Abstract (en)
[origin: EP0142043A2] The residues from the hydrogenation of heavy oils or very heavy oils, bitumen, tar, oils from oil shale or tar sand and the like, are subjected to a vacuum distillation at pressures from 0.01 to 0.6 bar. For an improved process engineering procedure in the vacuum distillation of such hydrogenation residues, these are subjected to a distillation under reduced pressure in a single- or multi-shaft screw machine. <IMAGE>
