Patent number: 7931721Abstract: The invention relates to a droplet separating system for gas washers and similar, comprising at least one droplet separating layer and a rectifier layer which is arranged upstream in the direction of the flow of gas. The rectifier elements of the rectifier layer are arranged in the form of a V or an upturned V having opposite inclinations to the droplet separating profiles of the droplet separating layer. As a result, the rectifier layer is contaminated in a slow manner due to the increased performance of the droplet separating system.Type: GrantFiled: March 9, 2007Date of Patent: April 26, 2011Assignee: Munters Euroform GmbHInventors: Helmut Kanka, Hubert Wolf, Peter Wandres

Patent number: 5749930Abstract: Described is a mist collector arrangement for gas washers etc. having in gas flow direction a downstream and an upstream mist collector layer. The profiles of the successively arranged rows of the downstream and upstream mist collector layers are positioned oppositely with respect to one another in gas flow direction. In this manner an improved cleaning effect is obtained when periodically rinsing the mist collectors.Type: GrantFiled: June 5, 1996Date of Patent: May 12, 1998Assignee: Munters Euroform GMBHInventors: Hubert Wolf, Siegfried Bulang, Olaf Cohrs

Patent number: 5569386Abstract: A method for controlling the detoxification of aqueous solutions containing cyanides and/or cyano complexes, in particular zinc cyano complexes, with the use of a source for formaldehyde for glycolnitrile formation and a source for hydrogen peroxide for perhydrolysis of the glycolnitrile is disclosed. During the addition of the source for formaldehyde at a pH value in the range from 8.5 to 12 the pH value is kept constant by addition of an acid. The addition of the source for formaldehyde is discontinued if the pH value no longer increases.Type: GrantFiled: December 5, 1994Date of Patent: October 29, 1996Assignee: Degussa AktiengesellschaftInventor: Hubert Wolf

Patent number: 5389127Abstract: A method for cleaning a drop separator includes the steps of mounting a plurality of parallel blades along a gas channel, spraying the blades with cleaning jets of wash water pulsed from a plurality of flat jet nozzles, and displacing the plurality of the nozzles perpendicular to a direction of gas flow while spraying the blades.Type: GrantFiled: May 3, 1993Date of Patent: February 14, 1995Inventors: Dieter Wurz, Stefan Hartig, Hubert Wolf

Patent number: 5306431Abstract: Reduction of the nitrite content of aqueous solutions by treatment with hydrogen peroxide in the acidic pH range can be controlled by measurement of the redox potential. Contrary to the teaching of the prior art, addition of the hydrogen peroxide in the process according to the invention is terminated not at the highest redox potential, but only after lowering of the potential to a value of 650.+-.10 mV. In this way, nitrite contents below 1 mg/l can be obtained even when the solutions additionally contain fluctuating amounts of various compounds oxidizable by H.sub.2 O.sub.2.Type: GrantFiled: August 7, 1992Date of Patent: April 26, 1994Assignee: Degussa AktiengesselschaftInventors: Joachim Fischer, Hubert Wolf, Klaus Stuetzel, Friedhelm Brandner, Manfred Diehl

Patent number: 5204008Abstract: A process is disclosed for the detoxication of aqueous solutions which contain cyanohydrins, in particular glycol nitrile, and/or nitriles and in addition contain decomposition catalyst for peroxide compounds, in particular manganese compounds, by perhydrolysis of the cyano compounds at temperatures of from 5.degree. to 80.degree. C. and pH values of from 8 to 12 by means of one or more peroxide compounds which are alkali metal percarbonates and perborates of alkali metals and alkaline earth metals and alkaline earth metal peroxides. The peroxide compounds are added as such to the solution to be detoxified or formed in situ in the solution to be detoxified. Sodium percarbonate is preferably used.Type: GrantFiled: March 26, 1992Date of Patent: April 20, 1993Assignee: Degussa AktiengesellschaftInventors: Manfred Diehl, Joachim Fischer, Hubert Wolf

Patent number: 5200161Abstract: A process is disclosed for the separation of hydrogen cyanide from gases and waste gases by a throughflow or circulation scrubbing, in which formaldehyde is added at a controlled rate to the aqueous scrubbing liquid to form glycol nitrile. This addition is controlled by measuring the HCN tension in a measuring stream which has been branched off and which is first treated with hydrogen peroxide so that free H.sub.2 O.sub.2 is still detectable after 1 to 100 seconds and the pH is adjusted to a constant value before measurement of the HCN tension is carried out. The process prevents overdosing with formaldehyde which could not always be prevented in previously known processes in which the addition of formaldehyde was regulated by measuring the cyanide specific redox potential.Type: GrantFiled: May 6, 1992Date of Patent: April 6, 1993Assignee: Degussa AktiengesellschaftInventors: Joachim Fischer, Hubert Wolf, Manfred Diehl

Patent number: 5068038Abstract: The content of halo-organic pollutants in water is lowered to residual AOX values below 1 mg/l, preferably below 0.1 mg/l by adjusting the Fe.sup.2+ comtent of the water to 20 to 1000 mg/l, adding a precipitated or pyrogenic silicic acid, converting 20 to 1000 mg of the Fe.sup.2+ into Fe.sup.3+ by adding in an oxidation agent, preferably hydrogen peroxide, and separating the iron (III) hydroxy complexes formed and the silicic acid, which contain the halo-organic pollutants in an adsorbed state, at pH 5-10. The method can be controlled in a simple manner as regards the addition of Fe.sup.2+ and oxidation agent via the Fe.sup.2+ /Fe.sup.3+ redox potential.Type: GrantFiled: September 18, 1990Date of Patent: November 26, 1991Assignee: Degussa AktiengesellschaftInventors: Joachim Fischer, Hubert Wolf

Patent number: 4871681Abstract: According to the invention, cyanide concentrations of approximately 0.001 to 5 mg cyanide/1 are colorimetrically determined in a continuous manner by means of the known cyanidepicric acid color reaction. The solution containing free cyanide and/or cyanide releasable from cyanocomplexes is converted in a system enclosed in a gas-tight manner in the presence of chelate complexing agents, picric acid and alkaline buffer systems in 1-60 minutes at 50.degree.-120.degree. C. to the color complex and the absorbency is measured spectrophotometrically. The method avoids the extraction step which was previously necessary under 0.2 mg CN/1, avoids errors due to HCN gas evolution losses, is easy to manage, not prone to trouble and suitable for the continuous monitoring of waste-water streams or for controlling cyanide detoxification methods.Type: GrantFiled: November 30, 1987Date of Patent: October 3, 1989Assignee: Degussa AktiengesellschaftInventors: Edgar Bilger, Hubert Wolf
