No. 7,743, and in Norway September 29, 1885.
To aZZ whom, it may concern.-
Be it known that we, EMIL' HIiNIscH and MAX SoHRoEDER, subjects of the King of Prussia, residing at the village of Hamborn, in the Kingdom of Prussia, German Empire, have invented a new and useful Improved Process of Obtaining Sulphur, of which the following is a specification.
Our invention relates to a process of obtaining sulphur from furnace calcinatiou or roasting gases in which sulphurous acid is present; and it consists in bringing the sulphurous acid in the gaseous mixtures not direct to reduction, but only after it has been separated from the other injurious or neutral components accompanying it, this being effected by maintaining the same at a glowing heat within a closed space after it has been passed through or over a glowing bed of fuel.
The process is carried out as follows: Ve separate the sulphurous acid from the other gases accompanying it by causing the furnace, or calcination or roasting gases to flow upward in a tower against a downward flow therein of cold water in the form of rain. The water absorbs the sulphurous acid, but not the gases mixed therewith, (nitrogen, oxygen, carbonic acid.) The watery SO solutions (anhydrous sulphurous-acid solutions) are heated in a series of closed lead pans, by steam or otherwise, to boiling heat, and in this manner we obtain sulphurous acidin the form of gas. The watervapor taken up and carried along in this portion of the process is separated from the evolved gas by means of a worm or coil of pipe. We
then reduce the sulphurous acid,for which pur' pose we employ the apparatus shown in the accompanying drawing, in which the figure is avertical longitudinal section of the apparatus.
lVe conduct the sulphurous acid through the pipe a into the cylinder 1), which is charged with coal, coke, or charcoal fuel, and is heated to a glowing heat. The sulphurous acid,which has been half reduced in the cylinder 1), but is mixed with sulphur-vapors and carbon oxides, 850., is caused to pass to the cylinder 6 through the connecting-pipe d. The cylinder 6 is filled with fire-bricks or other suitable fireproof material. It is impinged upon and heated by the hot gases coming from the cylinder 1) through the apertures f. We now conduct the as yet unreduced acid through the glowing mass of fire-brick in the cylinder 6 in a downward direction. By this latter means we opcrate the transformation of the second half of 5 5 the sulphurous acid in conjunction with the formation of sulphur-vapor and carbonic acid. We conduct these gases out of the cylinder 6 into the preliminary condensing-chamber g,
and thence to the main condensing-chamber h, at the end of which the carbon oxides pass out. The sulphur-vapors obtained in this way are condensed in g and h into the form of liquid sulphur, which is withdrawn through the pipe 0. 6 5
We are well aware that sulphurous acid has before this been reduced to sulphur by conducting it through a glowing bed of fuel. In this process, however, a considerable expenditure of fuel is required for heatingrthe gases comparatively poor in S0,, which mostly consists of atmospheric nitrogen and oxygen. Further, the free oxygen contained in the gases causes a large portion of the reducing-fuel to be uselessly consumed; also, large quantities of neutral gases are generated, which are an obstacle to the reduction of the sulphurous acid to sulphur, and also to the reduction of the separated finely-distributed sulphur. Finally, while one portion of the S0 molecules are quite unaffected the other portion, on the contrary, is reduced to carburet of sulphur. The reducing process in conducting the S0 through or over glowing fuel does not proceed precisely according to the formula SO,''[O:OO,+S, but rather agaseous mixture is obtained, which consists more or less of carbonic acid, carbonic oxide, sulphurous acid, sulphur-vapor, carburet of sulphur, and, under certain circumstances, hydrogen sulphide and 0 water-vapor. By the employment of a longer bed of fuel and by conducting the SO, more slowly through the same or over the same the contents in SO would decrease; but, on the other hand, carburet of sulphur and the car- 5 bonic oxysulphide would increase in quantity. By the employment ofa shorter bed of fuel and quicker through-passage the last-mentioned gases would be present in a lesser degree; but, on the other hand, the. larger por- 10o tion of the sulphurous acid would remain unreduced; hence it is evident that SO gases which have been conducted through or over glowing fuel must remain afurther interval of 5 time as a glowing heat and excluded from any further influence. For this reason we cause the gases to pass through a chamber containing glowing fire-bricks. By our process We obtain carbonic acid and sulphur only.
What we claim as our invention, and desire to secure by Letters Patent, is-
The process of obtaining sulphur from furnace or calcination or roasting or similar gases by passing them through water, then separatr 5 ing the sulphurousacid gas absorbed from the EMIL HANIsoH. MAX SOHROEDER.
