Model Number: Wax-Eval SS200
The Wax-Eval SS200 is a small sized wax deposition loop that exposes live oil to a range of heat fluxes and shear rates that would be expected in the flow line during actual production. It allows for determining the wax appearance temperature WAT and the wax deposition rate. The WAT defines the temperature below which viscosity increases and wax deposit. The wax deposition rate defines the amount of wax which deposit on the wall versus time. The loop involves four main steps, namely, the charging of the live oil, the thermal pretreatment of the oil, the cooling and the ungelling. An optional restart test loop can be added to the system in order to measure the gel strength or yield stress which is used for estimating the start up pressure requirement for gelled oil in a shutdown pipeline. 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.
