Title: Carbyl sulphate continuous production - by reacting ethylene with sulphur trioxide
Inventor: IRNICH RUDOLF DR
IPC: C07D327/10
Filed: 1975-03-06
Abstract: In the continuous prodn. of carbyl sulphate, ethylene and SO2 in a molar ratio of 1:2 to 1:2.4 are passed at 110-150 degrees C as a uniform stream or in countercurrent through at least one tube or a bundle of parallel tubes, the tube(s) being vertical or inclined at an angle of up to 45 degrees and the ratio of tube length to tube dia. being 600:1 to 200:1, and the resulting carbyl sulphate is withdrawn from the lower end of the reactor system with exclusion of moisture. Carbyl sulphate is an important inter. for e.g. ethionic acid and ethenesulphonic acid, as well as their esters and amine reaction products, e.g. taurine or N-methyltaurine, which in turn are important intermediates for copolymers, stabilisers, detergents, textile aids, emulsifiers, pharmaceuticals, etc. Partic. important is the conversion of carbyl sulphate into vinylsulphonic acid, alkali salts of which as important additives for galvanic baths. The process gives pure carbyl sulphate in good yields without the use of inert solvents. The explosion risk associated with a process in which SO3 diluted with an inert gas is reacted with ethylene is a cyclone is avoided.

Title: Borehole drilling technique for carboniferous strata - for subsequent underground gasification using e.g. oxygen enriched air
Inventor: LOKSCHIN JEFIM L
IPC: E21B49/00
Filed: 1975-04-10
Abstract: The borehole is drilled until it just reaches the roof of the deposit, and drilling is stopped after penetrating into the upper part of the stratum; the depths of the roof and floor of the stratum are then determined more esp. by core sampling using gamma radiation. Drilling is resumed to a depth allowing a rock pillar to remain, thus permitting mutually adjacent boreholes to be interconnected by a fluid passing through the mass of the stratum. The column of liner tubes is installed in the borehole, and the rock pillar left behind is then drilled out from the shoe of the liner tubes to the floor of the stratum, pref. using a gaseous medium or water. Method avoids the need for drill bits of various dia. and the need for the repeated raising and lowering of the drilling pipe string to change the drill tool. It also avoids the need to drill below the floor of the stratum. Boreholes of dia. 250-400mm or more can be drilled to depths of 300-400m or more.

Title: Salt removal from oil emulsion effluents - by centrifugal sepn. and evapn. to concentrate breaking chemicals
Inventor: FREUND HANS
IPC: C02F1/04
Filed: 1975-10-10
Abstract: The salts contained in the effluents from chemical dissociation plants for spent oil-in-water emulsions have to be removed before the wastes can be discharged into the drainage system. The oil phase, fluids of a greater specific gravity than water, and solids are removed in a centrifugal separator before the salts are removed by evaporation. The condensate need not be passed through a complex treatment to remove oil or solvent particles entrained by the vapours. Possible incrustation of the heat exchanger surfaces, caused by any oil content in the effluent, is eliminated. Any process, including flocculation, can be applied before evaporation, to achieve optimum results.
