The Membrane Library is an example Model Library provided with AVEVA Process Simulation. It provides a membrane reactor model for the rigorous simulation of reactions within a semi-permeable membrane. It also includes two example replaceable permeation submodels for modeling Palladium and Polymer membranes.
We have designed this Model Library to be used in conjunction with models from the Process Library.
Because this Model Library is an example Model Library, you must first import it into AVEVA Process Simulation to use its models in your simulations. You can import this Model Library from the %userprofile%\My Libraries\Examples folder.
The following table lists the models that are available in this Model Library. The table includes very brief descriptions for each model. The Model Help in the AVEVA Process Simulation user interface contains more detailed information for these models. See Open the Model Help for a Model Type or Model Library for more information.

|
DefPerm |
Submodel |
Represents a replaceable submodel for calculating permeation rates in the membrane reactor (MR) model. It returns a Flux vector in the unit of measure (UOM) kmol/sec-m2. |
|
MemDPCole |
Submodel |
Represents a replaceable pressure drop model for rigorous pressure drop calculations in the MR model. We recommend that you use this submodel to calculate the shell-side pressure drop of a sweep gas. You can also use it to calculate tube-side pressure drop for a membrane separator. We recommend that you use the Process.RxnDPErgun submodel for rigorous tube-side pressure drop with a catalyst packing. |

MR |
Model |
Models a shell-and-tube membrane reactor (MR) or separator. A membrane reactor contains a bank of semi-permeable membrane tubes. The selectivity of the membrane tubes allows a subset of the reaction products to permeate from the main reaction volume and increase overall reaction conversion (by Le Chatelier’s principle). Reaction and permeation submodels define the reaction kinetics and membrane characteristics. |

MRElem* |
Submodel |
Combines the reaction and permeation data for each discrete element in the MR model to calculate reaction and flux variables. |
|
PdMem |
Submodel |
Provides an example permeation submodel that you can use with the MR model. The flux calculations are for a metallic, hydrogen-based palladium membrane. The specific parameters are taken from Shu et al.. |
|
PolyMem |
Submodel |
Provides an example permeation submodel that you can be use with the MR model. The flux calculations are for a polymer-based hydrogen-selective polybenzimidazole (PBI) membrane. The specific parameters are taken from Radcliffe et al. |
* Only Model Writers can view these submodels.
