Petroleum, Rosin, and the like.
GEORGE THOMAS BEILBY of Saint Kitts, Slateford County of Midlothian, Chemical
Engineer and JAMES BRAND MARTHUR, Oakbank Midcalder, County of Midlothian,
Chemist, do hereby declare the nature of our invention for UTILISING HYDROCARDON
GASES OBTAINED IN THE DISTILLATION OF PETROLEUM ROSIN AND THE LIKE, to
be as follows:-
Our invention refers to the collection and utilization of hydrocarbon gases which
are sometimes produced in the Stills in which Petroleum, Rosin or Mineral Oils are
being distilled. With the object of collecting and utilising these waste gases we lute
the end of the condensing worm of the still in any convenient way so that while the
liquid distillate flows to the receiving tanks the gas passes away by a separate pipe.
The gas pipes from any number of still condensers are connected, by means of suitable
valves and bye-passes, with a general system of collecting pipes.
To avoid throwing a back pressure on the vapour within the still a sufficient exhaust
may be maintained by means of Steam Ejectors or their equivalent.
The gas from the collecting pipes is led to receivers, either directly or through
supplementary condensers, washers or purifiers.
The collected and recovered gas from Oil Stills is a valuable illuminating agent for
general use and is also suitable for compressing in reservoirs for illuminating Railway
carriages or Tramway cars or for other similar purposes.
The collected and recovered gas is also a valuable heating agent and may be used
as a fuel in furnaces or for the production of motive power in Gas Engines.

Utilising Hydrocarbon Gases Obtained in the Distillation of
Petroleum, Rosin, and the like.
GEORGE THOMAS BEILBY of St. Kitts, Slateford in the County of Midlothian,
Chemical Engineer and JAMES BRAND MCARTHUR of Oakbank Midcalder in the
County of Midlothian, Chemist do hereby declare the nature of our invention for
UTILISING HYDROCARBON GASES OBTAINED IN THE DISTILLATION OF PETROLEUM,
ROSIN AND THE LIKE and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our invention refers to the collection and utilization of hydrocarbon gases which
are sometimes produced in stills in which Petroleum, Rosin or Mineral Oils are being
distilled. With the object of collecting and utilising these gases we lute the end of
the condensing worm of the still in any convenient way so that while the liquid
distillate flows to receiving tanks the gas passes away by a separate pipe.
The gas pipes from any number of still condensers are connected, by means of
suitable valves and bye-passes, with a general system of collecting pipes.
To avoid throwing
a back pressure on the vapour within the still, a sufficient
exhaust may be maintained by means of steam ejectors or their equivalent.
The gas from the collecting pipes is led to receivers, either directly or through
supplementary condensers, washers or purifiers.
We have found that crude Shale Oil while undergoing distillation in the form of still
in ordinary use, produces gas at the rate of one to one and a half cubic feet per gallon
of Crude Oil distilled. This gas after being properly cooled and condensed has an
illuminating power of from thirty to forty candles. Petroleum & Mineral Oil residues
sometimes produce a larger volume of gas than this.
The gas collected and recovered from oil stills may be applied to any of the uses to
which coal gas or ordinary oil gas are applied.
Having now particularly described and ascertained the nature of our said invention
and the manner in which the same is to be performed, we declare that what we
claim is
The collection and utilization of hydrocarbon gases from stills in which Petroleum,
Rosin or mineral oil is being distilled, in the manner described in our foregoing
specification.
