Effects of Shear Rate and Inhibitors on Wax Deposition of Malaysian Crude Oil

Wax deposition can cause a serious problem in crude oil flow assurance, especially in deep water operation due to the long chain of n-paraffin. This paper examines the effects of two factors on the deposition process, which are shear rate and different types of inhibitors. 10 mL of four different ty...
