摘要：With the increasing need for crude oil and the improving processing capacity, refining of crude blending has become increasingly popular. This article studied the effect of blending refining at the various ratios by the dynamic equilibrium flash vaporization equipment. Nuclear magnetic resonance (NMR) and groups of oil analysis (SARA) were also applied to estimate the blended crudes at the optimal activation state at which the blending crude oils had the maximum distillation yield. The NMR of three groups of blended crudes have elucidated that the resin content at the optimal blended percentage is close to or lower than the theoretical value. And the resin content is obviously higher than theoretical value at the worst blending ratio. The asphaltene content increased, the residua became denser, and branching index decreased at the optimal blended percentage.
