` ,'Be'it known that I, 'FnnNz Wou?, a citi- :zen-.of Germany, and resident of Bochum, German ,L have invented oertain-` new and `'usefulIiiiproveinents iny Processes of Mak-V l'ing Ammoniun -Sulfate and Sulite, of which the following' is a specification'.
Eort's have been made to utilize the ad- -mixture of sulfurcontained in the v.coal in vstorm of sulfuric acid during the distillin manufacture of sulfate of ammoniumy pos' 'sible vineonnect-ion with the ammonia also .contained in the4 coal. This yis accomplished by. passing the gases of distillation of the l fecal, through gas-washers charged 4with oxid ofliron and .utilizing thel sulfur which klis won *thereby inthe purifying-mass, forv the manufacture of sulfuric acid in the caltuning-furnaces of the sulfuric acid. 'facto-` ri'es. The sulfuric acid-is-thenemployed in a subsequent process forj-the 4saturation -of ammonia gases for producing sulfate' of ammonium.v Recently 1t has also been provposed l-to expose these gases, which contain the sulfur in form of sulfureted hydrogen to an oxidation by the aid of aconta'ct-process with the-ammonia likewise contained in the gases. The first-named process has the disl other process is'not ,of the great danger incurred bythe neces- 40- in the p59. .g
advantage that `the gas 'purifying-mass must be yrepeatedly renewed and that the subsecomplicated.,calcining-process of this S5.
mass must be' carriedout -in sulfuric acid factories, thus requiring'an additional plant and -(.lomparatively expensive labor. The racticable on account sity of' admitting air tothe explosive. gases for oxidizing the sulfur, so that in view of.

4 Tlquwhwnjt my binations contained in the'gases emanating from the coking chambers ofthe coke oven oxid is formed. The ammonlacal `liquor tion formed b containing su fur-dioxid, thereby forming a solution of ammonium sulfate and ammonium sulfite, while the considerable heat still contained in these burned gases may be utilized for concentratin said solution.l vIt is obvious that in lieu ofgbringing said vburned gases inncontact with drizzling ammonia-cal liquor, they nia-y be brought in contact'with the gases of distillation produced in an ammonia distilling column, thereby obtaining the same result. After the reaction between the burned gases and the ammoniacal liqnor or vapor has taken place, the residual gasesmay be passed. through water sprays in order to completely precipitate the ammonia which may have lbeen occasionally carried along. This new treatment of thewaste-gases of cokeeovens with ampreviously obtained is then caused to driz A zle through the rising products of combusheating the coke oven and vso.
monia combinations can becarriedinto effeet in accordance with the construction of a coke-oven `at the point where the utilization otf'the heat of the ases permits be reduced tooA much by this treatment of the waste-gases, 'a ventilator may be employed tov overcome this diiiculty. n
From the above description rit wilLbe seen that by means of-my invention the execution of the" coal-distilling process proper needs not be altered in any way, but that the treatment of the' hitherto worthless lwaste-gases has only to take place in the mannerabove described before the waste-gases are discharged into thev chimney. The peculiarity it. Incase the draft of the ch1mney should of this new process is therefore particularly characterized by the fact, that not a single phase in the treatment of the. coke-oven gases is to vbe considered, but that by the n hases, a process, 4completein itself, 1s obtamed consisting in combination of several rst separa-ting the ammonia from the ases, then burning the gas while still containing the hydrogen sulfid thereby forming waste gases, still hot, and containing sulfur dioxid Y The gases of distillation are then led through the pipe 4 to the ammonia-Washer -5, the water being supplied through a pipe 6 at the top of said Washer. The amount of gas necessary -for heating the coke oven, still containing all its sulfur, is then led to the sulfur contained therein are .now burned.
header 7 from which distributing pipes 8 lead the gases to the mixers) to be mixed with the necessary quantityl of air, which charge is then ignited. The gases and the and the heat generated thereby is imparted to the coke-oven, the lire-gases being led around the latter to the bottom-chamber 10, from whence they are directed through pipes 12 to the tower 11. To the latter is also ledV the ammoniacal liquor of washer 5 through pipe 13 connected to the top of the tower wherein it drizzles through the ascending Waste-gases which are linally'discharged through pipe 14 into a chimney( not shown). While this liquor con-res into Contact with the Waste-gases, the ammonia combines with the sulfur trioxid and sulfur dioxid whereby a solution is formed which contains sulfate ofva'mmonium and sulite of ammonium respectively. The solution is finally removed from the tower by means of pipe 15 for further treatment.
I claim:
Process of obtaining ammonium sulfate and sulfite from the gases of dry distillation of fuel which consists in separating the tar from said gases, Washing the gases freed from tar to obtain an ammoniacal liquor, burning the gases freed from tar and ammonia to transform the sulfur contained therein into sulfur trioxid and sulfur dioxid, and
treating the gaseous products of combustion with said ammoniacal liquor to form ammonium sulfate and sulte.
