Vapour-phase stripping of Lloydminster crude oil in a sloping-plate distillation tower / by F.L. Booth, R.E. Carson & D.S. Montgomery, Fuels and Mining Practice Division. : M38-1/84-1961E-PDF

"This experimental investigation was undertaken to examine the process of vapour-phase stripping of Lloydminster crude oil to yield a high-softening-point pitch, employing a sloping-plate distillation tower. The experiments and calculations described in this report demonstrate that, under the present operating conditions, the mechanism of pitch formation is almost entirely due to the distillation of the volatile components from the crude oil. The extent of thermal cracking of the pitch may, for all practical purposes, be considered negligible. Under these conditions it is possible to produce a pitch with a softening point in the order of 200°F (Ring and Ball), amounting to approximately 25% by weight of the crude oil feed. It is believed that the mechanism of the pitch formation is sufficiently well defined that operating conditions can be selected which will yield a 250°F-softening-point pitch with no coke formation"--Summary, page i.
