Abstract: A port arrangement is configured for accessing a demountable component in an interior of an apparatus or container. The port arrangement includes an inner port having a port tube and forming a releasable connection with an internal component. The port tube of the inner port is guided through an outer port that is to an outer jacket.

Abstract: A reactor is described for the production of C2 to C8 olefins from gaseous oxygenate and H2O and one or more material flows containing C2 C4, C5, C6, C7, C8 olefin and paraffin at 400° to 470° C., wherein several reaction stages which the material flow can pass through from the top to the bottom, each consisting of a support base with a catalyst layer situated on it, are arranged in a closed, upright container.

Abstract: The burner has at least two fuel-carrying tubes which are arranged in parallel, the distance between adjacent fuel-carrying tubes being 5 to 30 cm. Each fuel-carrying tube is surrounded by a steam-carrying tube, which at its orifice end has a supply line for oxygen-containing gas. The steam-carrying tubes are surrounded by a common first cooling chamber through which cooling liquid is passed, the first cooling chamber constituting an annular chamber and extending into the area of the orifice ends of the steam-carrying tubes. Coaxial to the first cooling chamber a common second cooling chamber preferably is provided, which is surrounded by the first cooling chamber.

Abstract: For collection of dust from gases at temperatures up to 900.degree. C. and under presssures up to 20 bars by means of gas-permeable two-dimensional filter elements, an apparatus is proposed which comprises a pressure-resisting cylindrical outer housing, which contains a gas-tight pear-shaped inner housing, which is movably mounted in the outer housing by a means of a heat-insulating carrying structure and is provided with a tubular gas-outlet port and comprises a cambered bottom, which contains cylindrical filter elements. A pressure-confining gas-tight compensator is provided between the tubular gas-outlet port of the inner housing and the outer housing. Because the "pressure-confining" and "supporting" functions are separate, the internal components, which will be subjected to temperatures up to 900.degree. C., can be joined to the pressure-confining wall of the outer housing, which must not be heated above 200.degree. C.
