    Abstract: A compressor generates compressed air. Iron powder is provided in a deoxidizing chamber. The compressed air is supplied to the deoxidizing chamber such that the compressed air reacts with the iron powder to form iron oxide, so that oxygen contained in the compressed air is reduced to obtain remained nitrogen gas.

    Abstract: A process is described in which an elastic fluid is contacted with a particulate solid. This comprises providing a substantially vertical elongate tubular containment zone (1) containing a charge of the particulate solid (5), the volume of the containment zone (1) being greater than the settled volume of the particulate solid (5). An upper retainer means (3) is mounted at the upper end of the containment zone (1), the upper retainer means (3) being permeable to the fluid but adapted to retain particulate solid (5) in the containment zone (1). A follower means (4) is movably mounted in the containment zone (1) beneath the charge of particulate solid (5) for movement upwardly from the lower end of the containment zone (1) upon upward flow of elastic fluid through the containment zone (1) at a rate beyond a threshold rate. In the process the elastic fluid is caused to flow upwardly through the containment zone (1) at a rate which is sufficient to cause particulate solid (5) to rise up towards the upper end of the containment zone and form a cushion of particulate solid (5) against the underside of the upper retainer means (3). This rate is in excess of the threshold rate so as to cause the follower means (4) to move upwardly until it abuts against the underside of the cushion of particulate solid (5). The invention also provides an apparatus suitable for carrying out such a process and a method of loading a particulate solid into a substantially vertical tube.

    Abstract: A chemical reactor for catalytically processing a fluid feed stream comprises a reactor vessel incorporating a structured catalyst bed, and additionally comprises one or more catalytically active, fluid-permeable seals provided in gaps between the catalyst bed and the walls of the reactor vessel to treat portions of the fluid feed stream otherwise by-passing the structured catalyst for treatment.

    Abstract: The device is arranged in a process engineering column (10) and serves in particular for the guiding of liquid. This device includes at least two parts (1, 2) made of sheet metal and releasably connected to one another. A recess (12) is arranged in the one part, the sheet metal part (1) of a first kind, and an elevation (21) fitting into the recess is arranged in the other part, the sheet metal part (2) of a second kind. The two sheet metal parts are held in a secured position by a hook connection between the recess and the elevation. The recess and the elevation form a single pair or one pair among several and the sheet metal parts have planar regions lying on top of one another in the neighbourhood (120, 210) of the pair or of each pair respectively.

    Abstract: A hydrocarbon-containing feed, e.g. naphtha, is converted in a treatment plant (1), in particular a refinery or olefin plant, into desired olefins, e.g. ethylene and propylene. At least part of the fractions comprising relatively long-chain olefins, in particular olefins having at least four carbon atoms, obtained from the treatment plant (1) is passed to an olefin conversion stage (12). In the olefin conversion stage (12), for example, a catalytic reactor, in particular a fixed-bed reactor, at least part of the relatively long-chain olefins is converted into relatively shorter-chain olefins. To increase the yield of desired olefins, the olefin conversion stage (12) is preceded by a paraffin/olefin separation stage (23) wherein the feed stream is separated into a paraffin stream, e.g., a stream comprising butane and pentane, and an olefin stream, e.g,. a stream comprising butene and pentene, e.g., by extractive distillation. The paraffins obtained are recirculated to the treatment plant (1), e.g., to the cracking furnace (3) of the olefin plant, and the olefins are fed to the olefin conversion stage (12).
