Title: A process for the treatment of liquid sulphur
IPC: C01B17/02
Filed: 1956-02-13
Abstract: <PICT:0792560/III/1> In the recovery of sulphur, produced in the Claus process, by washing the reaction product gas in a tower with liquid sulphur, the sulphur is recirculated from the bottom of the tower to the top thereof, and is simultaneously cooled, by means of an injector device operated by a gas and/or liquid vaporizable at the temperature of the liquid sulphur, said gas or liquid being at a temperature lower than that of the liquid sulphur.  The sulphur may be cooled from about 150 DEG  to 125 DEG  C.  Super-heated water at a temperature of 110 DEG  C. together with steam may be employed. Hydrogen sulphide may be burned with air in a steam boiler and the resulting gas, at a temperature of about 320 DEG  C., passed through a catalyst chamber to produce a sulphur-containing gas at a temperature of about 450 DEG  C.  As shown, this gas passes through inlet 1 into a scrubbing tower 2 fed with liquid sulphur through inlet 3, and the residual gas passes through outlet 6, after which it can be used for drying parts of apparatus, &c.  The resulting sulphur passes through outlet 4 to a sump 5, where it is cooled and drawn up tube 11 as a mixture with steam by the injection of a mixture of superheated water and steam through pipe 9, whereafter it is separated by means of baffles 12 and returned to tower 2 via inlet 3. The remaining steam passes through outlet 13, after which it can be used for distilling aqueous ammonia or hydrogen sulphide.

Abstract: <PICT:0966653/C1/1> <PICT:0966653/C1/2> To change the optical density of all or a portion o a phototropic glass article, the article in addition to being exposed to actinic radiation as known per se has the temperature changed. Preferably the temperature is changed to a value different from ambient temperature and the optical density is decreased by increasing the temperature.  As shown in Fig. 2, a glass pane 10 of phototropic glass made from glass as disclosed in Specification 950,906, is coated with a thin transparent electrically-conductive metal oxide coating 12 having terminals 14, 16 applied to opposite portions which are connected by wires 18, 20 to a variable transformer 22.  Regulation of the applied voltage to adjust the current through coating 12 and thereby the temperature of the glass 10, may be manual or by control circuits utilizing a photo-cell based at the desired level of illumination. Conventional heating means below the window or a radiant heater on the glass may be utilized in place of the coating 12. As shown in Fig. 3, signs may be built up by applying metal oxide films to a glass pane 40 in the form of elements 42, 44, 46, 48, 50, 52, 54 and 56 to form letters with metal contacts 58 at the ends of each element connected by wires 62 to terminals 60 connected to a source of electrical energy incorporating switches 64, 66, 68 for each letter.
