Study of heat treatment and cooling rate of oil mixtures transported by “Kumkol-Karakoin-Barsengir-Atasu” pipeline
Transportation of Kazakhstan waxy crude oil mixtures through long distance pipelines, such as “Kumkol-Karakoin-Barsengir-Atasu” entails various difficulties due to its composition. One of the most effective way to improve rheology is using heat treatment. The objective of this work is to investigate the effect of heat treatment on the rheology of oil mixtures and wax deposition tendenc in addition, to studying the influence of cooling rate and kinetics of wax crystallisation in accordance to the JMAK (Johnson-Mehl-Avrami-Kolmogorov) theory. The results indicate that increasing the value of heat treatment leads to improvment of rheological parameters of oil mixtures and a decrease in wax deposition but no change to the shape of crystals.
