dcterms: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 over the 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 a slurry that 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 over the temperature interval of 298-373 K.
