Issues with reaction category settings in Aspen?
Thread Content
In Aspen, when setting up reactions, there are options such as GLHHW-1, LHHW, POWERLAW, and EQUILIBRIUM. I would like to know what meaning these four reaction types have, and what kind of reactions they represent. Is this explained in the Aspen user manual? Thank you
The User Guide explains that the flow rate for reaction control and the equilibrium reactions of non-electrolytes can be specified using a Reaction ID; these can be found in the sections on kinetic reactors and pressure relief calculations. These applications include RadFrac, RateFrac, and BatchFrac for reactive distillation, as well as RBatch, RCSTR, and RPlug for reactor models based on kinetic principles. The Pressure Relief model is used for pressure relief calculations in reaction systems. The reaction kinetics of flow-rate-based reactions are described using one of the following expressions: power-law kinetic model, or the Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic model. The latter is not suitable for reactive distillation systems. There are also user-defined kinetic models available
