---

First made available in Build 138 (as BETA version). Formally released as part of Build 139. The ChemApp FACTSage SysCAD add-on and models documentation is for the latest version of SysCAD.

General Description

The ChemApp Reactor model allows the user to 'call' the ChemApp solver to determine the state of a SysCAD stream. The composition, temperature and pressure of the 'Feed' stream are based on the feed to the unit. The unit will then determine the equilibrium conditions of the resulting stream.

The results can be applied to the product stream or just performed as a side calculation (similar to use of the ChemApp Side Calc Model).

Notes

1. The user MUST have added and configured a ChemApp Model Configuration unit in the SysCAD project before this unit can function.
2. 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 a drawing of the ChemApp Reactor unit, with Feed, Product and Vent streams. When the user inserts the ChemApp Reactor unit into a flowsheet, a different graphics symbol can be selected from a pull down menu. The streams may be connected to any area of the drawing without affecting the actual connection point as SysCAD ignores the physical position of the connection. For reactors with multiple incoming streams, the combined stream pressure will be set to the lowest pressure of the incoming streams that contain a flow.

The ChemApp Reactor can be incorporated into a SysCAD flowsheet, it can be connected with SysCAD inlet and outlet streams.

Model Theory

The ChemApp Reactor Model uses the ChemApp algorithms and data to determine the status of the equilibrium solution.

There are two mapping modes available, MapEach and MapCombined. The choice of mapping mode is linked to the ChemApp version. These are explained below.

• MapEach (always used with full version of ChemApp)

In this mapping mode, the streams are loaded individually into ChemApp. The mixing is therefore done in the ChemApp enthalpy context.

• MapCombined (only used with ChemApp Light)

In this mapping mode, the streams are mixed using the SysCAD enthalpy context prior to being loaded into ChemApp

The ChemApp Reactor can be incorporated into a SysCAD flowsheet, it can be connected with SysCAD inlet and outlet streams.

1. User connects the ChemApp Reactor with SysCAD input streams,
2. 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.
3. The ChemApp Reactor calls the ChemApp algorithms to determine the status of the mixture using the converted ChemApp "input" data.
4. The ChemApp results are displayed in the "output" tab using ChemApp species.
   • If the ChemApp Reactor is in Side Calc mode, the results are NOT converted into SysCAD species. (SysCAD stream outlet = sum of SysCAD inlet streams, no change will occur)
   • If the ChemApp Reactor is in Reactor mode, then the results are converted back into SysCAD species. Please see Species Mapping for more information.

NOTES:

• 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:

1. Make sure the project contains at least one of the ChemApp Model Configuration model, and the model is loaded with the correct ChemApp database you would like to use for the ChemApp Reactor.
2. On the ChemAppReactor Tab page, select the Model type
3. Choose the Target Calculation "OpMode" and fill in the required information based on the operation mode selection.
4. Select the correct "ChemModel" (to match step 1)
5. Set the operating pressure (and any other sub-models)
6. Perform an equilibrium calculation by pressing Solve in SysCAD.
7. The Results are displayed in the ChemAppResults and Output tabs.
8. Check and fix any species mapping issues. (ChemApp resulting species may change if the operating conditions change, so it is likely a change of temperature or feed composition will result in different ChemApp species.)

	RequiredP	Outlet streams will be at the user specified pressure.
IgnoreLowMassFlow / IgnoreLowQm	Tick Box	This option is only visible if the AutoDetect, LowestFeed or HighestFeed methods are chosen. When calculating the outlet pressure and temperature of the tank, SysCAD will ignore the low flow feed streams should this option be selected. The low flow limit is set in the field below.
LowMassFlowFrac / LowQmFrac	Input	This field is only visible if the IgnoreLowQm option is selected. This is the amount any stream contributes to the total flow. For example, if the total feed to the tank is 10 kg/s, and this field is set to 1%. Then any feed streams with less than 0.1 kg/s will be ignored in the pressure calculations.

If this is 'On' then the associated page, MUX becomes visible and may be configured. Note: This field is only visible if the entry for 'Makeups' is greater than 0. If there is one makeup then X=1. If there are two makeups, then X=1 and X=2, etc.

Content (Only visible if Filter is enabled)	All	No filtering of species based on element or name.
	Contains Any Element	This will display all species that contain any of the elements entered in their elemental definition.
	Contains All Elements	This will display only species that contain ALL of the elements entered in their elemental definition.
	Starts with ...	This will display species that start with the text entered based on the short or long species tag depending on the current SpeciesTag selection.

Select	Input	Only visible if Filter is enabled and Content is NOT set to All. The user specified Elements or text to filter the species list. Refer to Species Filter for more information and examples.
(The following tables (one per phase) display the ChemApp species from the selected database. The user can select any number of species.) (Each table has the following column (one row per ChemApp species):)
Select	Tickbox	The properties (selected on the ParamSweep tab) of the selected species will be reported when the Generate function (ParamSweep tab) is used.
