The compound splitter is an ideal separation device; it splits specified compounds into pre-defined fractions. It can be useful for pre-converging flowsheet before putting the actual separation device in, or to represent separation devices for which no implementation is available but for which performance is known.
The compound splitter has one inlet and two outlets. The outlets are named main outlet and split outlet.
Compounds can be specified, and for each specified compound a split fraction can be specified. The specified fraction of the compound will then leave through the split outlet. The remainder, as well as all compounds that have not been specified, will leave through the main outlet.
A pressure drop can be specified.
The unit operates isothermally. With known pressure and temperature, equilibrium calculations are performed at the outlets.
