HP Flashback
treating petroleum naphtha continues to be the most widely
used. This article provides the advantages and disadvantages of
treating cracked distillate with sulfuric acid.
Design of treating system includes facilities for purging
January 1933
Preparation of ethyl alcohol from ethylene
V. Gerr, O. Pipik and E. Mezhebovskaya, February 1933
In this series of articles, information is presented dealing
with the preparation of ethyl alcohol from petroleum gases
both in the laboratory and in commercial scale. Ethylene was
separated from the homologs by making use of the selective
absorption ability of activated charcoal and separated in the
form of ethyl sulfuric acid and the alcohol separated by hydrolysis.
Silver and iron catalysts were used to accelerate the
reaction. The constants of the synthetic alcohol coincide with
those of fermentation alcohol.
Meeting some of the problems of the
pressure vessel user
T. McL. Jasper, O. E. Andrus and L. J. Larson, April 1933
The history of pressure vessel development can be characterized
by a series of increasing demands by the pressure vessel
user, which have been met by the pressure vessel manufacturer.
The invention of the steam engine marks the starting point
in the demand for pressure equipment on a quantity basis. This
demand started on a relatively small scale and has expanded
into the use of large quantities of steel and other materials.
Many different methods of factrication have been used for producing
pressure vessels. Cast iron, bolted and riveted wrought
materials, forge welded cylinders, solid forgings and, most recently,
autogenous welded vessels have marked the general history
of the development.
Tube wall telescope for examination of interior
of tubes and piping
May 1933
This article details an invention that enables plant personnel
to examine the inside of tubes and piping.
Development of naphtha reforming practice
for octane number improvement
E. J. LeRoi and H. W. Ferguson, June 1933
Naphtha reforming is a direct outgrowth of the ever-increasing
demand for higher octane number motor fuels. Since the refiner
has been dependent in the past on selection of crudes and
blending fluids for anti-knock improvement, the application
of naphtha cracking lends greater flexibility to refinery operations.
This article details three years of experimental work on
both straight-run and cracked heavy naphtha. The combined
and individual effects of time, temperature and type of feedstock
on yield, capacity and product quality have been carefully
analyzed for varying degrees of octane number improvement.
Removal of hydrogen sulfide from high-sulfur gases
P. J. Wilson, July 1933
This article details three new processes-developed in the
past year-to remove hydrogen sulfide from high-sulfur gases.

Comparison of cracking and hydrogenation as
methods of producing gasoline
R. T. Haslam, R. P. Russell and W. C. Asbury, September 1933
This article focuses exclusively on the use of the hydrogenation
process for gasoline production from gasoil. A critical analysis
has been made of the factors which affect the economic position
of the hydrogenation process, the ability of the process to
compete with cracking and its use in conjunction with cracking.
Automatic temperature control in oil refining
V. R. Chadbourne and P. E. Darling, December 1933
Deviations from optimum operational conditions result in
decreased yields, shortened runs and a departure from the desired
product specifications. Modern refining units have variables
such as flow, furnace temperatures, outlet temperatures
and tower levels held within very close limits by automatic devices.
Any control that will increase the yield by a fraction of
one percent, even though of high initial cost, will be paid for by
the increased yield in a remarkedly short time.
Design of high-pressure rectifiers
I. N. Beall, March 1934
This series of articles focuses on high-pressure rectifiers that
are in use for the stabilization of natural gasoline.
Regular grade cracked gasoline and " Q " grade ethyl
compared
W. Hubner and G. B. Murphy, May 1934
While the octane number method of rating gasoline quality
has become generally reconfirmed and accepted by the automobile
and oil industries, doubts have been growing in the minds of
many technologists as to the adequacy of this method as the only
criterion on which to measure the value and base the price of
motor fuel. Because of these doubts, road and laboratory dynamometer
tests were made in which the performance of cracked
gasoline from one refinery, undoped, was compared against " Q "
grade gasoline of equal volatility and equal octane rating.
The tests showed that there are desirable performance properties
not shown by octane number tests, primarily miles per
gallon and horsepower hours per gallon. Conclusions drawn
from the road and laboratory tests showed non-ethylized regular-grade
cracked gasoline is a motor fuel superior to " Q " grade
ethyl of equal volatility and equal octane number rating.
Fouling of heat exchangers
W. L. Nelson, July 1934
These articles focus on the fouling of heat exchangers and
the fouling factors which are obtained in classes of heat transfer
equipment. Part 1 provides an introductory to heat transfer and
fouling, with Part 2 focusing on fouling factors that can be expected
in plant service, the deposition of coke in pipe still tubes,
the temperatures that are attained in pipe still tubes and the
fouling conditions caused by hard water and wax.
Prospects of a petroleum chemical industry
C. Ellis, September 1934
During recent years, there has been a steady trend toward
the establishment of a chemical industry dependent upon petroleum
as a source of raw material.
