Class Information
Number: 585/802
Name: Chemistry of hydrocarbon compounds > Purification, separation, or recovery > By plural serial diverse separations
Description: Subject matter wherein a feedstock containing the hydrocarbon material is subjected to a series of separation procedures which differ from each other in their mechanism, usually to separate the starting mixture into more than two components, to nullify the effect of more than one component, to free the recoverable material from a byproduct of the separation process, etc.
