HP Flashback
World demand expands faster
R. S. Spann, January 1955
Global petroleum demand is expected to reach more than 14
MMbpd in 1955, an increase of about 6.6% vs. 1954.
Turnaround scheduling
J. O. Thoen, March 1955
Allowable run length, worker availability and process commitments
all play major roles in turnaround scheduling.
Carbon formation in cat cracking
P. B. Crawford and W. A. Cunningham, January 1956
This article details a method to estimate the effect of charging
rate, process period and temperature on the quantity of
carbon deposited on the catalyst in a catalytic cracking unit.
In addition, a path is provided to use fixed-bed reactor data for
estimating results with the same catalyst and charge in moving
bed or turbulent fluidized reactors.
What causes hydrogen attack?
G. R. King, March 1956
Hydrogen attack takes many forms. Some of these are more
serious than others. This article will help plant personnel recognize
the various forms of hydrogen attack and plan the most
economical maintenance program.
How to select the right pump motor
October 1956
Do you know when to use the normal inrush and when to
use the low inrush motor? This comparison between speedtorque
characteristics of pump and motor will help you decide.
Is your distillation column in balance?
W. D. Harbert, November 1956
The operation of a distillation column is more costly if it is
not in balance. This article provides a non-mathematical discussion
of column balance and how to achieve it.
Analog computers calculate heat transfer
R. S. Schechter, February 1957
The increased availability of computing devices has caused
considerable interest in expanding the scope of problems which
are adaptable to automatic computation. The purpose of this
article is to point out the usefulness of the analog computer in
solution of natural convection problems.
Future fields of elastomers
J. Bjorksten, March 1957
The outlook for elastomers is exceptionally bright because
of low fabrication costs.
Here is data on propane fractionation
E. E. Smith and C. E. Fleming, July 1957
Some of the advantages of separating hydrocarbons according
to their solubility in liquid propane are discussed in this article.
These data are compared with separation by distillation.
What to do about corroding isomerization units
J. F. Mason and C. M. Schillmoller, July 1958
62 SEPTEMBER 2022 | HydrocarbonProcessing.com
Even though the process aspects of butane isomerization
have been discussed in several articles in recent years, little has
been said about the corrosion problems associate with these
units. The intention of this article is to review some of these
problems and point out where corrosion has occurred or can
normally be expected to occur, so that this information may
serve as a guide to those who have butane isomerization units
in the design or planning stage.
Urea-The petrochemical to watch
L. F. Hatch, August 1958
Urea is one of the fastest growing petrochemicals, with a 270%
production increase in 8 yr. It is a triple-threat petrochemical with
a dynamic future for fertilizer, animal feeds and synthetic resins.
Alkylation-What you should know about this process
R. E. Payne, September 1958
This comprehensive article tells of the many factors that influenced
the alkylation process and its products. It will focus on
the commercial aspects of alkylation-plant designs, operating
techniques and process variables. The article will also provide
details regarding investment and operating costs, some octane
blending data and process history.
A checklist for plant layout
J. F. McGarry, October 1958
Whether it is a refinery or petrochemical plant, the article
provides tips that will help attain maximum flexibility and compactness
at a reasonable initial cost.
Petroleum Refiner: The Oil Centennial Issue
January 1959
This issue of the Petroleum Refiner provided a detailed look at
the past 100 yr of the oil industry. This included the history of
refining and petrochemical discoveries and technologies, as well
as a look at the current global demand for petroleum products.
Find the best air fin cooler design
E. U. Nakayama, April 1959
Plant personnel must compare investment costs with operating
costs to come up with the best cooler design. This article
provides a sample problem that details this notion in action.
Which acetylene removal scheme is better?
W. H. Stanton, May 1959
Which method of acetylene removal-absorption or hydrogenation-is
the most economical? One method is economically
superior to the other depending upon the following variables:
plant size, byproduct value of acetylene and acetylene
made per 100 lbs of ethylene produced. This article provides
the economics of absorption vs. hydrogenation for removing
acetylene from rich ethylene streams.
