Description

Verfahren zur Reinigung von Rohgasen, wie z. B. Kokereigas Es ist bereits bekannt, zur Reinigung von Rohgasen, wie z. B. Kokereigas, die zur Herstellung von Stickstoffwasserstoffgemischen dienen sollen, sich einer Alkalicarbonatlösung zu bedienen, wodurch in der Hauptsache die Kohlensäure . herausgewaschen werden soll. Man weiß ferner, daß ungesättigte Kohlenwasserstoffe. wie Acetylen, durch Waschen mit Acetonlösung beseitigt werden. Der Erfindung liegt nun die Erkenntnis zugrunde, daß man mit einem einmaligen Waschen dann auskommen kann, wenn der Alkalicarbonatlösung Aceton zugesetzt wird. Man gelangt auf diese Weise in einem Arbeitsgang zu einer Befreiung des Gases von allen unerwünschten fremden Stoffen.Process for the purification of raw gases, such as B. Coke oven gas It is already known for the purification of raw gases such. B. coke oven gas used for production of nitrogen-hydrogen mixtures are to be used, an alkali carbonate solution to use, whereby mainly the carbonic acid. be washed out target. It is also known that unsaturated hydrocarbons. like acetylene, through Washing with acetone solution can be eliminated. The invention now lies in the knowledge based on the fact that you can get by with a single wash if the alkali carbonate solution Acetone is added. In this way one arrives at one in one operation Removal of all undesirable foreign substances from the gas.

Im allgemeinen wird man das Verfahren bei gewöhnlicher Temperatur und gewöhnlichem Druck ausführen, doch ist man an die Innehaltung dieser Bedingungen nicht gebunden.In general, the procedure is carried out at ordinary temperature and carry out ordinary pressure, yet one is about to observe these conditions not bound.

Es war nicht vorauszusetzen, daß eine gleichzeitige Entfernung von Kohlendioxyd und ungesättigten Kohlenwasserstoffen durch die vorgeschlagene Maßnahme bewirkt werden könnte, da keineswegs feststand, wie weit die Alkalicarbonatlösung die Absorptionswirkung desAcetons in ein und derselben Lösung beeinflussen würde. Dadurch, daß beide Vorgänge aber zu einem einzigen zusammengefaßt werden konnten, ist der technische Prozeß nicht nur einfacher, sondern, wie sich herausgestellt hat, auch noch viel wirksamer gestaltet.It was not to be assumed that a simultaneous removal of Carbon dioxide and unsaturated hydrocarbons by the proposed measure could be effected, since it was by no means certain how far the alkali carbonate solution would affect the absorption effect of the acetone in one and the same solution. Because both processes could be combined into a single one, the technical process is not only simpler, but as it turns out has also made it much more effective.

PATENTANSPRUCH: Verfahren zur Reinigung von Rohgasen, wie z. B. Kokereigas, aus denen unter Anwendung des an sich bekannten Druckverflüssigungsverfahrens Wasserstoff bzw. Stickstoffwasserstoffgemische hergestellt werden sollen, von Kohlendioxyd und von den ungesättigten Kohlenwasserstoffen in einem Arbeitsbang durch Waschen mit einer Lösung von Alkalica.rbonat, dadurch gekennzeichnet, daß der zur Waschung benutzten Alkalicarbonatlösung Aceton zugesetzt ist. PATENT CLAIM: Process for the purification of raw gases such. B. coke oven gas, from which hydrogen or nitrogen nitrogen mixtures are to be produced using the known pressure liquefaction process, of carbon dioxide and of the unsaturated hydrocarbons in a workbang by washing with a solution of Alkalica.rbonat, characterized in that the alkali carbonate solution used for washing Acetone is added.
