K factor (crude oil refining)
The K factor or characterization factor is defined from Rankine boiling temperature °R=1.8Tb[k] and relative to water density ρ at 60°F:
K(UOP) =
![{\displaystyle {\sqrt[{3}]{1.8Tb}}/\rho }](https://wikimedia.org/api/rest_v1/media/math/render/svg/d1b8f69a82faa3736e7efd4c318d2c982c214093)
The K factor is a systematic way of classifying a crude oil according to its paraffinic, naphthenic, intermediate or aromatic nature. 12.5 or higher indicate a crude oil of predominantly paraffinic constituents, while 10 or lower indicate a crude of more aromatic nature. The K(UOP) is also referred to as the UOP K factor or just UOPK.[1]
