Abstract: A method for processing a tar which is formed during the oxidation of an alkyl-benzene compound and which contains substituted or unsubstituted benzyl benzoate, which method comprises the steps of subjecting the tar to either hydrolysis or ammonolysis and then extracting the reaction mixture which is formed from the hydrolysis or ammonolysis. The extracting agent is organic and causes the reaction mixture to separate into liquid phases. The liquid phases are then separated for further processing.

Abstract: Process for concentrating a urea solution passing as a film along the inside of the tubes (2) of a vertical tube bundle the heat required being substantially generated by condensation of a gas mixture in a area provided around the bundle of tubes, the gas mixture being supplied to the area near one end of the tube bundle (2) and the urea solution to the other end of the tube bundle (2), and being passed substantially upwards through the heating area and it is ensured that the gas mixtureor condensate cannot flow back. Installation for carrying out the process wherein the heating area is divided into compartment by means of horizontal baffles (3) allowing an upwardly directed flow of the gas mixture and the condensate.

Abstract: A process for stabilizing conventional particulate thermoplastic organic polymers by admixing conventional stabilizers for the polymers is disclosed, wherein the resulting polymer-stabilizing mixture is homogeneous and exhibits good polymer stability. The stabilizer has a melting point at least 1 DEG C less than the temperature at which the polymer agglomerates and/or sinters and/or decomposes. The stabilizer is in the non-liquid state and preferably has a viscosity of at least 50 poise, measured under the conditions at which the stabilizer is added to the polymer. The polymer is heated to a temperature above the melting point of the stabilizer, and lower than the agglomeration and/or decomposition and/or sintering temperature of the polymer. The stabilizer is admixed with the polymer while the polymer is maintained at about the aforesaid temperature, and while the stabilizer is at a temperature at least about 1 DEG C lower than the stabilizer melting point temperature. The mixing is preferably at a shear rate no greater than 1000 sec 1.

Abstract: Procedure for spraying a liquid by means of a gas or a mixture of gases in a two-phase sprayer consisting of a tube for the liquid with an outlet hole perpendicular to the direction of circulation and around this tube a coaxial tube for supplying the gas and which extends beyond the end of the tube for liquid and in which the gas stream surrounds and atomizes the outgoing liquid characterized in that the liquid is supplied with an exit velocity between 10 and 200 cm/second and the gas is supplied as a non-turbulent or barely turbulent current with unchanged or increasing velocity so that the gas stream is passed through a conicorode channel to the outgoing liquid stream while the angle between the directions of the gas stream and the liquid stream it is between 70º and 90º.

Abstract: The present invention relates to a process for separating waste material such as domestic refuse that has already been pretreated in order to eliminate the larger part of the paper, plastic film, food remnants and ferromagnetic materials and the particle size of which has been reduced to less than 70 mm through grinding. The waste material contains both glass and aluminium, in addition to other components. The ground waste material is separated by specific gravity in three hydrocyclones or hydrocyclone-batteries connected in series. In the first hydrocyclone, in which water is used as the separating medium, the lightest materials are separated. In the second hydrocyclone, a final heavy fraction is separated. In the third hydrocyclone, the intermediate fraction obtained in the second hydrocyclone is separated into a final fraction containing practically all the glass and a final fraction containing practically all the aluminium. In the second and third hydrocyclones a heavy suspension, of the same composition in both cyclones, is used as the separating medium.

Abstract: The invention relates to a process for the production of an object from a granular ABS polymer composition, said composition comprising a mixture of I 10-98 parts by weight of one or more graft copolymers obtained by polymerizing a mixture of one or more unsaturated nitriles and one or more vinylaromatic compounds in the presence of a rubber. II 2-90 parts by weight of a copolymer of one or more unsaturated nitriles and one or more vinylaromatic compounds, and III 0-20 parts by weight of one or more additives, wherein the polymer composition is melted, homogenized, and extruded or injection molded into an object. To improve the flow properties of the mixture introduced into the processing equipment and the throughput of this equipment the invention is characterized in that the ratio between the average particle size (by weight) of the copolymer II to the average particle size (by weight) of the graft copolymer I exceeds 1.5.
