    摘要: The instant invention is directed to a process for stripping of a residual component from a liquid having a viscosity of from 300 to 10,000 poises in which the liquid flows in the form of a ring flow supported by a gas stream flowing in the core, through a tube into a separator vessel, the tube having a continuous coil shape and a conduit diameter to helix diameter of from 0.1:1 to 0.04:1, the improvement comprising adding to the gas stream from 10 to 90%, by weight, of externally generated steam and/or an inert gas at an adjusted pressure of from 50 m bars to 1 bar in the separator vessel for a gas and/or steam velocity in the tube of from 100 m/sec to the speed of sound. The added gas and/or steam generates thorough transverse mixing in the liquid ring flow.

    摘要: A process for producing fibre-reinforced plastic tubes outfitted with flanges, wherein a tube is continuously knit and coated with a duroplastic material in free-flowing form, and the duroplastic material is subsequently hardened. The application of duroplastic material to the knitted tube is halted at intervals for periods which, allowing for the particular rate of production of the plastic tube, correspond to the period of time in which a piece of knitted fabric sufficient for the production of two flanges is produced. The uncoated piece of knitted fabric is cut in the middle and flanges are formed one at a time in a separate operation in which the knitted fabric is stretched radially outwards and impregnated with duroplastic material which thereafter hardens.
