Experimental study on wax deposition of gas-liquid under intermittent flow

Abstract

This paper examined the wax deposition of gas-liquid intermittent flow in a flow-loop apparatus. In the study, increases in gas superficial velocity have been observed to result in decreases in the deposit mass. While the increases in liquid superficial velocity have been observed to result in increases first, then decreases. The deposit distributes along the pipe circumference, at first, the top is thinner and bottom is thicker, then deposit distributes uniform as the gas/liquid superficial velocity increases. In addition, the deposit thickness will first increase and then decrease with oil temperature increases, but decrease with the coolant temperature increases.
