A method of estimating the amount of hydrogen required to upgrade residual oils and tars [electronic resource] / B.I. Parsons, Fuels Research Centre. Ottawa : Queen's Printer, 1968. v, 24 p. : charts Technical bulletin ; TB 100 Cover title. "March 1968." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 20-21). “The hydrogen required to refine (by hydrogenation) a high-residuum oil is the sum of the hydrogen involved in four separate processes: (a) the hydrogen added to the residuum material to lower the specific gravity and improve hydrocarbon quality, (b) the hydrogen consumed in the removal of impurities, and the hydrogen removed from the system in the course of processing by the formation of (c) gases and (d) coke. In the following article a method is described for estimating the amount of hydrogen required in each step. The results of general (nominal) calculations for feed stocks of specific gravity 1.04, 0.98, 0.963 and 0.936 are presented in graphical form. Major factors taken into account in the calculations are the volume yield and specific gravity of the liquid product and the composition of the gases formed. Interpolation of the graphs for the preparation of estimates of hydrogen requirements for particular feed stocks and products is easy and quick. A typical application of the method to the processing of whole-crude and coker distillates from the Alberta Bituminous Sands Deposits is discussed"--Abstract, p. i.
