Abstract (en)

A steam cracker system, for processing of saturated hydrocarbons, comprises a heat exchanger/reactor ,in which the cracking product is used as heat transfer medium for the transformation reaction of 4-8C (preferably 4-5C) unsaturated hydrocarbons. An apparatus for the cleavage of saturated hydrocarbons comprises a thermal cleavage reactor (especially a cracking oven (2)), feed ports for hydrocarbons and steam, a reaction mixture take-off line leading to a cooler (especially a quench-cooler (5)) and a separator for the mixture. The system also has a feed (12, 30) for mainly unsaturated 4-8C (preferably 4-5C) hydrocarbons leading into a heat exchanger (28) in the low temperature part (preferably 500-750[deg]C) of the oven (2) and/or into a heat exchanger (7, 21), a line (6) leading to this heat exchanger from (5) for the reaction mixture from saturated hydrocarbons to be used as heat transfer medium, another line (6, 6a) for the reaction mixture (optionally from the cooler (5)) to another cooler (preferably a quench cooler (8)) and optionally a line (29) leading to another reactor (20) with catalyst, for the heated, unsaturated hydrocarbons.

Abstract (de)

Vorrichtung zum Spalten von vorwiegend gesättigten Kohlenwasserstoffen mit einem Reaktor, insbesondere Spaltofen (2), zum Erhitzen und Spalten mit einer Zuleitung (1, 3) für die Kohlenwasserstoffe und Dampf sowie einer Ableitung (4) für ein Reaktionsgemisch, die in einem Kühler, insbesondere Quenchkühler (5), mündet und einer Trennanlage für das Reaktionsgemisch, wobei eine Zuleitung (12, 30) für vorwiegend ungesättigte Kohlenwasserstoffe mit vier bis acht Kohlenstoffatomen, insbesondere vier bis fünf Kohlenstoffatomen, in einen Wärmetauscher (28) im Niedertemperaturteil, insbesondere mit 500°C bis 750°C, des Spaltofens (2) und/oder einen Wärmetauscher (7, 21) mündet, in welchem eine Leitung (6) für das Reaktionsgemisch nach den vorwiegend gesättigten Kohlenwasserstoffen als Wärmeträger aus dem Kühler (5) mündet und für das Reaktionsgemisch nach den vorwiegend gesättigten Kohlenwasserstoffen eine weitere Leitung (6, 6a), gegebenenfalls aus dem Kühler (5), in einem weiteren Kühler, insbesondere Quenchkühler (8), mündet und gegebenenfalls eine Leitung (29) für die erhitzten, vorwiegend ungesättigten, Kohlenwasserstoffe in einen weiteren Reaktor (20) mit Katalysator mündet und eine Trennanlage für ein Reaktionsgemisch nach den vorwiegend ungesättigten Kohlenwasserstoffen vorgesehen ist. <IMAGE>
