Set Operation

Function : used to set the value of specific Process Variable (PV) in relation to another PV.

The set operation only can be used to define relationship The set operation only can be used to define relationship between the same PV in two like objects, i.e.: relationship between two temperatures of two different tstreams.

The dependent, or target variable is defined in terms of independent, or source variable according to the following linear relation: Y = MX + Bwhere: Y = Dependent (target) variableX = Independent (source) variableM = Multiplier (slope)u t p e (s ope)B = Offset (intercept)

RECYCLE OPERATION

Recycle Operation

Recycle Operation

Use this operation every time you need to recycle a stream.

The logical block connects the two streams around the tear stream (stream with temporary specification)(stream with temporary specification).

Before you can install the RECYCLE the flowsheet must have l t d Th t th d t b l f b thcompleted. That means there need to be values for both

the assumed stream and the calculated stream.

Once the Recycle is attached and running, HYSYS compares the two values, adjusts the assumed stream, and runs the flowsheetagain. HYSYS repeats this process until the two streams match g p pwithin specified tolerances.
