Werden nur aus dem Schwelgas Nebenprodukte gewonnen, so wird dasselbe nach dem Durchtritt durch die Nebenproduktenanlage B mittels des Rohrea bei h in den Generator zur Zersetzung der Reste von Teer und schweren Kohlenwasaerstonen zurückgeteitet (Fig. 1).
Anstatt das Gas wieder in denselben Generator zurückzuführen, kann es auch in einen K\"ei! tca Generator geleitet werden. Die Generatoren können natürlich beliebiger Bauart und mit festen oder beweglichen Rosten versehen sein.
Soll die Anlage zur Gewinnung von Ammoniumsulfat nach dem ,,direkten" Verfahren arbeiten, so muss das Gas bei seinem Eintritt in den Sättiger eine Temperatur von 80 bis 85 C. haben. Das Gas aus der ersten Zone ist tach seiner Reinigung kalt und muss deshalb erwärmt werden. Diese Erwärmung wird nun nach der Erfindung in einfachster Weise durch die Zusammenführung des kalten Gases mit dem heissen Gase der zweiten Zone erreicht ; Es wird durch diese Anordnung an Heizvorrichtungen und an Brennstoff gespart.
Eine diesem Zweck dienende Anlage ist durch Fig. 2 schematisch veranschaulicht.
Das aus der Destillationszone c kommende Schwelgas tritt durch das Rohr d in den Teerreiniger i, der in beliebiger Weise ausgeführt und auch aus mehreren Apparaten zusammen- gesetzt sein kann. Nach der erfolgten Reinigung wird das Gas bei k mit dem durch das Rohr f zugeleiteten heissen Gase der Vergasungszone e vereinigt und mit ihm gemeinsam in den Sättiger l geführt, worin sich Ammoniumsulfat bildet. Von dort aus wird das Gas zu beliebiger Verwendung
EMI2.1
Bei dem Generator nach Fig. 3 gelangt das aus det Zone c kommende Schwelgas durch pin Rohr m zum Kondensator o, wo es von Gaswasser, Ammoniak und Teer befreit wird, verlässt ihn durch ein Rohr p und strömt teils durch ein Rohr pl zum Feuer a zurück, das durch ein Rohr a1 Luft erhält. teils in ein Rohr r, das die aus der Zone e kommenden permanenten Gase abführt. Die gemischten Gase werden dann weiter auf Nebenprodukte verarbeitet.

1. Verfahren zur Gewinnung von Ammoniak und anderen Nebenprodukten aus bituminösen Brennstoffen. dadurch gekennzeichnet, dass die Verbrennung in Generatoren mit mehreren Fetterzonen vorgenommen wird und dass die Gase aus verschieden stark erhitzten Zonen getrennt abgeleitet werden.

If by-products are only obtained from the carbonization gas, after passing through the by-product system B, the same is returned to the generator at h by means of the Rohrea to decompose the residues of tar and heavy hydrocarbons (Fig. 1).
Instead of returning the gas to the same generator, it can also be fed into a K \ "ei! Tca generator. The generators can of course be of any design and have fixed or movable grates.
If the plant for the production of ammonium sulphate is to work according to the "direct" process, the gas at its entry into the saturator must have a temperature of 80 to 85 C. The gas from the first zone is cold after being cleaned and must therefore According to the invention, this heating is achieved in the simplest manner by combining the cold gas with the hot gases of the second zone; this arrangement saves heating devices and fuel.
A system serving this purpose is illustrated schematically by FIG.
The carbonization gas coming from the distillation zone c passes through the pipe d into the tar cleaner i, which can be designed in any way and also be composed of several apparatuses. After the cleaning has taken place, the gas is combined at k with the hot gases from the gasification zone e fed through the pipe f and fed with it into the saturator 1, in which ammonium sulfate is formed. From there, the gas can be used anywhere
EMI2.1
In the generator according to FIG. 3, the carbonization gas coming from the zone c passes through a pipe m to the condenser o, where it is freed from gas water, ammonia and tar, leaves it through a pipe p and partly flows through a pipe pl to the fire a back, which receives air through a pipe a1. partly into a pipe r, which discharges the permanent gases coming from zone e. The mixed gases are then further processed for by-products.
EMI2.2
1. Process for the recovery of ammonia and other by-products from bituminous fuels. characterized in that the combustion is carried out in generators with several fat zones and that the gases are diverted separately from zones that are heated to different degrees.
