"
Our Invention relates to Improvements in effecting the Extraction and
separation of the soluble ammoniacal compounds contained in impure coal gas and
consists in the Employment for such purpose of water or of Ammoniacal liquor
which has been artificially reduced in temperature the same being employed for
the purpose of washing or scrubbing impure coal gas in a manner either similar to
that now generally adopted or in any other convenient manner In carrying out
our Invention the following arrangement may be adopted viz The water or the
Ammoniacal liquor which has or have been artificially cooled and which is or are
to be employed for the purposes of separating the soluble ammoniacal compounds
from impure coal gas is or are brought in contact with the impure coal gas in a
washer scrubber or in any other suitable apparatus as is well understood by the
employment of this Invention apparatus of much smaller dimensions may be
employed than that now in use.

now in use.
In carrying out our Invention we submit the impure gas contained in or
passing through a scrubber or washer to the action of water or of Ammoniacal
Liquor or of mixtures of the same such water Ammoniacal Liquor or mixtures of
the same being submitted to an artificial cooling process, and employed by
preference at or about a temperature of from about 32° Fahrenheit to about
42° Fahrenheit.
Having now described and particularly ascertained the nature of our said
