Description
Herstellung von Alkalinitrat und Ammoniumchlorid aus Alkalichlorid Das Hauptpatent 558 151 schützt die Herstellung von Alkalinitrat und Salzsäure aus Alkalichlorid durch folgende im einzelnen bekannte Maßnahmen: a) Alkalichlorid wird nach Art des Ammoniak-Soda-Prozesses zu Alkalibicarbonat oder -carbonat umgesetzt; b) das Alkalibicarbonat oder -carbonat aus a wird in Mischung mit Kohlenstoff durch Einwirkung von Stickstoff in Alkalicyanid übergeführt; c) das Alkalicyanid aus b wird durch Behandlung mit Wasserdampf in Alkalicarbonat und Ammoniak gespalten; d) die Behandlung der Reaktionsmasse gemäß b und c wird gegebenenfalls zur Gewinnung weiterer Ammoniakmengen wiederholt; e) das Ammoniak aus c und d wird zu Stickoxyden, vorzugsweise zu Stickstoffdioxyd, oxydiert; f) weiteres Alkalichlorid wird mittels der Stickoxyde aus e in Alkalinitrat und Salzsäure umgesetzt; g) gegebenenfalls wird das Stickstoffdioxyd in Salpetersäure übergeführt und diese mit Alkalichlorid zur Reaktion gebracht.Production of alkali nitrate and ammonium chloride from alkali chloride The main patent 558 151 protects the production of alkali nitrate and hydrochloric acid Alkali chloride by the following individually known measures: a) Alkali chloride is converted to alkali bicarbonate or carbonate in the manner of the ammonia-soda process; b) the alkali bicarbonate or carbonate from a is mixed with carbon through Exposure to nitrogen converted into alkali metal cyanide; c) the alkali metal cyanide from b is split into alkali carbonate and ammonia by treatment with water vapor; d) the treatment of the reaction mass according to b and c is optionally used for recovery further amounts of ammonia repeatedly; e) the ammonia from c and d becomes nitrogen oxides, preferably oxidized to nitrogen dioxide; f) further alkali chloride is by means of the nitrogen oxides from e are converted into alkali metal nitrate and hydrochloric acid; g) if applicable the nitrogen dioxide is converted into nitric acid and this with alkali chloride brought to reaction.
Es wird also aus dem wohlfeilen Ausgangsmaterial Alkalichlorid durch zwei sinnvoll verbundene Prozesse das Alkalichlorid in wertvolle Salzsäure und wertvolles Alkalinitrat umgewandelt.The inexpensive starting material thus becomes alkali metal chloride two sensibly connected processes the alkali chloride into valuable hydrochloric acid and valuable Converted to alkali nitrate.
Es wurde nun gefunden, daß dieser technische Fortschritt noch weiter verbessert werden kann durch eine Abänderung des Verfahrens nach dem Hauptpatent, derart, daß nur ein Teil des in Stufe c erhaltenen Ammoniaks nach e zu Stickoxyden, der andere Teil hingegen mit der Salzsäure aus f zu Ammoniumchlorid -umgesetzt wird, wobei vorzugsweise ein solcher Teil des Ammoniaks aus c gemäß Stufe e zu Stickoxyden umgesetzt wird, daß die aus Stufe f -herstammende Salzsäure hinreicht, um den restlichen Teil des Ammoniaks aus c zu Arnmoniumchlorid zu binden.It has now been found that this technical advance still continues can be improved by changing the process according to the main patent, in such a way that only part of the ammonia obtained in step c becomes nitrogen oxides after e, the other part, however, is reacted with the hydrochloric acid from f to form ammonium chloride, wherein preferably such a part of the ammonia from c according to step e to nitrogen oxides is implemented so that the hydrochloric acid originating from stage f is sufficient to remove the remaining Part of the ammonia from c to bind to ammonium chloride.
Es wird also gemäß dem zusätzlichen Verfahren der Alkalibestandteil des Alkalichlorids zu Alkalinitrat und der Chlorbestandteil zu Ammoniumchlorid umgesetzt.That is, it becomes the alkali component according to the additional process of the alkali chloride converted to alkali nitrate and the chlorine component to ammonium chloride.
Durch einen völlig einheitlichen Verfahrensverlauf unter Verwendung von ausschließlich Alkalichlorid als Rohstoff neben den selbstverständlichen und nicht im eigentlichen Sinne als Rohstoffe zu bezeichnenden Stoffen Kohle, Stickstoff und Wasser werden also zwei wertvolle und begehrte Düngemittel hergestellt. Die Erzeugung des gebundenen Stickstoffs (Ammoniakstickstoff und Nitratstickstoff) vollzieht sich dabei in vorteilhaftester Ausnutzung des gleichen Ausgangsstoffes gemäß dem parallel geschalteten Kreislaufverfahren wiederholter Cyanisierung und Verseifung.By using a completely uniform process flow of exclusively alkali chloride as a raw material in addition to the obvious and Substances that cannot be designated as raw materials in the true sense of the word are coal, nitrogen and water, two valuable and sought-after fertilizers are produced. the Generation of bound nitrogen (ammonia nitrogen and nitrate nitrogen) takes place in the most advantageous use of the same starting material according to the parallel cycle process of repeated cyanization and Saponification.
