Verfahren zur Abscheidung des Teers aus heissen Destillationsgasen.
Den Teer aus heissen Destillationsgasen abzuscheiden behufs Gewinnung des Ammoniaks durch direkte Fällung in einem Säurebad sind verschiedene Verfahren bekannt geworden.
Am wirksamsten haben sich diejenigen erwiesen. welche sich des Teeres als Waschmittel bedienen, weil der Teer das beste Lösungsmittel für Teerdämpfe ist. Es wird auch teeriges Gaswasser mit Erfolg benutzt, denn das Gaswasser wird bei Benutzung sofort tecrhaltig. Unter den
EMI1.1
nicht überschreiten darf, dass aber auch bei dieser Temperatur des Waschmittels das Gas heiss genug bleibt, um sämtliches Ammoniak im Gase zur direkten Fällung zu bringen. Das Waschmittel in seiner Temperatur niedriger zu halten, ist selbstverständlich auch nicht günstig, aber

Diese Aufgabe, so wichtig sie ist. kann verschiedene Lösungen finden. Z. B. die einfache, die Waschung (mit Teer) bei der Gastemperatur einzusetzen, welche eine Überschreitung der T Temperatur des Waschmittels von 80"unmöglich macht, doch kann sie je nach dem Gehalt des

Process for separating tar from hot distillation gases.
Various processes have become known to separate the tar from hot distillation gases in order to obtain the ammonia by direct precipitation in an acid bath.
Those have proven to be the most effective. who use tar as a detergent because tar is the best solvent for tar fumes. Tarry gas water is also used successfully, because the gas water immediately becomes tecrhaltig when used. Under the
EMI1.1
must not exceed that, even at this temperature of the detergent, the gas remains hot enough to cause all of the ammonia in the gas to precipitate directly. Keeping the detergent at a lower temperature is of course not cheap either, but
EMI1.2
This task, important as it is. can find different solutions. For example, the simple one of using the washing (with tar) at the gas temperature, which makes it impossible to exceed the T temperature of the washing agent by 80 ", but depending on the content of the
Gases in steam cause disruptions in the direct precipitation of ammonia.
You can also use a sufficient supply of detergent, which allows cooling. secure the temperature limit; also by adding gas water.
