Description

Beschreibung und Erläuterung zur Zusatz-Patentanmeldung 'Verfahren zur Auswaschung von SO2, insbesondere hinter Kraftwerksanlagen oder ähnlichen Rauchgas-entwickelnden Anlagen'
Zusatzanraeldung zur Patentanmeldung P 23 23 508.7Description and explanation of the additional patent application 'Process for leaching SO2, especially behind power plants or similar systems that generate flue gas'
Additional application for patent application P 23 23 508.7

In der Hauptanmeldung wird ein Verfahren zur Auswaschung von S02, HCl, Fluor, Staub und ähnlichen Rauchcrasbegleitern beschrieben, das dadurch gekennzeichnet ist, daß das Waschwasser im Kreislauf gefahren wird und mit ungelöschtem Kalk bei nicht genügend hohem Chlorionen-Anteil zusätzlich HCl zugeimpft wird.The main application describes a process for washing out S02, HCl, fluorine, dust and similar smokers described, which is characterized in that the washing water is circulated and with undeleted Lime is additionally inoculated with HCl if the chlorine ion content is not high enough.

Dieses Verfahren kann erfindungsgemäß wesentlich verbilligt werden, in dem man anstelle der Salzsäureimpfung z.B. Kalziumchlorid zusetzt·According to the invention, this method can be significantly cheaper by adding e.g. calcium chloride instead of hydrochloric acid

Dieses Kalziumchlorid^fällt z.B. als Nebenprodukt an, zwangs läufig bei der Kaustifizierung der Natronlauge.This calcium chloride occurs, for example, as a by-product, inevitably common in causticizing caustic soda.

Dieses Abfallprodukt ist im Gegensatz zu ungelöschtem Kalk im Bezug mit nur ca. 20 % Erstehungspreis gegenüber ungelöschtem Kalk zu bewerten.In contrast to quicklime, this waste product has a purchase price of only approx. 20% compared to unslaked lime Evaluate lime.

Es kann in absehbarer Zeit auch als Abfallprodukt vonIt may in the foreseeable future also be a waste product of

roßen chemischen Firmen bezogen werden, wo dieser Preis nochmals unterboten werden kann. r variables chemical companies are based, may be where this price n ochmals undercut.

um die SO2-Wäsche zu optimieren, können erfindungsgemäß anstelle der zugeiinpften HCl-Ionen beliebige Alkalichloride Anwendungen finden.in order to optimize the SO2 scrubbing, according to the invention instead of the injected HCl ions, any Find alkali chlorides applications.

Erfindungsgemäß wichtig ist aber eine grundsätzliehe Chlorimpfung neben der Zugabe von ungelöschtem Kalk für eine optimierte S02-Waschung.According to the invention, however, a fundamental one is important Chlorine inoculation in addition to the addition of unslaked lime for optimized SO2 washing.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, bei Rauchgaswäschen, die mit S02 angereichert gind, außer ungelöschtem Kalk Chlorionen zuzuimpfen in Form von verschiedensten chemischen Verbindungen, in der Art, wie sie sich preiswürdig anbieten.Of course, the invention is not limited to those shown and described in detail above Forms of training limited, but numerous changes are possible without, however, from the basic idea deviate, in the case of flue gas scrubbing that is enriched with S02, except for unslaked lime to inoculate chlorine ions in Form of various chemical compounds in the way that they are inexpensive.
