New approach developed for estimating pour points of crude oil blends

Development of a viable crude transportation system that moves multiple crude oils requires knowledge of the crude blend pour points and other properties. The pour points of crude blend are generally not linearly proportional to the mixing-ratio of every individual crude. Reported approaches for estimating the pour points of crude blends require the pour points of every binary crude blend at a mixing-ratio of 1:1 or several compositional contents such as paraffin, resin, gas-benzene contents in the blends and viscosities at some temperatures. These requirements cause great difficulties in some cases when these basic data are unavailable as when, for example, no crude sample is available.A...
