Title: Process for the removal of sulphur compounds from gases
Inventor: BUISMAN CEES JAN NICO
IPC: C02F3/34
Filed: 1991-12-04
Abstract: PCT No. PCT/NL91/00250 Sec. 371 Date May 26, 1993 Sec. 102(e) Date May 26, 1993 PCT Filed Dec. 4, 1991 PCT Pub. No. WO92/10270 PCT Pub. Date Jun. 25, 1992.A process for the removal of sulphur compounds from a gaseous effluent, comprising the steps of: a) contacting the gaseous effluent with an aqueous solution wherein sulphur compounds are dissolved; b) adjusting the concentration of buffering compounds such as carbonate and/or bicarbonate and/or phosphate in the aqueous solution to a value between 20 and 2000 meq/l; c) subjecting the aqueous solution containing sulphide to sulphide-oxidizing bacteria in the presence of oxygen in a reactor wherein sulphide is oxidized to elemental sulphur; d) separating elemental sulphur from the aqueous solution; and e) recycling the aqueous solution to step a). This process is suitable for removing H2S from biogas, ventilation air etc. It can be used for removing SO2 from combustion gases by introducing the additional step, after step a) and before step c), of subjecting the aqueous solution containing the sulphur compounds to a reduction of the sulphur compounds to sulphide. H2S and SO2 removal is further enhanced by a residual sulphur content in the washing liquid of 1-50 g/l.

IPC: G01N33/58
Filed: 1981-07-29
Abstract: Erfindungsgemäß wird unter Anwendung eines immuno-immobilisierten Präzipitationsreagens (IIPR) ein neues, universell rationell anwendbares Verfahren zur Trennung des freien und antikörpergebundenen Liganden bei labelled-Ligand-Immunoassay-Systemen beschrieben. Dieses Verfahren vereinigt die Vorzüge der Doppelantikörpertechnik und die der Solid-Phase-Methoden, wobei gleichzeitig deren Nachteile umgangen werden. Die geringe unspezifische Bindung des markierten Liganden bietet eine wichtige Voraussetzung für empfindliche, präzise Assay-Systeme. Durch Anwendung des neuen Trennverfahrens sind die labelled-Ligand-Immunoassays sowohl in der Herstellung als komplette Kits als auch in der Durchführung selbst, zu standardisieren, wodurch eine wesentliche Kostensenkung z. B. der radioimmunologischen Bestimmungen möglich ist.
