Title: Improvements in or relating to a process for separating ammonia and hydrogen chloride from ammonium chloride
IPC: C01B7/05
Filed: 1953-09-01
Abstract: In a continuous cyclic process for the production of hydrogen chloride and ammonia from ammonium chloride, wherein ammonium chloride is added to a melt of an acid sulphate and a heatstable iner organic stripping fluid is passed through the melt first to strip hydrogen chloride therefrom, and then, at a higher temperature, to strip ammonia therefrom, the fluid point of the melt is maintained below the temperature at which hydrogen chloride is stripped by introducing free or combined water or steam into the melt in amount 0 05 to 1 per cent of the weight of stripping fluid passed per cycle. The process particularly described is that of Specification 716,754, wherein NH4Cl is mixed with a bisulphate melt in amount 0.15-0.75 mole per mole, the melt is circulated through an HCl stripper at 220-270 DEG C. then through an NH3 stripper at 330-380 DEG C., HCl and NH3 are recovered from the respective strippers, and the bisulphate is recycled, but it is stated that the process may be effected without circulation of the melt.  The stripping fluid may be chlorinated benzenes or diphenyls, and the liquid should be dried, e.g. by calcium chloride or activated alumina, before heating prior to recycling.  The water may be added continuously or periodically to the melt or with the stripping fluid, as wet ammonium chloride, as aqueous concentrated sulphuric acid, or as sodium bisulphate monohydrate, but preferably steam is added to the stripping fluid or melt entering the NH3 stripper.  The bisulphate may be sodium, potassium, lithium, or ammonium, or mixtures thereof.  The preferred meit is a mixture of sodium and ammonium bisulphates prepared from sodium bisulphate mono-hydrate and ammonium sulphate by stripping of moisture and excess ammonia at 360 DEG C. with an organic vapour.

Abstract: 1,270,791. Measuring dimensions photoelectrically. BRITISH IRON & STEEL RESEARCH ASSOCIATION. May 2, 1969 [May 23, 1968], No. 24627/68. Heading G1A. Apparatus for detecting or measuring a transverse dimension of an elongated object comprises a lens adapted to produce an image exhibiting said dimension in the zone of a detector, a first elongated stop aperture located at the optical centre of the lens and extending in the direction of the dimension, and a second elongated stop located at the focus of the lens and extending in the same direction as the object. The second stop may be an aperture or a mirror. The stops may be rectangular or other shape with parallel sides. Various embodiments relating to measuring the diameter of a hot bar (which may be illuminated from behind) as it emerges from a rolling mill are described. In each embodiment the lens comprises a doublet lens with the first stop positioned between the lens elements. Various methods of scanning the image are detailed. In one form a vidicon camera is used. In another a slotted drum rotates to pass slots in front of a photo-cell. In other forms the image beam is deflected by a rotatable mirror to scan past one or two photo-cells each having a slotted mask in front of it. If two photo-cells are used they are arranged to produce pulse outputs timed such that if the bar is of the anticipated diameter the trailing edge of one pulse coincides with the leading edge of the other, variations in diameter being measured by known pulse shaping and timing equipment not detailed. The scanning mirror may be at the focus of the lens and replace the second stop and may comprise a rotating mirror drum. A reference object may be included and directed by a further lens on to the mirror so that the object and the reference object are scanned alternately. This allows the detector to be checked e. g. for drift. In event of error an alarm may be sounded or the drift may be corrected manually or automatically.
