This example is adapted from an example for VMG's VMGSim process simulator and represents a natural gas liquefaction process as represented in this PFD from VMGSim:
The names in the Alph case roughly correspond to those in the VMGSim example except 'f' is used for the fluids, rather than the 'S' for streams. Thus stream 'S6' in the PFD would be represented by fluid
'f6' in Alph.
