IMPROVEMENTS IN THE PURIFICATION OF COAL GAS OR OF OTHER GASES CONTAINING AMMONIA OR AMMONIACAL COMPOUNDS
Year: 1884

page_text: I, ASTLEY PASTON PRICE of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of said Invention for "IMPROVEMENTS
IN THE PURIFICATION OF COAL GAS OR OF OTHER GASES CONTAINING AMMONIA
OR AMMONIACAL COMPOUNDS" to be as follows:-
This Invention relates to an improved method of effecting the purification of
Coal Gas or of other Gases containing ammonia or ammoniacal compounds or
products and it consists in the employment for such purpose of what are known as
the Bisulphates or of the acid sulphates of the Alkalies such for example as the
Bisulphate of Soda or of the acid sulphates of soda or of the Bisulphate of Potash
or of the acid sulphates of Potash or of the Bisulphate or acid sulphates of
Ammonia or of the Bisulphite or of the acid Sulphites of Soda or of Potash or of
Ammonia or of the acid Phosphates of Soda or of Potash or ammonia either in
a divided condition or in solution. By the employment of such Bisulphates or of
the acid Sulphates or of the Bisulphites or acid Sulphites of Soda or of Potash
or of Ammonia or of the acid Phosphates of Soda or Potash or Ammonia. The
Ammonia existing in the Ammoniacal compounds or products contained in the
impure coal gas or in other gases is absorbed and separated and from the resulting
compound or compounds containing Ammonia the same may be subsequently
obtained.
In carrying out my Invention the Bisulphates or Acid Sulphates or the Bisulphites
or acid Sulphites or the acid Phosphates of Soda or of Potash or of Ammonia may
be employed either in a solid or in a divided condition or in solution. When
employed in a solid or in a divided condition they may be used either alone or
mixed with an inert body so as to render them more pervious to the passage of the
gas or the gases under treatment and may be placed in purifyers similar to those
now employed in Gas Works for the use of Lime or of Oxide of Iron or otherwise
or the before mentioned Bisulphates or acid sulphates or the Bisulphite or the
acid sulphites of Potash or of Soda or of Ammonia or the acid Phosphates of
Potash or of Soda or of Ammonia may be employed in solution in a manner
similar to that in which water is, or other solutions are now employed viz in what
are known as scrubbers or washers or otherwise.
The product or products resulting may then be treated by any well known
means in order that the ammonia contained therein may be obtained therefrom.

Gentleman do hereby declare the nature of said invention for "IMPROVEMENTS
IN THE PURIFICATION OF COAL GAS OR OF OTHER GASES CONTAINING AMMONIA
OR AMMONIACAL COMPOUNDS" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
This Invention relates to an improved method of effecting the purification of
Coal Gas or of other Gases' containing ammonia or ammoniacal compounds or
products derived or emanating either from Blast or other Furnaces or from Coké
Ovens or from other sources and it consists in the employment for such purpose of
what are known as the Bisulphates or of the acid Sulphates of the Alkalies such
for example as the Bisulphate of Soda or of the acid Sulphates of Soda or of the
Bisulphate of Potash or of the acid Sulphates of Potash or of the Bisulphates or
acid Sulphates of ammonia or of the Bisulphites or of acid Sulphites of Soda
or of Potash or of Ammonia or of the acid Phosphates of Soda or of Potash or
ammonia either in a divided condition or in solution-By the employment of such
Bisulphates or of the acid sulphates or of the Bisulphites or of the acid sulphites
of soda or of Potash or of ammonia or of the acid Phosphates of Soda or Potasli
or ammonia, the ammonia existing in either the Gases or in the ammoniacal
compounds or products contained in the impure coal gas or in the other gases is
absorbed and separated and from the resulting compound or compounds containing
ammonia the same may be subsequently obtained.
In carrying out my Invention the Bisulphates or the acid Sulphates or the
Bisulphites or acid Sulphites, or the acid Phosphates of Soda or of Potash or of
ammonia may be employed either in a solid or in a divided condition or in
solution-When employed in a solid or in a divided condition they may be used
either alone or mixed with an inert body so as to render them more pervious to the
passage of the gas or the gases and may be placed in purifiers similar to those now
employed in Gas Works for the use of Lime or of Oxide of iron or otherwise or
the before mentioned Bisulpbates or acid sulphates or the Bisulphites or the acid
sulphites of Potash or of Soda or of Ammonia may be employed in solution in
a imanner similar to that in which water or other solutions is or are now employed
viz in what are known as scrubbers or washers or otherwise.
The product or products resulting may then be treated by any well known' means
in order that the ammonia contained therein may be obtained therefrom.
I'declare that I make no claim to the employment of the Bisulphates of Potash
or of Soda or of Ammonia for the purification of Coal Gas-that is to say of
illuminating Gas-But what I claim is
First The employment and use of the Bisulphites and of the acid Sulphites of
Potash of Soda and, of Ammonia for effecting the purification of coal Gas or of
other gases containing ammonia or ammoniacal compounds substantially in the
manner and for the purpose hereinbefore described.

page_text: Second: The employment of the Bisulphates and of the acid Sulphates of
Potash of Soda and of Ammonia for the purpose of treating the gases other than
illuminating or coal gas so as to obtain Ammonia therefrom substantially in the
manner as herein before described.
