Description

Bonny Medium Crude characterized based on its true boiling points produces 0.02, 0.01, 0.085, 0.12, 0.14, 0.175, 0.1, and 0.365 Liquid Volume Fraction of Off Gas, Light Naphtha, Heavy Naphtha, Kerosene, Light Diesel, Heavy Diesel, AGO and Residue respectively.[1]

Expressed in percentage form reveals 2% Off Gas, 9% Naphtha, 12% Kerosene, 41% Diesel and 36% Atmospheric Residue of the total Liquid Volume Fraction.[1]

These values represent the maximum Liquid Volume Fraction of the different Distillate that can be gotten from the Crude at an ideal condition.[1]

Bonny Medium Data from OGJ 99 were originally published in 1983 as part of a series entitled "Guide to Export Crudes for the '80s":[2]
