes a common piece of equipment from the chemical and automotive industries: the catalytic converter for exhaust streams. It investigates coupling free and porous media with chemical reaction kinetics. The model...
In this example, a fluid carrying several chemical components is pumped into a detector compartment. A wire in the center of the detector is heated through Joule heating, which is supposed to detect changes in density through convective...
In concentrated gases and liquids, where the concentrations of species are of the same order of magnitude, there is no obvious solvent-solute relationship. Fick’s law for diffusion accounts only for one-way solute-solvent interactions...
This model considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is...
