the supervision of Richard Z. Flem-
ing OF Chicago, tho owner and in
veutor of the process. Considering
the size OF the plant a record was
made for rapid construction for such
heavy work, especially SO as the
contractors laborcd under tho dis
advantage of freight emhargoes and
slow delivery of material. A vast
amount Of steel ana cement was
used in the construction II being

OF these materials by express in or

requires High Grade Material
These stills are operated at a
| working pressure Of about one hun
dred pounds TO the square inch, and
| owing to this pressure the greatest
care must be exercised In tho con-
structIon and selection OF material.
\ much higher grade Of material
and workmanship must be employed
than ~ the case with ordinary crude
stills operating without pressure.
The conversion OF heavier oils into
gasoline is brought about by the ac-
| uOn Of heat and pressure, the effect
being to supei heat the oil vapor as
1t IS produced Under these condi-
tons OF heat and pressure "a consid-
cradle portion of the heavy OIL va

the lighter gasoline fractions, one of
the properties Of petroleum being
that, when It's Vapor is heated above
! normal boiling temperature, its ma
turo Is altered so that when conden-
sed to liquid it Is invariably chang
ed to an oil OF lower boiling point
and lighter In specific gravity.
BY taking advantage Of these pro-
perties 1t is now possible to convert
"A large part of tho residual oils from
the refineries into the much more
valuable gasoline, and IL is this very

complishes. For this process, IL is

In securing and Installing this

that the Marland company is ex-
pending approximately one million
dollars. and this together with tank
age and other improvements now
