Filed: 1974-06-14
Abstract: 1469317 Plasma heated reaction vessel INSTITUT TEPLO-I MASSOOBMENA AKADEMII NAUK BELORUSSKOI SSR 14 June 1974 26409/74 Heading H5H Plasma torches 3 feed hot gas into the base of a reaction chamber 1 to heat particulate liquid or solid, or gas phase, material fed into the top of the chamber, the reaction products falling into a collection chamber 5 beneath the reaction chamber, hot waste gases escaping through outlets 6, and the torches being arranged at right angles to the vertical axis of the reaction chamber. By providing waste gas outlets beneath the plasma torches (Figs. 4, 5, 6) the plasmas from torches 3 can be split, part going up into the reaction chamber, part going with the reaction products into the collection chamber. Feed material may enter through a hollow electrode (25, Fig. 6, not shown) of a further plasma torch at the top of the reaction chamber for initial heating (e.g. for drying and driving off other volatile matter) of the charge material. Further torches (28, Fig. 7, not shown) may be arranged at right angles to the axis of the chamber at the top of the reaction chamber. When gas outlets are provided from the collection chamber, they may communicate with the collection chamber via a sleeve (22, Fig. 5, not shown) surrounding a further sleeve (21) through which material from the reaction chamber drops into the collection chamber. The spent gases heat the sleeve (21) to prevent solidification of material on the inside wall.

Title: Improvements in the production of regenerated cellulose products by the viscose process
IPC: D01F2/06
Filed: 1946-09-04
Abstract: In the production of regenerated cellulose products by the viscose process, the coagulated and at least partly regenerated but not desulphurized products are treated with a solution of a metaphosphate, tetraphosphate or polyphosphate or a corresponding free phosphoric acid, whereby impurities causing discolouration are removed.  Preferably, the product is treated while still wet from the coagulating bath.  The acidity of the solution should correspond to pH3 or lower (this is including acidity due to acid from the coagulating bath).  In the preferred method of carrying out the invention, the phosphate, especially an alkali metal hexametaphosphate, in amount 0.025 to 0.1 per cent based on the water is added to one or more portions of the wash water used for the removal of the acid coagulating bath.  The phosphate is of advantage added to the first wash water, but if desired it may be included in subsequent washes.  The temperature of the wash liquid is preferably between 50 DEG  and 60 DEG  C., though temperatures down to 30 DEG C. may be used.  Any commercially available alkali metal metaphosphate may be employed, such as Graham's salt, "Buromin," "Calgon" (both Registered Trade Marks), Sofos, Quadrafos and sodium tri-polyphosphate.  In an example, a freshly-spun unwashed cake of viscose yarn on a foraminated aluminium bobbin is placed in a washing unit equipped with evacuation apparatus.  After effecting the vacuum seal, the tub is filled with wash water at 60 DEG  C. to which 0.1 per cent sodium hexametaphosphate has been added, and washing continued for 50 minutes.  The tub is then drained and the yarn package washed with hot water and desulphurised &c.

Title: Improvements in the interaction of hydrocarbons with oxygen
IPC: C01B3/36
Filed: 1955-09-21
Abstract: Acetylene is produced by the reaction of hydrocarbons with oxygen in which the reactants are separately preheated, mixed and supplied to a reaction chamber, wherein upon the occurrence of a flame or a premature reaction within the mixing apparatus, an inert gas or vapour is supplied for a short time.  The inert gas which may be nitrogen, steam or carbon dioxide, is preferably automatically supplied to the oxygen current on the occurrence of a flame.  In an example, 1800 cu. metres of methane per hour and 1050 cu. metres of oxygen per hour are preheated and then heated to 600 DEG  C.  After mixing, the gases are reacted with flame formation to produce a gas containing 8.5 per cent of acetylene. If the mixture ignites in the mixing chamber, about 250 litres of nitrogen is injected into the oxygen supply in the course of about 2 seconds and the flame extinguished.  Specification 767,369 is referred to.ALSO:Hydrogen is produced by the reaction of hydrocarbons with oxygen in which the reactants are separately preheated, mixed and supplied to a reaction chamber, wherein upon the occurrence of a flame or a premature reaction within the mixing apparatus, an inert gas or vapour is supplied for a short time.  The inert gas which may be nitrogen, steam or carbon dioxide, is preferably automatically supplied to the oxygen current on the occurrence of a flame.  In an example, 250 cu. metres of coke oven gas (30 per cent methane) saturated with steam at 70 DEG  C. and 46 cu. metres of oxygen saturated with steam at 70 DEG C. are fed to preheaters per hour.  Then the gases pass at 600 DEG C. over a catalyst prepared by soaking magnesite with an aqueous solution of nickel nitrate to produce 400 cu. metres of synthesis gas containing 68 per cent of hydrogen.  If a premature reaction takes place, a thermocouple automatically operates a valve which injects steam with the oxygen feed and extinguishes the flame in less than 5 seconds.

IPC: B01D3/30
Filed: 1958-08-22
Abstract: <PICT:0887910/III/1> The centrifugal apparatus of Specification 598,531, (which comprises fixed and rotary plate E, B, respectively carrying rings or having corrugations so that the rings or corrugations on the fixed plate alternate with those on the rotary plate), is modified for use in fractional distillation by mounting it inside a boiling vessel F and providing it additionally with vanes A attached to the lower rotary plate B on the face opposite to that carrying the rings or corrugations C, and with an annular baffle J fitted in the vessel just below the vanes.  Preferably the distances between the rings or corrugations on the plates E, B are such that the area of plate enclosed between any two consecutive rings or corrugations is constant.  Both plates E and B may rotate if desired. In an example a mixture of n-heptane and toluene is separated by passing it through an inlet L into the boiling vessel F, introducing steam by inlet P into jacket O, passing the vapours from the mixture between the rings or corrugations C and D and through line K to a condenser and returning the condensate to the distillation apparatus by a line L, whence it flows centrifugally and countercurrent to the vapours to the periphery of the rotary plate B to be returned by piplines H to the mixture in vessel F. When the proportion of n-heptane in the liquid returning to the top of the apparatus by line L no longer rises, liquid rich in n-heptane is removed from the line L and spent liquor rich in toluene is obtained from outlet M.
