Improvements in Means or Apparatus for Distilling, applicable also
for Enriching Gases by Means of Hydrocarbons.
I PAUL DVORKOVITZ of Devonshire Chambers, 16 Bishopsgate Street Without,
in the City of London, Chemist, do hereby declare the nature of my invention to
be as follows:-
The object of my invention is to provide means or apparatus whereby a very
efficient distillation of tarry or other matters (I will refer to them as tars) can be
effected and when desired the enriching of gases be effected by means of the same
apparatus, the apparatus being simple and inexpensive in construction as compared
with other apparatus for similar purposes and not being liable to readily get out of
order or become obstructed.
An apparatus constructed according to my invention consists of a closed vessel
having at bottom coils or the equivalents for steam or other heating agent and
means for feeding in the matter to be distilled and an outlet by which it can run
off after the products of distillation have been removed therefrom. I prefer to use
two or more such vessels (say three for instance, each succeeding vessel being at a
lower level than, or beneath, that preceding it the outlet from each vessel being at
such a level and covered by a cap descending to near the bottom of the vessel so
that the tars run off from the lower part thereof where the tars are heavier. The
inlet for tar to all the vessels should descend to near the bottom of each vessel and
the pipes should be of increasing area so as to allow of a free passage of the tars
as they become thicker.
The upper parts of the vessels are provided with passages for the products of
distillation from vessel to vessel and from the last vessel of the series where
several vessels are used, and where the apparatus is used for enriching gas the
vessel or the lower vessel or the lowest vessel of the series is provided with an
inlet for the gas which passes over the layer or layers of tarry matter being
subjected to heat and takes up the enriching hydrocarbons given off.
In order to improve the action of the apparatus the tarry matters may have air
or gas admitted to them beneath the layers thereof and when the apparatus is used
for enriching gas the gas used for thus being passed into the layers may be a small
proportion of the gas which is being enriched the gas (or the air where that is
used) being passed into the vessel or vessels by means of perforated pipes laid at
or near the bottom of the vessels and in proximity to the pipes or coils through
which the steam or heating agent is passed.

I, PAUL DVORKOVITZ of Devonshire Chambers 16 Bishopsgate Street Without
in the City of London Chemist do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
The object of my invention is to provide means or apparatus whereby a very
efficient distillation of tarry or other matters (I will refer to them as tars) can be
effected and when desired the enriching of gases be effected by means of the same
apparatus, the apparatus being simple and inexpensive in construction as compared
with other apparatus for similar purposes and not being liable to readily get out of
order or become obstructed.
In order that my invention may be properly understood I will now proceed to
describe the same with reference to the accompanying drawings in which Figure 1
is a longitudinal vertical section and Figure 2 a horizontal section and Figure 3 an
end elevation of distilling or gas enriching apparatus constructed according to my
said invention.
Like letters of reference indicate like parts throughout the drawings.
In carrying my invention into practice provide a closed vessel A having at
bottom coils or the equivalents B for steam or other heating agent and means such
for example as a pipe C, for feeding in the matter to be distilled and an outlet D, by
which it can run off after the products of distillation have been removed therefrom.
I prefer to use two or more such vessels say for instance three as shown in the
drawings wherein they are respectively marked A A¹ A2, each succeeding vessel
being at a lower level than, or beneath, that preceding it. The outlet D from
each vessel is at such a level and covered by a cap D' descending to near the
bottom of the vessel that the tars run off from the lower part thereof where these
tars are heavier. The inlets for tar, that is to say the pipe C, of the vessel A and
pipes D of the vessels A¹ and A2 should descend to near the bottom of each vessel
and these pipes should be of increasing area so as to allow of a free passage of the
tars as they become thicker.
The upper part of the vessel A is provided with a passage E for the products of
distillation and, where a series of vessels is used as shown in the drawings, each of
the other vessels is provided with a similar passage El connected with the vessel
next in the series. If the apparatus is to be used for enriching gas, the vessel A,
if only one he used or the lower or lowest vessel if more than one be used is
provided with an inlet F, for the gas which latter passes over the layer or layers
of tarry matter being subjected to heat and takes up the enriching hydrocarbons
given off the surface levels of these layers of tarry matter are indicated by the
dot-and-dash lines G in Figure 1.
In order to improve the action of the apparatus the tarry matters may have air
or gas admitted to them, beneath the layers thereof, and when the apparatus is
used for enriching gas, the gas used for thus being passed into the layers may be a
small proportion of the gas which is being enriched, the gas (or the air where that
is used) being passed into the vessel or vessels by means of perforated pipes H
laid at or near the bottom of the vessels A A' A³, and in proximity to the pipes or
coils B, through which the steam or heating agent is passed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manuer the same is to be performed I declare that what I
claim is:-
1. In apparatus for distilling tarry or other matters the combination with e

page_text: closed vessel having an outlet for the products of distillation, of a heating coil or
equivalent at the bottom thereof, an inlet for the matter to be distilled and an
outlet covered by a cap such as D¹ descending to near the bottom of the vessel
substantially as hereinbefore described with reference to the accompanying
drawings.
2. In apparatus for distilling tarry or other matters or for enriching gas the
combination with a closed vessel having an inlet and an outlet near the top thereof
of a beating coil or equivalent at the bottom thereof, an inlet for the matter to be
distilled or for the gas-enriching agent, a covered outlet such as D, D¹ for the said
matter or agent and a perforated pipe or equivalent near the bottom of the vessel
substantially as and for the purpose hereinbefore described with reference to the
accompanying drawings.
3. In apparatus for distilling tarry or other matters or for enriching gas the
employment of two or more vessels and sets of appurtenances such as claimed in
the last preceding claim, combined, arranged and operating substantially as
herein before described with reference to the accompanying drawings.
