Patent number: 5084079Abstract: A high-pressure hot separator for the separation of an overhead product from a process of high-pressure hydrogenation of coals, tars, crude oils, whose distillation and extraction products or similar carbon-containing feedstock such as heavy oils, low-temperature carbonization oils, extracts of heavy oil sands and the like, is downstream from the bottom phase reactors of the high-pressure hydrogenation. The separator is constructed from a vertically erected cylindrical pressure jacket having an upper cover, a lower cover, an inside adjacent thermal insulation member and a cylindrical wall insert. The overhead product is separated into a gas/vapor phase and a bottom product. A cyclone separator is installed in the gas/vapor space of the hot separator for improvement of the separation function.Type: GrantFiled: March 6, 1991Date of Patent: January 28, 1992Assignee: Veba Oel Technologie GmbHInventors: Heinz Frohnert, Klaus Niemann, Werner Riedel, Edgar Muschelknautz

Patent number: 5078549Abstract: A hydrocyclone has a separating part A with a diameter which toward its outlet end for the heavier fraction decreases gradually from a diameter 2 R.sub.a, with the radius being subject to the formula:R=R.sub.a .multidot..sqroot.1-x/1.This describes essentially the shape of a parabola, so that the separating part can practically be considered as a paraboloid. Achieved thereby is an optimum separating performance of the hydrocyclone.Type: GrantFiled: July 19, 1990Date of Patent: January 7, 1992Assignee: J. M.

Patent number: 4871147Abstract: An apparatus is described which serves for a pyrometallurgical processing of fine-grained solids suspended in high-oxygen gases, comprising a generally horizontally extending cylindrical vessel and a combustion shaft, which communicates with and vertically opens into the vessel which is provided with a gas outlet opening and with an opening for discharging molten material. An almost complete separation of the molten particles is effected in that the mouth of the combustion shaft tangentially opens into the vessel at the entrance of a spiral-shaped entrance passage, which opens into a discharge slot, which is formed in the shell of the vessel and which in the lower portion of the shell of the substantially cylindrical vessel extends substantially parallel to the longitudinal axis of the vessel.Type: GrantFiled: July 2, 1987Date of Patent: October 3, 1989Assignee: Norddeutsche Affinerie AktiengesellschaftInventors: Edgar Muschelknautz, Ernst Becker, Adalbert Bartsch, Lars Kersten, Georg Gospos, Gerhard Berndt

Patent number: 4570287Abstract: To clean the ballast bed of a railroad track, a wheeled vehicle movable over the ballast bed contains a blower for generating a positive flow of air and a suction flow. A suction port is located on the vehicle spaced a given distance above the ballast bed. A pipe section outlet is located around the suction port. The positive flow of air is directed through the pipe section outlet so that it provides a circular air flow about the downward projection of the suction port. The circular air flow sweeps the surface of the ballast bed and any refuse swept up is drawn into the suction port by the suction flow generated by the blower.Type: GrantFiled: May 23, 1984Date of Patent: February 18, 1986Assignee: Walter Schneider GmbH & Co.
