Description

Verfahren zur Gewinnung von Chlorammonium aus kochsalzhaltigen Lösungen. In dem Hauptpatent 376793 ist ein Verfahren zur Gewinnung von Chlorammonium aus den Mutterlaugen der Ammoniaksodafabrikation beschrieben, welches darin besteht, daß man die mit Kochsalz gesättigten Laugen durch Eintragen bemessener Mengen von solchen festen oder flüssigen Stoffen, die bei gewöhnlicher Temperatur und gewöhnlichem Druck gasförmig sind, abkühlt, wobei sich das Chlorammonium in technisch reiner Form abscheidet.Process for the production of chlorammonium from solutions containing sodium chloride. In the main patent 376793 a process for the production of chlorammonium from the mother liquors of the ammonia soda production is described, which consists in that the lyes saturated with common salt by introducing measured amounts of such solid or liquid substances, which are gaseous at usual temperature and pressure, cools down, the chlorammonium separating out in technically pure form.

Es hat sich nun gezeigt, daß man sehr vorteilhaft arbeitet, indem man namentlich die Kälteleistung der Kühlmittel viel besser ausnützt, wenn man in der Weise verfährt, daß man die flüssigen, unter Druck stehenden Kühlmittel so in die zu kühlende Flüssigkeit einführt, daß sie innerhalb dieser selbst verdampfen müssen.It has now been shown that one works very advantageously by In particular, the cooling capacity of the coolant is used much better if one is in the way of proceeding that one the liquid, pressurized coolant so in introduces the liquid to be cooled that they evaporate within this itself have to.

Man läßt z. B. flüssige Kohlensäure durch eine Rohrleitung, die in der zu kühlenden Flüssigkeit endigt und an dieser Endigung eine Verengung aufweist, in die zu kühlende Flüssigkeit eintreten. Es findet eine dauernde Verdampfung der Kohlensäure statt, während die Flüssigkeit in lebhafteste Bewegung gerät, so daß sich eine weitere Rührung vollkommen erübrigt. Die erzielte Kälteleistung entspricht nahezu der theoretisch möglichen.One lets z. B. liquid carbonic acid through a pipe that runs in the liquid to be cooled ends and has a constriction at this end, enter the liquid to be cooled. There is a permanent evaporation of the Carbonic acid takes place while the liquid is in the most lively movement, so that further agitation is completely unnecessary. The achieved cooling capacity corresponds to almost the theoretically possible.
