Bisher erfolgt die Nutzbarmachung des in den Kokereien und Gasanstalten sich ergebenden Gaswassers nur in der Richtung, daß das Ammoniak abdestilliert und an Schwefelsäure gebunden wird. Da im Gaswasser das Ammoniak zum großen Teil als Ammoniumcarbonat vorhanden ist, so enthalten die bei der Bindung des Ammoniaks bzw. bei der Darstellung von Ammoniumsulfat aus dem SättigungskastenSo far the utilization of the resulting in the coking plants and gas works has been carried out Gas water only in the direction that the ammonia is distilled off and sulfuric acid is bound. Since the ammonia in the gas water is largely in the form of ammonium carbonate is present, they are contained in the binding of the ammonia or in the representation of ammonium sulfate from the saturation box
ίο entweichenden Gase hauptsächlich Kohlensäure (etwa 95 Prozent), neben dieser aber auch noch Wasserdampf, Schwefelwasserstoff, Cyanverbindungen, Spuren von Schwefeldioxyd und von Kohlenwasserstoffen. Es handelt sich nun darum, das in den genannten Gasen enthaltene Kohlendioxyd von den Beimengungen zu befreien, was nach dem den Erfindungsgegenstand bildenden Verfahren auf Grund einer Kombination bekannter Reaktionen zur Bindung des Schwefelwasserstoffs, und der Cyanverbindungen sowie zur Oxydation der Kohlenwasserstoffe geschieht.ίο escaping gases mainly carbonic acid (about 95 percent), but in addition to this also water vapor, hydrogen sulfide, cyano compounds, Traces of sulfur dioxide and hydrocarbons. It is now a matter of what is contained in the gases mentioned To free carbon dioxide from the admixtures, what after the subject of the invention forming processes based on a combination of known reactions for binding the hydrogen sulfide, and the cyano compounds as well as for the oxidation of the hydrocarbons happens.
Es ist wohl bereits vorgeschlagen worden, die bei der Darstellung von Ammoniumsulfat entweichenden Gase zwecks Nutzbarmachung der Cyanverbindungen bzw. zwecks Gewinnung von Ferrocyanalkalien durch mit Alkali versetzte Eisensalzlösungen zu leiten. Durch eine derartige alleinstehende Maßnahme wird aber der gemäß vorliegender Erfindung angestrebte Zweck — die Gewinnung reiner Kohlensäure — keineswegs erreicht. Vielmehr erscheint hierzu eine dem vorliegendenVerfahren zugrunde liegende Kombination von an sich bekannten Reaktionen erforderlich, wobei dieses Verfahren selbst im wesentlichen darin besteht, daß die nach dem Binden des Ammoniaks an Schwefelsäure verbleibenden Gase zunächst zur Wegschaffung der Cyanverbindungen und des Schwefelwasserstoffs mit Metallsalze enthaltenden Abfallaugen in Berührung gebracht und dann zwecks Zersetzung der Kohlenwasserstoffe über erhitztes Kupferoxyd geleitet werden.It has probably already been suggested in the preparation of ammonium sulfate escaping gases for the purpose of utilizing the cyano compounds or for the purpose of extraction of ferrocyanic alkalis through iron salt solutions mixed with alkali. By a such a stand-alone measure, however, is the one aimed at in accordance with the present invention Purpose - the production of pure carbon dioxide - by no means achieved. Rather appears for this purpose a combination of known methods on which the present method is based Reactions required, this process itself essentially consists in that the After the ammonia has bound to sulfuric acid, the remaining gases are initially disposed of of the cyano compounds and hydrogen sulfide brought into contact with waste eyes containing metal salts and then passed over heated copper oxide to decompose the hydrocarbons.
Behufs praktischer Durchführung des in Rede stehenden Verfahrens wird das zu reinigende Gas zunächst mit Laugen zusammengebracht, die sich z. B. bei der Extraktion von Metallen, wie etwa bei der Gewinnung von Kupfer aus Kiesabbränden, bei der Entzinnung von Weißblechabfällen, ferner beim Beizen von zu emaillierenden Eisenwaren usw. ergeben. Alle diese Laugen enthalten wesentlich Metallchloride und können entweder ohne weiteres oder nach Zusatz von alkalischen Stoffen, z. B. Soda, verwendet werden. Durch die Metallsalze der Laugen werden die Cyanverbindungen und der Schwefelwasserstoff, zurückgehalten. Spuren von Kohlenwasserstoffen, die in den Gasen enthalten sind, werden dadurch, daß man das Gas mit glühendem Kupferoxyd in Berührung bringt, entfernt.For the purpose of practicing the procedure in question, that is to be cleaned Gas initially brought together with alkalis, which z. B. in the extraction of metals, such as in mining of copper from gravel burns, in the detinning of tinplate waste, also in Pickling of iron goods to be enamelled, etc. result. All of these alkalis contain essentials Metal chlorides and can either readily or after the addition of alkaline Substances, e.g. B. soda can be used. The cyan compounds are formed by the metal salts of the alkalis and the hydrogen sulfide, retained. Traces of hydrocarbons, those contained in the gases are removed by bringing the gas into contact with glowing copper oxide.
Man erhält auf diese Weise reines, geruchloses Kohlendioxyd, das nach vollständigem Trocknen komprimiert und in gebräuchlicher Weise in Stahlflaschen vorrätig gehalten werden kann.In this way, pure, odorless carbon dioxide is obtained, which after complete Dry compressed and kept in stock in steel bottles in the usual way can.
Bisher wurden die zum überwiegenden Teil aus Kohlensäure bestehenden, von AmmoniakSo far, the predominantly carbonic acid, ammonia
