tally made and only partially still charged full OF
crude petroleum and fire started underit When inc
oil has become heated to about 1902, F. the hghtes.
vaors are generated Yhcpass over and are condensed
into very volatile liquid called gasoline orhght napntn
bearing speco gravity OF from 7So TO S5' Beaume On
the anncaon OF additional heat when the temperature
OF the oil has been raised TO about go or 2iC F. LIQUID
Iess volatile but st sprtuous and containing traces OF
oeaeinous lauids passes over. When, finally the uiS
tlafion has reached point where the percentage OF
spirits Denzoe benzine, or naphtha) Is quite Small anu
the proportion OF oil consequently great uVlSoh
made and from that point onward What comes hoin 'no
still IL collected in tank by ITSELF and called Kerosene,
while all that previously passed over IS kept Dy So anu
called naphtha gasoline, &C. according 70 S specho
gravity 1t has long known that there Is In oil inc
benzole or naphtha small percentage OF OIL Whhe the
product that is cold kerosene contains also h''o
benzole There is no point In the distatoh "noro n
that precedes It Is sprituous, ana all that ioo"S 10
oeaEenous because the heat that eyaporates tne So
limo or naphtha in the still raises the light gravity o
yapors with Them and the light vapors OF both nave
such an exceedingly strong affinity for one another In"
they pass cOmminged.
The whole quantity OF splruous material contained III
crude oil Ia quite small. onefth OF percent
Il very explosive 1t is this which accounts Tor te en
plosveness OF kerosene; while to increase the nIe es
Under tbe nresent method OF manufacture Is TO increase
the expense making it, and decrease the yled Oh on
what the new process proposes to do. and mas areau
occompsbed is as foows 1t has made 70 per cent OF

more than the usual YIELD and 400 above the ordinary
fire test cost OF refining exclusive OF Jno price VI
barrels cents per gallon which svery much Tess tha

rae,o aided by a vacuum pump which exhausts the va
pors as soon as they generated In the st TINS pre-
Fonts any burning OF vapOrs in the old process ana
dspenes largely with the sulphurc acid used In rennl
tbe oil. There ore three cOndensing arrangements
Affixed steam condenser surrounding the pipe eadinH
from the still TO the worm, which protects Tue sun
against outside cold pressure, and makes the cV
densation gradual; the worm tub which rs hlied WIN
water heated TO 1902 Fahrenheit, whence the OIL passes
into an alright receiver which is partially hed WIN
water heated 10 n temperature OF ll5'. Inc NapOrs
which condense 1882 are here by means OF syphOnrun
off and passed through cold water into the distate Ahk
fho yapors which will not cOndense at llb' pass on
through tho vacuum pump and through cold water con
denser into the gasoline tank The resdun Is pure o
free from naphtha and pure gasoline OF very hlgh
