THE PURIFICATION OF ALCOHOL AND IN APPARATUS
The spirit is combined under pressure with carbonic acid gas and then led to a
tank where the gas is liberated from the spirit carrying with it the fusel oil.
For producing the carbonic acid gas it is preferred to employ the apparatus
commonly used in the manufacture of aërated waters and consisting of the
generator for making the gas, the washing apparatus and gas receiver, and the
saturating or mixing apparatus consisting of the vessel or container compressing
pump and usual accessories. In addition to these there is a suitable pipe leading
to an open vessel and preferably carried over the top down the side and across the
bottom, the latter portion being perforated.
In working this process the gas is generated, washed, and collected and delivered
to the mixing vessel where the spirit is also admitted and the two combined and
compressed to form 10 to 15 atmospheres. The combined spirit and gas is now led
by the pipe to the open vessel where it escapes by the perforations in the pipe the

alcohol wbich remains behind in the vessel is led off to be rectified in the usual
manner.
To use this process in distilleries which produce alcohol from farinaceous
substances, beetroot molasses, and various other substances, no alteration need be
made in the existing apparatus, but the following used in manufacturing aërated
waters must be added.
: In the accompanying drawings Fig. 1 is the carbonic acid gas producer; Fig. 2
the washing apparatus; Fig. 3 the receiver; Fig. 4 is the saturating apparatus ;
Fig 5 the evaporating tank.
The carbonic acid gas is generated in Fig. 1, washed in Fig. 2, collected in the
receivers Fig 3 and passes by the pipe A to the force pump B Fig. 4 and by the
pipe C to the mixing vessel D. The foregoing apparatus being that commonly
used in the manufacture of aërated waters and well known to persons skilled in
the manufacture, needs no further description here.
The spirit to be operated upon is also conveyed to the mixing vessel D where it
is combined and intimately mixed with the carbonic acid under a pressure of from
10 to 15 atmospheres. When this mixing is completely effected the aërated spirit
is led by a suitable pipe E, by the opening of the valve E', to the evaporating tank
Fig. 5, in which preferably upon the bottom is placed the end of pipe Ẹ perforated
as shown or formed into a rose, but the former plan is preferable as it allows free
escape of the spirit and also still more finely divides it. The tank Fig, 5. should
be shallow and of large area and the gas escapes here carrying with it the fusel
oil &c and leaving a thoroughly defacated product which is then passed to the
usual rectifying still.
Having now described this invention and the method of performing the same
as communicated to me by my foreign correspondent I wish it to be understood

page_text: what I claim and desire to protect under the hereinbefore in part recited
rs Patent is :-
-The process for defacating or purifying alcohol by first saturating it with
carbonic acid gas and then liberating the saturated spirit in an evaporating
tank, substantially as described and illustrated.
d:-The combination with the ordinary apparatus for producing and mixing
carbonic acid gas, of the evaporating tank and perforated pipe E sub-
stantially as described and illustrated whereby the spirit is mixed with
carbonic acid gas, which, when liberated in said evaporating tank, carries
with it the fusel oils, vapours and the like.
In witness whereof I the said Alfred Julius Boult have hereunto set my.
hand and seal this thirtieth day of March in the year of Our Lord one
thousand eight hundred and eighty three.
