SDL-1000 Solid deposition flow loop


The SDL-1000 solid deposition flow loop is a lab-scale flow loop designed to study asphaltene & wax deposition under dynamic conditions to mimics real production and transportation condition. In other words, the loop permits the investigation of temperature, pressure, flow regime and shear rate effects on asphaltene/wax deposition behavior. Crude oil, live oil or even crude oil blends can be evaluated on the unit. Last, but not the least, inhibitor performance can be also assessed with the apparatus. For a complete description of the deposition process, the first crystals or solid particles in the fluid are accurately detected using a solid detection system based on laser light scattering. Then, a high pressure fouling cell enables to collect the solid deposit which remains on the internal wall of the pipe for further analysis and deposition rate measurement.
