Using FSUB to Remove Some of a Stream's Contents By Difference in METSIM

FSUB is a mathematical function which can be used to set a stream's contents by difference between two streams.

" StreamNumberToHaveMaterialSubtractedFrom FSUB StreamNumberWithMaterialToDoTheSubtractionWith "

will change the contects of the StreamNumberToHaveMaterialSubtractedFrom stream by removing the mass of each component in the DoTheSubtractionWith stream.

It will remove the mass of each component if there is sufficient mass for the required amount to be removed, or leave none if there is not enough (it does not generate negative mass).
