Patent EP-0030447-A1 (EP)
Inventor: JAGODZINSKI RICHARD F
IPC: B01D53/86
Filed: 1980-12-03
Abstract: A process is provided for producing elemental sulphur from a hydrogen sulphide and sulphur dioxide containing gas stream by a Claus type of catalytic reaction. The process is based on the discovery that the conventional Claus catalyst, in the presence of liquid sulphur and at pressures considerably greater than one atmosphere, is significantly active toward the Claus catalytic reaction. Thus, in accordance with the invention, increasing the pressure of the reaction in the presence of liquid sulphur increases both the catalytic activity and the elemental sulphur conversion. The process involves introducing a compressed hydrogen sulphide and sulphur dioxide containing gas stream into a catalytic reactor and reacting the gases in a Claus catalyst bed in the reactor to produce elemental sulphur under conditions of temperature and pressure such that water in the reactor exists only as water vapour and sulphur vapour is condensed in the catalyst bed, being removed therefrom as a liquid. The pressure within the reactor is preferably between 5 and 50 atmospheres absolute.

Abstract: Disclosed are overvoltage arresters comprising a columnar arrangement of arrester elements, insulating elements and conducting elements. The elements are arranged to provide a current flow in at least one plane extending transversely to the columns. The conducting frame elements connect other elements thereto which elements extend both axially and transversely of the columns. For an arrester including n conducting frame members per plane, n-1 arrester elements are arranged per plane of the columnar structure. The current connection between adjacent plane is made by an arrester element or by a conducting member preferably such that opposite current flows are obtained in adjacent planes. Overvoltage arresters according to the invention are particularly suited for using voltage-dependent resistors of the zinc oxide type alone or in conjunction with spark gaps. The columnar structure may be disposed in a customary insulating gas such as nitrogen or in a gas with particularly high insulating strength such as SF6.

Abstract: Production quantities of a multi-element holographic scanner disc are made by optically replicating a silver halide master disc one element at a time in a dichromated gelatin film. The dichromated gelatin film swells during processing. The swell (Δt) is monitored during production by determin- '  ing the shift in the angle of the Bragg surfaces within the gel. The angle of the replicating beam for each element is changed from that of the original reference beam to establish a Bragg angle α0 at exposure which will be tilted to the proper angle aSW after swelling in order to maximise the diffraction efficiency of the element at the original reference beam angle.

Abstract: A washing column for the continuous separation between a solid chemical formed in a liquid multi-component system, on the one hand, and the mother liquor in which the solid chemical is suspended, on the other. In a cylindrical working space a stationary, straight, plane washing front is maintained in a packed bed of the solid chemical substance between the mother liquor, on the one hand, and a melt of the solid chemical, on the other. According to the invention, the washing column is double-walled to form an enveloping space, which contains a heat insulating medium and can be pressurized to conform to the pressure within the column. This construction permits the use of a relatively thin, glass inner wall of uniform wall thickness and inner surface. This renders the column resistant to corrosive chemicals, reduces the effect of heat exchange with the surroundings, and prevents instabilities in the washing front.
