摘要： The invention relates to a method for cracking hydrocarbons, especially for producing olefins, whereby a mixture consisting of hydrocarbons and water vapor is heated in a cracking furnace up to a temperature ranging from 750 °C to 900 °C, and the resulting cracking gas which contains hydrogen is immediately cooled after the heating process in a cracking gas cooler to a temperature lower than approximately 650 °C. If heavy products are present, the cracking gas is subsequently subjected to an additional cooling by quenching and is then liberated by separating out heavy oil and gasoline. Afterwards, water vapor is removed by quenching from the cracking gas containing light products. This cracking gas is compressed to at least 20 bar by a compressor, is liberated from residual water by drying, is cooled in a deep cooling installation, and is fed into a plurality of rectifying columns in order to separate out the light products. Selective membrane diffusion is used to extract a portion of the hydrogen from the cracking gas in the direction of flow of the process medium upstream from the deep cooling installation. The invention also relates to an installation for thermally cracking hydrocarbons, especially for producing olefins.

摘要： The invention relates to a device for introducing hot gas into a heating surface pipe of a waste heat boiler, comprising an outer pipe that is connected to the boiler wall, particularly to the bottom of the pipe. Said device also comprises an inner pipe or entry pipe, which has an admission section that is cylindrical or conically narrows, which is connected to the outer pipe via a rounded reversible cap while forming an entry opening for the hot gas, which is surrounded by the outer pipe at a distance and finally, which has a discharge section that is connected to the heating surface pipe. The device also comprises a coolant guiding pipe, which is placed between the outer pipe and the inner pipe and which extends into the proximity of the reversible cap, whereby the guiding pipe (4) is provided in the form of a force-transmitting component and is connected, in a removable or fixed manner, both to the inner pipe (5) as well as to the outer pipe (3) each time with at least three connecting ribs (7, 8), which are uniformly distributed over the periphery and which are provided for introducing or transferring forces.

摘要： A quench cooler or transferline heat exchanger for quenching the effluent from a thermal cracking furnace has an inlet connector between the cracking furnace tubes and the tubes of the quench cooler. The tubes of the quench cooler are arranged in a circular pattern of spaced tubes. The flow passage of the connector is configured to initially decelerate and then re-accelerate the gas. This involves a conical diverging diffuser followed by a radial diffuser and then an annular converging section. The cross-sectional transitions are smooth to avoid dead spaces and minimize pressure loss.
