Blackburn, in the County of Lancaster, Patent Agent, for an Invention of
“IMPROVEMENTS IN EXTRACTING AMMONIA DURING THE DISTILLATION OF
AZOTIC SUBSTANCES." A communication from abroad by Th. Richters, of
Breslau, in the Empiro of Germany.
PROVISIONAL SPECIFICATION left by the said Walter Brierley at the Office
of the Commissioners of Patents on the 13th July 1880.
WALTER BRIERLEY, of Halifax, in the County of York, and Blackburn, in the
County of Lancaster, Patent Agent. "IMPROVEMENTS IN EXTRACTING AMMONIA
DURING THE DISTILLATION OF AZOTIC SUBSTANCES." A communication from
abroad by Th. Richters, of Breslau, in the Empire of Germany.
For purpose aforesaid in the dry distillation of azotic substances I employ in
conjunction with a distilling apparatus superheated steam or water.
The process is based on the following chemical observation:— -When azotic
substances like coal, peat, brown coal, bones, animal rubbish of all kind, viz., old
leather, felt, wool, hairs, etc., are heated, a decomposition of the organic substance
takes place. A part of the nitrogen escapes as ammonia, while another remains as
azotic carbon, which latter, only when in a higher temperature, is transformed into
nitrogen and carbon.
The steam is discharged through this azotic-carbon, the water and the azotic
carbon are decomposed, and ammonia and carbonic acid or carbonic oxyd arise.
Superheated steam is the best for this decomposition, and the ammonia produced in
the form of carbonate, hydro-chlorate, or sulphate of ammonia is readily secured.

The process is based on the following chemical observation -When azotic
substances like coal, peat, brown coal, bones, animal rubbish of all kind, viz., old
leather, felt, wool, hairs, etc., are heated, a decomposition of the organic substanco
takes place, a part of the nitrogen escapes as ammonia, while another remains as
azotic carbon, which latter, only when in a higher temperature, is transformed into
nitrogen and carbon.
The steam is discharged through this azotic carbon, the water and the azotic
carbon are decomposed, and ammonia and carbonic acid or carbonic oxyd arise.
Superheated steam is the best for this decomposition, and the ammonia produced in
the form of carbonate, bydrochlorate, or sulphate of ammonia, is readily secured.
Such being the nature of this-Invention, the following is a complete description
thereof.
The process is based on the following chemical observations :-
Whon azotic substances like coal, peat, brown-coal, bones, animal rubbish of all
kind, viz., old leather, felt, wool, hairs, etc., are heated, a decomposition of the organic
substance takes place, a part of the nitrogen escapes as ammonia, while another
remains as azotic carbon, which latter, only when at a higher temperature, is
transformed into nitrogen and carbon. If steam be passed through this azotic
carbon the water and the ozatic carbon are decomposed, and ammonia and carbonic
acid or carbonic oxyd arise; superheated steain is the best for effecting this
decomposition.
In witness whereof, I, the said Walter Brierley, have hereunto set my hand
and seal, this Twelfth day of January, in the year of our Lord One
thousand eight hundred and eighty one.
