I have an oilfield project, where the crude has a realtively high wax content (5%-30%). I am looking for a way to keep the wax from dropping out while in tank storage and piping to loadout (to rail and truck).
I have been reading about eductors (NciWeb.net/tank.htm) and heating systems. I like the idea of educotrs, since i want to keep the BS&W in suspension as well (kill two birds...), but not sure if just "mixing" the tank will be sufficient to avoid paraffin deposision in tank bottom. Basically, will just maintaining 1 tank turn per hour be sufficient to avoid deposition? Or do i need to add heat to keep it avoid wax appearance temp (and related safety features for heating crude...)
I assume I'll need to heat trace the lines to maintain the piping above wax appearance temp regardless (since the lines are run intermittently for loading, etc), but again maybe fluid velocity will "clean" the lines to avoid buildup?
