Also, there are numerous special settings for special conditions e. Normally would change to other reactor for accuracy. It also provides a short outlook on possible optimization approaches.

A common way to model such reactions is to assume an ideal plug flow inside the tube. The usual models are also provided for additional component data and mixing rules. Rectification is used to separate ttutorial multiple substance mixture with columns. Feedback Privacy Policy Feedback. In comparison to an equilibrium-based model like implemented in the unit operations GIBS Gibbs free energy minimization and EREA equilibrium reactor based on given stoichiometries the KREA unit allows a reactor design when kinetic reaction data is available.

In addition to the usual gE models and equations of state, it is also easy to add and use custom K-value models. With local thermodynamic settings, different models can be applied within the same flow sheet. About project SlidePlayer Terms of Service. Clicking on the Connector icon in the main pallet, connect Input symbol to the Flash Drum tutoiral stream, and the Output symbols to the flash outlets.
