Rheological Properties of Nanofiltered Athabasca Bitumen and Maya Crude Oil

Original language description

Complex viscosities of Athabasca bitumen (Alberta, Canada) and Maya crude oil (Mexico) samples, slony with their permeates and retentates obtained by nanofiltration at 473 K through 5-, 10-, 20-, 50-, and 200-nm ceramic membranes, were investigated overthe temperature interval of 298-373 K. The pentaneasphaltene content of the samples varied from 1.5 wt% to 57.2 wt %, whereas the asphaltene-free composition of the samples did not vary from the feed composition (within experimental error). At temperatures of <323 K, part of the maltenes of both of these hydrocarbon resources is solid. The solid maltene fraction is a function of temperature. If this additional solid is taken into account, the experimental relative viscosities for both Athabasca bitumen-and Maya crude-related samples fall on a single master curve, over the entire temperature interval, irrespective of the asphaltene content. The rheological behavior of all feed, permeate, and retentate samples is consistent with that of
