Medium Sized Wax Flow Loop for Live Oil

Manufacturer: Vinci Technologies
Model Number: Wax-Eval MS150

Wax deposition inside tubular and pipelines reduces the effective flow area, increasing the pressure drop and potentially causing complete blockage. Therefore, it is important to fully understand the oil’s behaviour throughout the pressure and temperature path from the formation to the production facilities. The Wax Eval MS 150 is a medium sized wax deposition loop that exposes live oil to a range of heat fluxes and shear rates that would be expected in the flowline during actual production. It involves four main steps, namely, the charging of the live oil, the thermal pretreatment of the oil, the cooling and the ungelling. It enables to determine the WAT of the oil sample, assess efficiency of inhibitors, and estimate the wax deposition rate according to flow conditions. It also enables to calculate pigging frequency and pipeline restart pressure for gel breaking. Experimental data obtained with the Wax Eval are entered into a simulation software to get a representative model of the oil sample which can be used for real pipeline application.
