Latest SysCAD Version: 25 October 2024 - SysCAD 9.3 Build 139.36522
Related Links: ChemApp SysCAD Project Workflow
Formally released as part of Build 139 (first available as BETA version in Build 138). The ChemApp SysCAD TCE option and models documentation is for the latest version of SysCAD.
General Description
The ChemApp Side Calc model allows the user to 'call' the ChemApp solver to determine the state of a defined SysCAD stream/s. The user defines the SysCAD stream/s of interest, and the unit will then determine the equilibrium conditions of the resulting stream at the user defined conditions such as temperature or enthalpy. This is similar to the use of the ChemApp Reactor using the Side Calc model option.
The model has no links to any other models in SysCAD. Therefore, this model is not a part of any SysCAD network, but is a stand-alone calculation that allows the user to check the status of a stream.
Notes
- The user MUST have added and configured a ChemApp Model Configuration unit in the SysCAD project before this unit can function.
- The user MUST have installed a version of ChemApp on their computer to make use of the ChemApp functionality in SysCAD. Please see gtt-technologies.de for more information.
Diagram
The diagram shows the default drawing of a ChemApp Side Calc unit model. For side calculations with multiple incoming streams and containers, the combined stream pressure will be set to the lowest pressure of the incoming streams or containers that contain a flow or mass, respectively.
Inputs and Outputs
There are no connections to this unit.
Model Theory
The ChemApp Side Calc Model uses the ChemApp algorithms and data to determine the status of the defined stream/s.
Mapping of the SysCAD to ChemApp streams is done via Species Mapping.
The ChemApp Side Calc model allows the user to 'call' the ChemApp solver to determine the state of a defined SysCAD stream/s. The model has no links to any other models in SysCAD.
- User defines the stream/s to be analysed by the ChemApp Side Calc model.
- The SysCAD feed stream(s) using SysCAD species is converted into ChemApp "Input" using ChemApp Species. The species mapping is defined in the corresponding ChemApp Model Configuration unit model.
- The ChemApp Side Calc calls the ChemApp algorithms to determine the status of the mixture using the converted ChemApp "input" data.
- The ChemApp results are displayed in the "output" tab using ChemApp species.
- The results are NOT converted into SysCAD species.
NOTES:
- The side calculation mixed feed stream pressure is calculated as the minimum pressure of all incoming streams.
- The Input, Output and Diff tab pages are displayed using ChemApp species, as defined in the database (.dat or .cst) specified in the corresponding ChemApp Model Configuration unit model.
- The species used in the SysCAD project are shown on the optional Sp pages, shown as part of the QFeed, QBypass, QUnmapped, QRxnProdBypass and QProd pages.
- The calculations performed are similar to using ChemApp directly, except the contents of the SysCAD stream are mapped to equivalent ChemApp species using the settings defined in the ChemApp Model Configuration unit model.
WorkFlow
The suggested workflow for configuring the model is:
- Make sure the project contains at least one of the ChemApp Model Configuration model, and the model is loaded with the correct ChemApp database file you would like to use for the side calculation.
- On the ChemAppSideCalc tab page, type in the name of the SysCAD stream/s or content you wish to evaluate (e.g.: P_001.Qo OR TNK_001.QFeed). In Build 139 or later, multiple streams with multipliers can be specified.
- Choose when to perform the calculation.
- On the TCE tab page, select the correct ChemModel (to match step 1) (Note: In older builds, this selection was made on the ChemAppSideCalc tab page).
- Choose the Target Calculation OpMode and fill in the required information based on the mode selection. (Note: In older builds, these selections were made on the ChemAppSideCalc tab page).
- Perform an equilibrium calculation by pressing the "Calculate" button on the ChemAppSideCalc tab page or pressing Solve in SysCAD.
- The Results are displayed on the ChemAppResults and Output tabs.
Suggestions on how to use the results:
- The ChemApp Side Calc results can be used to assist with the configuration of with a SysCAD unit, normally with Reactions sub-model switched on. Based on the results of the ChemApp Side Calc, the reaction and reaction extents can be configured to match results from the ChemApp Side Calc. The user can use the Set Tag Controller to transfer ChemApp Side Calc results to the SysCAD unit reaction block.
