Abstract: 1,261,609. Separating acid gases from hydrocarbons. LUMMUS CO. 13 Oct., 1969 [17 Oct., 1968], No. 50107/69. Heading BIL. In removing acid gases from a gaseous hydrocarbon-containing effluent containing acid gases and dienes as impurities e.g. obtained from the pyrolysis of ethane, propane, naphtha or gas oil, the hydrocarbon effluent is fed via line 10 into absorbing tower 11 where it contacts countercurrently with an aqueous amine solution, e.g. hexylamine, dipropylamine, propylene diamine, trimethylenediamine, ethylene diamine, triaminopropane, triethanolamine, dihydroxypropylamine, diethylamino ethyl alcohol, monoethanolamine, benzylamine, phenylethylamine, cyclohexylamine or cyclopentylamine, fed via line 12. The acid gases and dienes are absorbed into the amine and acid gas free hydrocarbon is withdrawn at 13. A hydrocarbon solvent, e.g. toluene or a low molecular weight naphtha, is added via line 14 and the resulting mixture led off at 15 and via mixer 17, and coalescer 19 to a settling chamber 21 maintained at a lower pressure than the absorbing tower 11 by a control valve 20. An aqueous amine phase essentially free of hydrocarbons is withdrawn through line 23, through heat exchanger 24 to a regenerator 25 where acid gas is withdrawn at 26 whilst the purified amine is recycled to line 12. The hydrocarbon phase is skimmed from the settler 21 and passed to a low pressure still 32 via heat exchanger 31. Gases released from the settler 21 are introduced via line 34 into the still 32 to aid in the recovery of the dienes. A diene overhead is withdrawn through 35 passed to condenser 36 and reflux drum 37. The liquid portion separated in reflux 37 is recycled to the still 32 whilst the gaseous portion is withdrawn by a steam ejector 41 or vacuum pump. A hydrocarbon solvent bottoms essentially free of dienes is then passed via 43 and the heat exchanger 31 into line 14 for recycling. In a modification Fig. 2 (not shown) wherein heavier hydrocarbons are to be removed in addition to dienes an initial separation of the heavier hydrocarbon phase may be effected before the addition of the hydrocarbon solvent. The separated hydrocarbon phase is added to the hydrocarbon phase formed after the addition of the solvent.

Title: Improvements in or relating to the Treatment of Textile Materials
IPC: D02G1/16
Filed: 1966-11-10
Abstract: 1,164,852. Textile treating apparatus. PLUTTE, KOECKE & CO. 10 Nov., 1966 [15 Nov., 1965; 15 Oct., 1966], No. 50530/66. Heading D1L. Apparatus for the continuous treatment, e.g. shrinking, steaming or dyeing, of textile yarn or thread with gaseous and/or liquid treatment medium comprises a chamber having at one end a thread inlet and an inlet duct for the medium and at the other end a thread outlet, the chamber being perforated for the outflow of the medium and the thread being delivered in such a way as to cause loose filling of the chamber. In the embodiment shown in Figure 1 the thread enters through opening 2 in nozzle 4 and is blown by means of the medium A into chamber 5 from which it is withdrawn after treatment through eyelet 6. The openings between spiral 8 are sufficiently small to prevent any thread escaping. As the chamber becomes filled with thread, the openings become covered and the resistance to flow of the medium increases until no more medium can flow into the chamber and thus the supply of fresh thread ceases. After a treatment period of desired length, the thread is withdrawn through eyelet 6 so allowing more treatment medium and thus thread to enter the chamber. Alternatively, as in Figure 3, the thread enters the chamber separately from the medium A which enters tangentially. For uniform filling of the chamber a thread guide 39 is provided which leads the thread between the largest and smallest peripheral portions of a pair of rotating conical rollers 25, 28 thus increasing or decreasing the withdrawal speed from a spool 22. The guide 39 is controlled by the difference in the pressure acting on the two sides of a membrane 38, the sides being connected to channels 40 and 41 of the chamber. The guide may alternatively be controlled by an axially movable piston controlled by the pressure at the inlet end of the chamber (Fig. 3a not shown). The thread may pass through a dye bath 106 (Fig. 4) and then between squeeze rollers 102 and 103 before being blown into the treatment chamber by heated air or steam from container 125. The chamber has a central region 112<SP>1</SP> connected by axially inclined openings 114 and 115 with axially disposed annular chambers 113 and 116 to 126. The yarn may be washed and/or dried by passing appropriate medium through selected annular chambers. Instead of a dye bath a multi colour printing device can be provided. Also the dye may be supplied in the first reached portion of the treatment chamber instead of there being a dye bath. Multi-coloured dyeing can be effected by subdividing the annular chambers for the introduction of several dyes in required proportions (Figs. 6a and 6b, not shown), or pipes may introduce the various dyes into the central region (Figs. 7a and 7b not shown). Several threads can be treated simultaneously.

As described, the apparatus for carrying out the method forms a compound surface on a pair of lenses 10, 12 using a pair of laps 26, 28, the lenses moving in circular orbits and the laps on the elliptical orbits. Each lens 10, 12 is secured to a block 16 held against rotation by pins 18, 20 of a holder 22, 24. Each holder is mounted on a shaft 134 carried by bearings 128, 134 in a respective A-shaped frame 120, 122 journalled in bearings 124 on a common shaft 108. Pneumatic or hydraulic cylinders 154 have rods 164 provided with noses 170 engaging recesses 174 in the frames A to urge them about the shaft 108 so that the pressure between the lenses and laps can be controlled. The shaft 108 is carried by a platform 94 which is moved with a circular translatory motion by being engaged by an eccentric 86 on a vertical shaft 82 rotated by a belt drive 78 from a motor 68, the shaft being mounted in a housing 56 on a shaft 54 which also has a pair of idler crank housings 101, 103 for idler crank mechanisms which, with the shaft 82, provide a three-point support for the platform. Each lap 26, 28 is secured by a clamp 30 to a respective arm 34 clamped to a shaft 212, 228. Each shaft is mounted in bearings 214, 216 in a frame 198 carried by a pivot shaft 194 on a lower shelf 184 of the machine. A motor 202 is mounted on the frame 198 and has a large diameter cam 232 which engages a roller 242 mounted on the shelf whereby the frame 198 is tilted to and fro about the pivot shaft and moves the laps in the direction of the minor axes of their elliptical orbits. A smaller cam 244 on the shaft of the motor 202 engages rollers 256, 260 on cams 248, 258 clamped to the shafts 212, 228 whereby the laps are moved to and fro in the direction of the major axes of their elliptical orbits, the combination of the movements derived from the cams 232, 244 moving the laps in substantially elliptical orbits simultaneously with the movements of the lenses in circular orbits. In another embodiment, the frame 198 is mounted on a universal joint. The cam 232 may be replaced by an elliptical cam which causes the laps to move in a "collapsed" elliptical path.
