    Abstract: A tube plate for heat exchangers, particularly for hotgas coolers, wherein the gas inlet is exposed to gas temperatures exceeding 500* C. at high gas velocities, and wherein the gas inlet portions of the tubes conveying the gas that is to be cooled are double-walled and the two walls are annularly interconnected at the inlet end, the annular jacketing chambers thus formed each containing a coaxially inserted baffle tube for guiding the coolant, and the ends of said baffle tubes being fixed in a supplementary tube plate.

    Abstract: In the production of acetylene by subjecting hydrocarbons to high temperatures, the hot gas is quenched in a single stage by injecting a hydrocarbon oil boiling above 150 DEG C. in a volume ratio to gas (measured under standard conditions) of at least 1 : 100 without any appreciable cracking of the oil and separating the hot oil containing carbon black from the gas. The oil is preferably an aromatic oil and useful heat is extracted from it before its reuse; the carbon black content is preferably reduced to below 35% by weight e.g. by removing part of the oil and replacing this by fresh oil. The gas is preferably also later washed with an oil boiling in the range 80-450 DEG C. having a specific gravity below 0.95. The examples relate to the partial combustion of gasoline and of methane; reference is also made to heating hydrocarbons by electric discharge and exposure to hot flame gases. Specification 893,504 is referred to.

    Abstract: Hydrocarbons contaminated with carbon black, such as have been employed for quenching carbon-black-containing gases, are regenerated by passing them into contact with an indirectly heated and mechanically agitated bed of petroleum coke maintained at a temperature at least as high as the upper limit of the boiling range of the hydrocarbon. The separated carbon black may be withdrawn in the form of globular petroleum coke. The bed may be kept in motion by means of a stirrer or by employing an externally heated rotary kiln.ALSO:Carbon black prepared when hydrocarbons are cracked to produce synthesis gas &c., is washed from these gases with a hydrocarbon oil and the slurry formed passed to an externally heated, mechanically agitated bed of petroleum coke particles where the oil is vaporized and the carbon black withdrawn from the bed in the form of small globular particles.

    Abstract: In the preparation of olefines, particularly ethylene and propylene, by the high-temperature cracking of hydrocarbons the gaseous reaction stream is quenched by supplying laterally to the stream one or more compact jets of liquid in an amount sufficient to cool the gas by at least 100 DEG C. and with a pressure head such that the liquid penetrates the gas and is disintegrated therein. Cracking may be effected in the presence of a fluidized solid, at 650-850 DEG C., and 1-5 atmospheres, e.g. in reactor 1, to which oxygen is also supplied. Solids are removed from the product stream by cyclone 2 from which the gaseous product leaves by pipe 4. Jets of liquid, e.g. liquid reaction products boiling below 300 DEG C., are injected into the gas from jets 6. Preferably the product of (a) the ratio of the pressure head of liquid to that of the gas (measured at the point of entry to the cooling chamber) and (b) the ratio of the mean diameter of the liquid jet to that of the gas, should lie in the range 0.01 to 3. Where several jets are used such products may differ for each jet and the jets may be in different planes. The walls of the cooling chamber are preferably washed with the cooling liquid, e.g. from atomizer 7. Products leave by line 8.
