of Kent, Professor of Chemistry, for the Invention of "IMPROVEMENTS IN
PURIFYING GAS, AND IN APPARATUS EMPLOYED THEREIN."

and deted the 4th June 1878
PROVISIONAL SPECIFICATION left by the said Charles William Heaton at
the Office of the Commissioners of Patents on the 4th June 1878.
CHARLES WILLIAM HEATON, of Lessness Heath, in the County of Kent, Professor
of Chemistry. "IMPROVEMENTS IN PURIFYING GAS, AND IN APPARATUS EMPLOYED
THEREIN."
My Invention has reference to the removal of compounds of sulphur and ammonia
and other impurities from gas, and it consists in washing the gas by means of a
spray or sprays of gas liquor, water, or other suitable liquid introduced into the
condenser or scrubber or other vessel, through which the gas passes, this mode of
washing being in lieu of or in addition to the scrubbing or washing of the gas by
means of coke, through which gas water or pure water flows, or other mechanical
methods as now ordinarily adopted.
In order to carry out my Invention I connect with the condenser, scrubber, or
other vessel in which the washing as aforesaid is to be effected a vessel containing
the liquid which has to be introduced into the condenser or scrubber in a state of
spray, such connection being conveniently formed by one or more pipes, which
terminate in nozzles in the condenser or scrubber or other vessel, and I force into
and through such pipes or connections ordinary or other suitable gas at a high
pressure so as to force forward the liquid and divide it into minute particles or
spray.

page_text: The conversion of the liquid to the state of spray, as above described, allows of
its coming into intimate contact with the gas in the condenser or scrubber, and the
gas is therefore quickly washed or purified.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles William Heaton in the Great Seal Patent Office on the 4th
December 1878.
CHARLES WILLIAM HEATON, of Lessness Heath, in the County of Kent, Professor
of Chemistry. "IMPROVEMENTS IN PURIFYING GAS, AND IN APPARATUS EMPLOYED
THEREIN.'
"
My Invention has reference to the removal of compounds of sulphur and ammonia
and other impurities from gas, and it consists in washing the gas by means of a
fine spray or sprays of gas liquor, water, or other suitable liquid, forced by means
of gas or vapor, as herein-after described, into the condenser or scrubber, or other
vessel, through which the gas passes, this mode of washing being in lieu of or in
addition to the scrubbing or washing of the gas by means of coke, through which
gas water or pure water flows, or other mechanical methods, as now ordinarily
adopted.
In order to carry out my Invention I connect with the condenser, scrubber,
ог other vessel in which the washing as aforesaid is to be effected, a
vessel containing the liquid which has to be introduced into the condenser or
scrubber in the state of spray, such connection being conveniently formed by one or
more pipes, which terminate in nozzles in the condenser or scrubber or other
vessel, and I force into and through such pipes or connections ordinary or otlier
suitable gas or vapor at a high pressure so as to force forward the liquid; and
divide it into minute particles or fine spray.
The conversion of the liquid to the state of fine spray, as above described, allows
of its coming into intimate contact with the gas in the condenser, scrubber, or other
vessel, and the gas is therefore quickly washed and purified.
In the accompanying Drawing I have shown, by way of example, an apparatus
suitable for carrying my Invention into effect.
a represents a condenser or other vessel, through which the gas passes; b is the
inlet for the gas to such vessel, and c, the outlet; d is a vessel containing the gas
liquor or other liquid which has to be introduced into the condenser or vessel a ;
e, e, are pipes leading from the vessel d into the vessel a, where they terminate in
nozzles ff; 9, 9, are pipes terminating in cones or nozzles h, h, in enlargements of
the pipes e, e. The pipes g, g, communicate with any suitable apparatus by which
ordinary or other suitable gas or vapor at a high pressure is forced into and through
them. The jets of this gas or vapour meeting the liquid which flows down the
pipes e, e, force it through the nozzles f, f, so that it enters and fills the condenser a
in the form of minute particles or fine spray.

page_text: And having now described the nature of my said Invention and in what manner
the same is to be performed, I declare that I claim,―
First. Purifying gas by washing it by means of gas liquor, water, or other
suitable liquid in the form of fine spray or minute particles, forced by gas or vapor
into a condenser, scrubber, or other vessel, through which the gas passes, sub-
stantially as herein-before described.
Second. Constructing apparatus for purifying or washing gas by means of
liquid in the form of fine spray or minute particles, substantially as herein-before
described.
In witness whereof, I, the said Charles William Heaton, have hereunto set my
hand and seal, this Third day of December, One thousand eight hundred
and seventy-eight.
