Template:TPSReactor Tab Page

Unit Type: {{{TPS}}}Reactor - The first tab page in the access window will have this name.

Tag (Long/Short)	Input / Calc	Description/Calculated Variables / Options
Tag	Display	This name tag may be modified with the Change Tag option.
Condition	Display	"OK" if no errors/warnings, otherwise lists errors/warnings.
ConditionCount	Display	The current number of errors/warnings. If condition is OK, returns 0.
GeneralDescription / GenDesc	Display	An automatically generated description for the unit. If text is entered in the 'EqpDesc' field on the Info tab (see below), this is displayed here. Otherwise, SysCAD will display the UnitType or SubClass.
Requirements
On	Tickbox	This allows the user to disable the {{{TPS}}} calculations, and the unit becomes a simple conduit with no calculations.
The following variable controls how vapour and solids are directed to the vent stream from the Reactor unit. The vent stream must be connected for any flow to occur.
Vent.SolidsMethod	None	All vapour will be sent to the vent stream, if connected. No solids will be included in the vent stream.
	Solids to Vent	All vapour will be sent to the vent stream, if connected. A user-defined fraction of the solids in the product stream will also be sent to the vent. If no vapour is present in the reactor, the vent stream will carry no flow.
	Vent Solids Fraction	All vapour will be sent to the vent stream, if connected. The user specifies the fraction of solids in the vent stream directly. If no vapour is present in the reactor, the vent stream will carry no flow.
SolidsToVent	Input	Only visible if Vent.SolidsMethod = Solids to Vent. The fraction of the solids in the product to be sent to the Vent stream (if connected).
Vent.SolidFracReqd	Input	Only visible if Vent.SolidsMethod = Vent Solids Fraction. The fraction of solids in the Vent stream (if connected).
OperatingP - NOTE: this pressure is applied to the (combined) feed, before sub-models (if any). DirectLink feeds, for example from Makeup Blocks, are excluded in determining the pressure. Typically the specified or calculated OperatingP pressure is also the unit operating pressure and outlet stream pressure, but in some models further changes are made to the pressure.
Method	AutoDetect	If there are any liquids AND no vapours present in the feed, outlet streams will take the highest pressure of the feeds. Else (e.g. some vapours present) outlet streams will take the lowest pressure of the feeds.
	LowestFeed	Outlet streams will take the lowest pressure of the feeds.
	HighestFeed	Outlet streams will take the highest pressure of the feeds.
	Atmospheric	Outlet streams will be at Atmospheric Pressure. The atmospheric pressure is calculated by SysCAD based on the user defined elevation (default elevation is at sea level = 101.325 kPa). The elevation can be changed on the Environment tab page of the Plant Model.
	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 pressure and temperature of the mixture, 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 required for any stream to contribute to the total flow when calculating the mixture pressure. For example, if the total feed to the unit 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.
PressureReqd / P_Reqd	Input	This field is only visible if the RequiredP method is chosen. This is user specified pressure.
Result	Calc	The actual pressure used for the sum of the feeds which will also be the outlet pressure (unless further model options change the pressure).
EB (Evaluation Block) ...
EvalSequence	Calc	The sequence in which the sub models (which are part of the evaluation blocks) will be calculated. The sequence is determined by the priority selection for the individual sub-models. Note: If the user chooses On-AutoSequence then SysCAD will determine the sequence of the sub-models. The sequence followed will be MU1, MU2, etc., RB.
Makeups	Input	The number of makeup blocks required. Extra dropdown options Makeup1, Makeup2, etc. will be added to allow these to be switched on.
MakeupX	List	This can be used to switch the Makeup Block (MU) on or off and prioritise it in relation to the other sub-models. 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.
Options
ShowQFeed	Tickbox	Allows the user to view the QFeed and associated tab pages, showing the properties of the combined feed stream. See Material Flow Section. This will be prior to any sub-model (e.g. reactions) actions or {{{TPS}}} calculations.
ShowQTCEFeed	Tickbox	Allows the user to view the QTCEFeed and associated tab pages, showing the properties of the combined feed stream before {{{TPS}}} calculations. See Material Flow Section. This will be after the actions of any sub-models (e.g. reactions).
ShowQProd	Tickbox	Only visible if Model = Reactor on the TEC tab page. Allows the user to view the QProd and associated tab pages, showing the properties of the products. See Material Flow Section. This will be after the actions of any sub-models and {{{TPS}}} calculations.
