An Improved Column for Condensing, Absorbing, Heating,
Distilling, and otherwise Treating Gases and Liquids.
I, HEINRICH HIRZEL of 13 Nonnenstrasse, Leipzig-Plagwitz, in the Empire of
Germany, Professor, do hereby declare the nature of this invention and in what
manner the same is to be perforined, to be particularly described and ascertained in
aud by the following statement :-
This invention has for its object a column with a heating and cooling device in
the separate dishes or chambers of the columu, whereby according as the substances
or liquids are to be cooled or heated, cold or refrigerating liquids or hot liquids or
steam may be passed through the dishes in closed pipes, and in addition for
distilling purposes steam may be directly convoyed iuto the column from below.
In this manner in mixtures of liquids of different boiling points the lighter
boiling constituents may be conveniently distilled off, aud further with mixtures of
gases and steam passing through the columns the more easily condensed substances
may be condeused by cooling in the column dishes, or absorbed by liquids passing
through the column."
Thus the same column is applicable for condensing, absorbing and distilling
purposes according as it is refrigerated or heated or as steam is directly conveycil
to it.
In the accompanying drawing, Figures 1-3, ropresent such a column apparatus,
Figure 1 being a vertical section, Figure 2 a vertical clevation, Figure 3 a
horizontal section on the line indicated by X-X in Figure 1.
The pipes D arranged in each separate section or chamber A either in com-
munication with those of adjacent chambers or forming a separate sories for each
chamber may be employed for cooling or for heating purposes. In the one case
cold or refrigerating liquids or iced liquide, in the other hot liquids or steam may be
passed through the pipes D.
•
For distillation purposes, a steam inlet valve vis provided below the lowest dish
of the column, through which valve steam may be directly convoyed into the
apparatus to pass through all the dishes B of the column upwards. In many
mixtures of liquids, the steam evaporates, the specifically lighter liquid and the
mixture of vapour escape at the top of the column, and is submitted in any suitable
manuer to the necessary further treatment.
Such a columu provided with cooling, hoating and direct steam inlet devices may
be employed for the most varied purposes, such for instance as when a cooling
liquid is employed, for catching the benzole contained in hot coke oven gases, on
the passing of wash oil through the column, and on the heating and passing of
direct steam through the column for the separation of benzole vapour (mixed with
steam) from wash oil saturated with benzole, and so forth.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A column for treating gases and liquids characterised by an arrangement of pipes
placed in each chamber or dish of the column and adapted to receive or circulate
cooling or warming gases or liquids, the pipes of each chamber being either in com
munication with those of adiacent chambers or forming a separate series for each

page_text: chamber, whereby in conjunction with a direct steam inlet device arranged below
the lowest dish of the column, the apparatus is applicable for condensing,
absorbing, distilling and henting purposes, substantially as hereinbefore set forth.
