Memphis daily appeal. [volume] (Memphis, Tenn.) 1847-1886, 1871-12-28
TO GAS CONSUMERS.

The idea hss gone abroad that the Memphis
Gasligh1 company was ready % abandon what
IS termed the naphtha process In The manu-
facture OF gas. There never was 9 greater
faliacy.
When We consider the material used-the
essential oil Of petroleum., scarcely merchant
able for any other nse-tne r1cnness OF the gas
produced, requiring, when used as naphtha
gas alone, TO be diluted with forty-two per
cent. Of air to reduce tt TO something like the
standard Of gss measured ~ ys1 Sa1ndhie-P0wefl ,h
ty, certainty, and, under proper circumstance,
the economy with which IL can be produced.
lIs use must be regarded as an advanced move
ment in gas manufacture, which should re-
ceive the attention OF both practical and sci
entihc men.
We have found it best to use this process in
conjunction with the manufacture Of GOAL gas
First, because we have market for the resi-
dual products, coke and tar, at fair prices.
Second, because our works and apparatus
we're constructed for the distilation of bltu-
minOus Goals.
The late complaints about the quality of gas
supplied TO the city grew out Of the fact that
on account OF the stock OF naphtha running
short, and some changes being made at the
works, the gas in the holders for few nights
was nearly pure coal gas, quite equal TO the
standard formerly produced by this company.
The change from the use OF usphtha was as
perceivsble and marked as II the burners had
undergone a partial eclipse, and complaints
as natural as II one accustomed to glasses had
attempted to lay them aside, suddenly,
By slight change made In the connections
with our DAEQInA ga meier hQlullLluE only
pure napbtha gas into the mixer, we can with
ease infect such quantity Of this rich, mo
dOrous and disinfectant gas into the holders
as 10 Immediately overcome any objections as
10 the quality of the gas throughout the city,
not only raising the Illuminating power to any
given standard, but absorbing TO great extent
Tie trace of sulphufetted hydrogen which
always imparts bad odor TO the best coal
This we do not claim as a discovery, but the
experimental test of the use of pure naphtha
frrr rraraz fr1ur md ffGfI
On the evening Of the 20th, about four
O'Clock, we had succeeded in getting ready for
trying the effect on 8 large scale, Of what is
known in chemistry as gaseous diffusion with
out regard 10 specific gravity. Not the uni
form 1nterminglng Of gases, for that Yves q
known scientinc fact, but the time required
for complete mixture Of gases through ths
Mains III extendedl tventy-eight miles In
length.
The holders contained about 10000 feet OF
gas, with q make Of about fifteen 20 eighteen
thousand feet per hour, when we commenced
turning in the pure nRphtha gas running only
two benches OF So aud making at the rate OF
about eight thousand cubic feet per hour. The
phOtometer (Sugg's make, London measured
the coal gas in the mains at fourteen candle
AS soon as we observed from the test lights
the naphtba gss filing the pipes, we noted
the candle power of the gas In the street mains
to begin rapidly aud steadily 70 ascend, and
In twenty minutes more We found II was
eighteen candle-poweT-
Going Immediately to the office in the heart
OF the city, 70 note the effect there, we found
every one enquiring what had occurred, and
surprised at the increased brtl1ancy of the
light.
Thus in twenty minutes the Illuminating
standard OF coal gas, fourteen candle-power,
was raised to eighteen.
By no other process known 10 modern sci
ence and practice can such results be pro-
duced so rapidly. In the ordinary manufac-
ture OF coal gas, complaints as to quality can
only be remedied By gradual process, which
generally comes too late 10 meet com plaints
By this method alone Is the effect immediate.
We can, therefore, assure the public that
hereafter any just complaints as to the Hum
mating quality Of the gas furnished the city
can and shall be Temedied promptly-not in
Que locality only, but throughout the extent
of our mains. It must be Understood, how
ever, We cannot and do not undertake 10 make
gas hoW through pipes nlled with scale or rust.
