Title: A Process for the Purification of Synthesis Gases.
IPC: C01B32/50
Filed: 1966-11-15
Abstract: 1,160,374. Purifying combustible gases. METALLGESELLSCHAFT A.G. and LINDE A.G. 15 Nov., 1966 [15 Nov., 1965], No. 51207/66. Heading C5E. Gases rich in CO 2 , at a pressure of at least 40 atmos., e.g. converted fuel gases, have their CO 2  removed by a three stage process. The gases entering at 10 are precooled at 1, e.g. by indirect heat exchange, until CO 2  begins to condense; they are then scrubbed at 3 at subzero temperature with an organic polar absorbent, e.g. acetone or methanol, which is regenerated by decompression in stages 6 . . . 8 and by stripping, e.g. with nitrogen, at 9; and they are then cooled to below the dew point of CO 2  in a tower 2 (at 4) by regenerated absorbent. Condensate from the precooler 1 is delivered at 39 to the base of the tower 2, from where used absorbent follows one of two paths; one is via heat exchangers 17, 14, 18, 19, in all of which it is cooled, one portion being returned to the scrubber 3 and another to the precooler 1 to prevent icing therein; the other path is through the regenerator 6 . . . 9 for recycling to the top of tower 2. Gases leave the regenerator at 23 and 30: at 23 they comprise mainly H 2  and CO, and may be recycled to the crude gas; at 30 (from stages 7, 8) they are mainly CO 2 , and are passed out of the apparatus by 31, 1. In a modification. Fig. 2 (not shown) intended for crude gases containing sulphur, absorbent only partly regenerated with respect to H 2 S is taken from a point in the stripper 9 and recycled to an intermediate point in the section 4, the rest of the apparatus being unchanged. In a specific example, in which the crude gas was obtained by steam-reforming a desulphurized light petrol, the converted gas at 110 atmos. pressure was cooled to -3 C. at 1, being contacted in the tower 2 with methanol which is at -60 C. at the top and -10 C. at the bottom. 17 is an ammonia-evaporator to make up cold losses.

Abstract: 1,134,393. Handling bobbins. DEERING MILLIKEN RESEARCH CORP. 2 Dec., 1965 [3 Dec., 1964], No. 51250/65. Heading D1F [Also in Division G1] Bobbins or quills 12, having been unwound e.g. at a winding machine 10 are inspected for yarn left thereon as they pass to a further position e.g. the automatic loading station of a spinning frame. The bobbins pass along a conveyor 20 to be inspected by a photo-cell 52 receiving the reflected light from a light source 51. If the bobbin has more than, say 2 inches of yarn therealong then the photocell 52 actuates via a circuit (Fig. 5, not shown) a solenoid operated air nozzle 24 to blow the bobbin into a container 22 or onto a conveyor. If there is less yarn on the bobbin it passes to a second photo-cell 54 which reacts to any yarn on the bobbin and actuates an air nozzle 28 which blows the bobbin into a container 26 or onto a conveyor. Bobbins with no yarn thereon travel the full length of the conveyor. The cleats on conveyor 20 have extensions to shield the light reflecting ferrules of the bobbins from the photo-cell.

A method for continuously measuring the proportion of a first constituent gas in a gas mixture comprises providing two sample streams in conduits 12, 14 of the mixture from an initial stream in a conduit 10, selectively removing the first constituent gas from one of the streams e.g. by absorption in a scubber 16, and then measuring and comparing using a sensor 18, the partial pressures of a second constituent gas in the two streams and relating the difference between the measured partial pressures to the proportion of the first constituent gas in the original mixture. The gas may be dried before the partial pressure measurement either in the conduit 10 or the conduits 12, 14. The total pressures in the conduits 12, 14 at the sensor 18 are maintained equal or in constant ratio and electrolytic cells are preferably used as the sensors. Where carbon dioxide is to be determined in a mixture of other gas it may be absorbed in one of the two streams by use of lithium or sodium hydroxide or a molecular sieve may be used. Anhydrous calcium sulphate may be used as a drying agent. A suitable sensor 18 is shown in Fig.5 in the form of a polerographic electrolytic cell 26 having two half portions 34, 36 disposed on opposite sides of a solid electrolyte 38 on which is mounted electrodes 40, 42 disposed in chambers 44, 46 through which the gas streams from the conduits 12, 14 pass. For measuring the patial pressure in oxygen the electrolyte may be zirconia and a heater 32 maintains the cell at a temperature preferably above 825 C. The voltage displacement of the cell due to the differences in oxygen partial pressure in the two streams, is measured and from this the volume of the first constituent gas absorbed in the scubber can be determined. A double cell sensor is also described having three chambers divided by two solid electrolyte layers each fitted with electrodes as in Fig. 5.

[Also in Divisions B1 and F2] A valve, which is designed for use in a draft beer dispensing system between the barrel to which pressurized gas is supplied and the dispensing tap Figs.5 and 6 (not shown), and which is adapted to minimize foaming in the dispensed beer by removing the pressurizing gas from the beer passing to the tap, includes a float 46 which carries a valve closure member 44 and is movable upwardly and downwardly along a guide 41 in response to the presence and absence respectively of beer within the valve housing 12, total absence of beer in the housing resulting in the closure member 44 firmly engaging its seat, and hence preventing gas entering the outlet line leading to the tap. To re-start the flow of beer, or upon the gas pressure exceeding a predetermined limit, a manually-operable relief valve 36 is actuated. Cleaning of the dispensing system can be effected by manual actuation of an outwardly spring-biased rod which normally abuts the valve member when the same is seated, but can raise the member from its seatings to permit the gas to pass from the housing to the tap.
