To all whom it may concern,.-
Be it known that I, HEINRICH PROPFE, a subject of the Emperor of Germany, and resident at Mannheim, Germany, have invented new and useful Improvements in Distilling Apparatus, (for which Ihave obtained patents as follows, viz.: in Germany, No. 55,025, dated January 30, 1890; in France, No. 203,865, dated February 19, 1890; in Switzerland, No. 1,956, dated February19, 1890; in England, No. 2,955, dated February 24, 1890; in Belgium, No. 89,650, dated February 27, 1890; in Italy, XXIV, 27,349, LIV, 88, dated April 21, 1890; in Spain, N o. 10,689, dated May 24, 1890, and in Austria-Hungary, No. 8,574 and No. 22,624, dated June 12, 1890,) of which the following is a specification.
The principal object of this invention is to provide economical means for the distillation of coal-tar in gas-works or other places by a continuous process.
I will iirst describe my apparatus with reference to the accompanying drawings, and afterward point out its novelty in a claim.
Figure 1 represents a longitudinal section of the apparatus, the central part being broken away to reduce the length. Fig. 2 represents a transverse section in the line a b of Fig. 1.
The body of the apparatus consists of an elongated tight wrought-iron box divided by partitions S into a train of separate stills or compartments-eight, for example-A A2 A7 A8, which communicatewith each other below the partitions. Each compartment is provided With a still-head H H8 for the purpose of carrying off the distillate.l Under the compartment or still A8 at one end of the train is a furnace B, through which a flue runs under the several stills in the train.
T is a feed-pipe, which enters the compart-V ment A farthest from the furnace or source of heat, whence the tar falls under the partitions S through the several stills or compartments successively.
s is the exit-pipe which runs through the whole train of stills or compartments and under the partitions S, but is only open to the compartment or still As next the furnace or source of heat. Its outlet is beyond the compartment A', which is farthest from the fur- Vand successively in the others,
nace, where it is provided with an overflow swan-neck P or a cock, by which the level of the tar is kept constantthroughout the several compartments of the apparatus.
The operation of the apparatus is as follows: At the start the apparatus is filled with tar to about two-thirds its height. As the compartments are separated from each other by the hydraulic seal of the partitions S dipping into the tar, the distillation begins first in the compartment A8 nearest the furnace, whereby the contents of the compartment A8 are gradually converted into pitch by the continued heating. When this stage (which is easily recognized bytesting the nature of the distillate) is reached, the tar is supplied at T continuously to the compartment A farthest from the furnace, whence it passes below the first partition S to the next compartment A2, and so on until it reaches the compartment A8 nearest the furnace. In its passagethrough the several compartments the temperature of the tar is constantly increasing, and consequently the distillates passing over from successive compartments have progressively higher boiling-points. The inflow of the tar and theheating of the apparatus are gradually regulated in such manner that, for example, from the first to the fourth compartments only so-called forerunnings and Water distill continuously, from the fifth and sixth socalled light oil, and from the seventh and eighth green oil. It is desirable that a stream of superheated steam be introduced into the last two compartments, as the distillation of the so-called green oil is thereby considerably hastened. The pitch passing out from the last compartment Yflows slowly through the outlet-tube s, passing through the several compartments in to the fiow of the tar through the compartments, whereby it is gradually cooled and passes out at such a comparatively low temperature that it will not ignite, while at the same time that the pitch is thus gradually cooled its heat contributes to the heating of the contents of the tar in the several compartments.
