INSTALLATION FOR COMPRESSORLESS OXIDATION OF ROAD TAR FOR PRODUCTION OF BITUMEN Russian patent published in 1995 - IPC

FIELD: petroleum chemistry. SUBSTANCE: installation comprises an oxidation unit incorporating a reaction vessel with a bihyperbolic stabilizer, a heater, pipes and pipe fittings, and a unit for cleaning the exhaust gases of the oxidation unit. A mixing chamber installed on the housing of the reaction vessel is connected with the latter by a slot-shaped hole disposed in the plane of the larger bases of the stabilizer and ejector which is mounted on the mixing chamber and connected via a pump with the reaction vessel. The cleaning unit is connected with the oxidation unit and consists of a reaction vessel with a hyperbolic stabilizer provided with a mixing chamber which is installed on the housing of the reaction vessel and connected with the latter by a slot-shaped hole located in the plane of the larger bases of the stabilizer and an ejector installed on the mixing chamber and connected via a pump with the reaction vessel, pipes and pipe fittings. The ejector is disposed on the horizontal upper part of the mixing chamber at an angle of 45 deg. The mixing chamber is connected with the reaction vessel by two circulating pipes one of which connects the upper part of the mixing chamber with the lower part of the reaction vessel while the other one connects the middle part of the mixing chamber with the upper part of the reaction vessel. EFFECT: improved design. 3 cl, 1 dwg
