Solving the mystery of components above C5

This post was last edited by Refiner on 2018-5-31 14:00. Question: Do the components above C5 refer to C1–C4 or C6?+
C5 is an indicator for liquefied gas; liquefied gas consists of C3 to C4, while components above C5 include C5 itself.
Generally speaking, when referring to components above C5, it indeed includes the C5 fraction! Of course, this isn’t inevitable either; they’re just conventional expressions!
The components we refer to as those above carbon five also include carbon five itself
Contains C5 and higher C6, C7……components
C5 and above is referred to as C5+. For example, the depentanized oil from reforming is gasoline of C6 and higher grades; it then goes to an extraction unit, where C5 becomes light naphtha. For example, when evaluating liquefied gas, it is required that the C5 content in it should not exceed 2.
