Abstract: A floating pipe includes a tube and a floater surrounding the tube. The dimensions of the floating pipe are such that the floating pipe fits inside a 40-ft ISO container, and the circumference of the floater, seen in cross section in a central part of the floating pipe, is a square, a truncated circle, a rounded square, a squircle, or similar shape.

Abstract: A hose includes a tubular section having an outer tube and an inner tube. The inner tube forms a liner for the outer tube. Apart from being connected by connecting means near both ends of the tubular section, the inner tube is unconnected to said outer tube.

Abstract: A flexible pipe (1) for transporting abrasive slurry, comprising a -tubular body (2) of a flexible polymer, such as rubber, and a multitude of coaxial, wear-resistant rings (3, 4, 5, 5) provided in the polymer along the length of the tube, wherein said rings and said tubular body have at least substantially the same internal diameter, and wherein thickness of the rings near their inner circumference is smaller over at least part of their circumference than the thickness of the rings near their outer circumference.

Abstract: A process for the preparation of methyl tertiary butyl ether (MTBE) in two stages:the first stage comprising the reaction of isobutene with methanol in the presence of an acid catalyst, yielding MTBE, while the second stage comprises firstly the conversion of normal-butenes present in the hydrocarbon flow, which remains behind after separation of the MTBE formed in the first stage into isobutene and secondly passing the mixture thus obtained to a reaction zone to form MTBE.Optionally an extra amount of methanol can be supplied to said reaction zone. Said reaction zone can be the same as that used in the same first stage or another one.

Abstract: An improved method for the preparation of cyclohexanol and/or cyclohexanone from benzene. Cyclohexanol and/or cyclohexanone is prepared by the steps of hydrogenating benzene to form a hydrogenation reaction mixture containing cyclohexene, unreacted benzene, and by-product cyclohexane, hydrating cyclohexene thus obtained to form a hydration reaction mixture containing cyclohexanol, unreacted benzene and by-product cyclohexane and/or oxidating this cyclohexene to form an oxidation reaction mixture containing cyclohexanone, unreacted benzene and by-product cyclohexane, recovering from said hydration reaction mixture the cyclohexanol product and/or from said oxidation reaction mixture the cyclohexanone product, and an organic phase containing unreacted benzene and by-product cyclohexane, and recycling unconverted benzene to the benzene hydrogenation step.
