I, ALFRED KIRBY HUNTINGTON, of King's College Strand in the County of
Middlesex, Professor of Metallurgy, do hereby declare the nature of my invention
for "PROCESS FOR THE SEPARATION OF CARBONIC OXIDE FROM THE PRODUCTS OF
FURNACES OR GAS PRODUCERS" to be as follows:-
The products of many furnaces and of gas producers contain carbonic oxide
which is available as fuel, but this is generally mixed with a large proportion of
nitrogen which very much reduces the value of the products as combustibles. My
invention relates to means of separating from these mixed products the carbonic
oxide or a large portion thereof so that it may be employed as a combustible,
without the presence of the nitrogen or of a large proportion thereof. For this
purpose, I pass the products through a solution of cuprous chloride or over a series
of trays containing cuprous chloride, which is capable of absorbing a considerable
volume of carbonic oxide, but absorbs little or no nitrogen. The solution of
cuprous chloride may be made by dissolving chloride of copper in hydrochloric acid
or in a chloride solution such as ammonium or sodium chloride. I find the solution
of ammonium chloride is best for the purpose which I have in view. In order to
render the absorptive action more effective I prefer to conduct it under a pressure
of several atmospheres, for that purpose compressing the products by pumping
them into the absorbent vessels, allowing the free nitrogen to escape by a suitable
valve.
When the absorbent is saturated or nearly so, I relieve the pressure in the
absorbent vessel and, either by heating or by mechanical rarifaction, I liberate the
carbonic oxide that has been absorbed and collect it in suitable receptacles for use
as combustible.

Process for the Separation of Carbonic Oxide from the Products
of Furnaces or Gas Producers.
I, ALFRED KIRBY HUNTINGTON of Kings College, Strand in the County of
Middlesex, Professor of Metallurgy, do hereby declare the nature of my invention
for "PROCESS FOR THE SEPARATION OF CARBONIC OXIDE FROM THE PRODUCTS OF
FURNACES OR GAS PRODUCERS" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :—
The products of many furnaces and of gas producers contain carbonic oxide
which is available as fuel, but this is generally mixed with a large proportion of
nitrogen which very much reduces the value of the products as combustibles. My
invention relates to means of separating from these mixed products the carbonic
oxide or a large portion thereof so that it may be employed as a combustible,
without the presence of the nitrogen or of a large proportion thereof. For this
purpose I pass the products through a solution of cuprous chloride, which is capable
of absorbing a considerable volume of carbonic oxide, but absorbs little or no
nitrogen. The solution of cuprous chloride may be made by dissolving chloride of
copper in hydrochloric acid or in a chloride solution such as ammonium or sodium
chloride. I find the solution of ammonium chloride is best for the purpose which I
have in view. In order to render the absorptive action more effective I prefer to
conduct it under a pressure of several atmospheres for that purpose, compressing
the products by puinping them into the absorbent vessels, allowing the free
nitrogen to escape by a suitable valve. When the absorbent is saturated or nearly
so, I relieve the pressure in the absorbent vessel and by mechanical rarefaction I
liberate the carbonic oxide that had been absorbed and collect it in suitable
receptacles for use as combustible.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The process for separating carbonic oxide from the products of furnaces or gas
producers, substantially as herein described.
