WAXEVAL SS200-Small sized Wax flow loop for live oil


The Wax-Eval SS200 is a miniature wax deposition flow loop in which live oil is circulated and subjected to a range of heat fluxes and shear rates representative of production flowline conditions. An experiment mainly consists of four stages, namely, live oil introduction in the loop, thermal pre-treatment, cooling and ungelling. It allows the evaluation of the wax appearance temperature WAT and wax deposition rate. The WAT defines the temperature at which viscosity increases and wax deposition begins; it is associated with a noticeable increase in pressure drop across the test deposition coil. The wax deposition rate corresponds to the wax deposition speed on the wall versus time and is calculated from the time rate of change of pressure drop in the test deposition coil. An optional restart test loop allows the determination of the gel strength (or yield strength) which is derived from the nitrogen pressure required to initiate flow in the loop. The experimental results can also be inputted into a simulation software to generate a thermodynamic model which can be utilized to simulate pipeline petroleum transport.
