    Abstract: Production of pigmented resin powders by finely dispersing dispersions of pigments in solutions of polymeric materials in at least one organic solvent in water containing a protective colloid while supplying mixing energy, and removing the solvent. A preferred method is to introduce one or more jets of water containing protective colloid at the rate of 5 to 100 m/sec into animpulse exchange chamber together with the dispersion issuing in the immediate vicinity of the orifice(s), and to remove the solvent. The method avoids crosslinking and provides pigmented resin powders of consistently reproducible color which are suitable for conventional powdered-resin coating methods.

    Abstract: A gas mixture (obtained by thermal cracking of hydrocarbons followed by quenching of the cracked gas and freed from carbon dioxide and water) is separated into a gas mixture containing hydrogen, carbon monoxide and methane and another gas mixture containing ethylene, acetylene and higher hydrocarbons by (a) cooling the gas mixture which is at superatmospheric pressure in at least one condensation stage to a temperature which is above the solidification temperature of acetylene mixed with the other condensed constituents, (b) separating the condensate thus obtained and subdividing it in a rectifying column into a first mixture containing C2 hydrocarbons and a second mixture containing C3 and higher hydrocarbons, and (c) freeing the residual gas remaining from (a) from residual acetylene and ethylene in a scrubber by treatment with some of the mixture consisting of C3 and higher hydrocarbons from (b).

    Abstract: 1286983 Contacting gases with liquids; gas/ liquid catalytic reactions; controlling exothermic reactions BADISCHE ANILIN- & SODAFARIK AG 18 Sept 1969 [19 Sept 1968] 45983/69 Headings B1F B1R and B1X In an exothermic catalytic reaction involving a gaseous reactant and carried out in the presence of a liquid reaction medium containing a dissolved or suspended catalyst a portion of the liquid reaction medium is withdrawn during the reaction and recycled to the remaining liquid reaction medium through a nozzle at a speed of 5 to 100 metres per second at the point where the gaseous reactant is introduced below the surface of the liquid reaction medium, the recycled liquid reaction medium being introduced into an open-ended chamber located in the liquid reaction medium and extending in the direction of entry of the recycled liquid reaction medium and which has an inlet opening with a mean diameter of from 2 to 20 times the mean diameter of the nozzle and a length of 3 to 30 times its hydraulic diameter, and heat is withdrawn from the liquid reaction medium outside the open-ended chamber. In the apparatus shown in the drawing liquid reaction medium is withdrawn from vessel 4 (which may be jacketed) by a pump 6 passed through a cooler 11 and returned via line 7 and nozzle 1 at the upper end of an open-ended chamber 3. Gaseous reactant enters at 2 and further heat is withdrawn from the reaction by means of a cooling coil 12. The gaseous reactant may react with a second reactant which is dissolved in and/or suspended in the liquid reaction medium. The second reactant may also be gaseous. The gaseous reactant may be hydrogen and the catalyst a hydrogenating catalyst.

    Abstract: 1405264 Aerating liquids BADISCHE ANILIN- & SODA-FABRIK AG 13 Oct 1972 [14 Oct 1971] 47273/72 Divided out of 1303163 Heading B1C In a process for oxygenating a body of liquid e.g. waste liquid containing activated sludge, air is introduced into the body of liquid together with a submerged jet of the liquid partly by the inductive action of the jet and partly by a pump. The jet of liquid having a speed of from 5 to 100 metres per second and being directed into an open-ended confined mixing zone 3 of hydraulic diameter 2 to 20 times the diameter of the liquid nozzle 1 and of length 2 to 30 times its hydraulic diameter. Liquid from the vessel 4 is circulated by a pump 7 and fresh waste liquor may be introduced continuously by a line 8, treated liquor overflowing at 5 to settling tanks. The combined air/liquid jet nozzle 1 may be located horizontally, vertically or at any intermediate position.
