This option is used to 'hide' a percentage of one or more species from any reactions specified in the flowsheet. e.g. if the user is configuring a gold plant and they know that 10% of the gold cannot be recovered, they can 'hide' 10% of the incoming gold from any reactions. So, in a reaction file, the user can specify a reaction with an extent of 100%, and 100% of the available gold will react. The 10% of gold that is 'hidden' will bypass the reaction, but will still be visible to the user.

DLockup Tab Page

• This tab is only visible if Lockup has been included in the Configuration file AND Lockup has been enabled on the Plant Model - Qualities Tab AND Lockup.Action has been set to 'Create' or 'Modify', either in a Feeder or in a Pipe on the Qi tab.
• This tab page is for configuring the Lockup.

Each lockup species (selected on the Plant Model - Qualities Tab) will have the following field:
LockUpReqd	Input	The fraction of the species that is 'locked up', or not available for reaction.

Please see Lockup - Creating Lockup for more information.

Lockup Tab Page

• This tab is only visible if Lockup has been included in the Configuration file AND Lockup has been enabled on the Plant Model - Qualities Tab AND Lockup has been 'Created', either in a Feeder or in a Pipe on the Qi tab, upstream of the current unit.

Tag (Long/Short)	Input / Calc	Description/Calculated Variables / Options
Each lockup species (selected on the Plant Model - Qualities Tab) will have the following field:
LockedUpFrac	Calc	The fraction of the species that is 'locked up', or not available for reaction.
AvailableFrac	Calc	The fraction of the species that is available for reaction, or not locked up.
LockedUpQm	Calc	The mass flow of the species that is 'locked up', or not available for reaction.
AvailableQm	Calc	The mass flow of the species that is available for reaction, or not locked up.
An extra row Summary will be shown if two or more lockup species are available.
