Bitumen fluidizing

Cold Applied Coatings/Adhesives. Cold appUed BUR appHcations do not require heating to fluidize the bitumen on the job. Simple appHcation and economical maintenance ate primary considerations. Bitumens are Hquefied by dissolving in a solvent (cutbacks) or dispersing in water... 

After hot water extraction, crude bitumen is upgraded into synthetic oil fractions by either delayed coking or fluidized coking. A representative product yield from direct coking of Athabasca oil sand bitumen is provided in TABLE 12-7. 

In the process (Figure 8-10), the preheated feedstock (which may be whole crude, atmospheric residuum, vacuum residuum, or bitumen) is injected into a stream of fluidized, hot catalyst (trade name ArtCat). Complete mixing of the feedstock with the catalyst is achieved in the contactor, which is operated within a pressure-temperature envelope to ensure selective vaporization. The vapor and the contactor effluent are quickly and efficiently separated from each other and entrained hydrocarbons are stripped from the contaminant (containing spent...
