1.1This practice describes the procedure for the interconversion of the analysis of C5 and lighter hydrocarbon mixtures to gas-volume (mole), liquid-volume, or mass basis.
1.2The computation procedures described assume that gas-volume percentages have already been corrected for nonideality of the components as a part of the analytical process by which they have been obtained. These are numerically the same as mole percentages.
1.3The procedure assumes the absence of nonadditivity corrections for mixtures of the pure liquid compounds. This is approximately true only for mixtures of hydrocarbons of the same number of carbon atoms, and in the absence of diolefins and acetylenic compounds.
