Excerpts from the 1970s: Maintenance,
optimization, safety and digital technologies
You can predict turbomachinery reliability
J. S. Sohre, January 1970
Reliability factor curves have been drawn as a guide to
probable trouble in components or entire turbomachinery
systems. Designers can use reliability factors to upgrade weak
system components. Maintenance can use the factors to pinpoint
probable trouble areas.
Low-sulfur fuels are different
C. W. Siegmund, February 1970
A change to low-sulfur fuel oils can change the requirements
for storing and pumping these fuels. Fuels from lowsulfur
crudes will have a higher viscosity, while desulfurization
of high-sulfur stocks will produce lower viscosity but
higher costs.
What's ahead for aromatics?
S. Field, May 1970
In this decade (1970s), chemicals will require 230,000 bpd
and gasoline 1 MMbpd of aromatics. Refiners will face new
problems in butene, xylene and toluene production, conversion,
processing and extraction to meet this demand.
Refiners face challenges of 1970s
J. D. Wall, December 1970
Challenges facing the refining industry will cause shifts in
locations of refining centers, product distributions and processing
styles. Changes will take place to accommodate growing
demand for more consumer products and chemical feeds.
The needs are clear. The solutions are less clear.
A bigger role for cat reforming
H. L. Hoffman, February 1971
Catalytic reforming of naphthas to produce aromatics is
growing at an accelerated pace. The HPI looks to this process
for aromatics to improve antiknock ratings of motor fuels and
to furnish feeds for petrochemicals.
Optimize olefin cracking coils
J. L. de Blieck and A. G. Goossens,
March 1971
Based on simple kinetics and extensive pilot and commercial
plant operations, the radiant cracking coils can be optimized
for product pattern and investment.

Natural gas grows in world use
J. Salkeld, April 1971
The U.S. and the USSR have long dominated the use of
natural gas. Now, with better pipelines and LNG, gas is on the
move. It is becoming a bigger factor in the energy picture of
most world areas. The article examines what can be expected
in the judgment of an authoritative market analyst.
Synthetic fiber feedstocks
P. Leprince, July 1971
Synthetic fibers-nylons, polyesters, acrylics and polyolefins-show
growth rates above 10%/yr. With this fiber
growth and its increasing demand on HPI feedstocks, present
data indicates ample raw material supplies with minimum
supply-demand dislocations.
How styrene grows in Europe
July 1971
From 500 MMlb of styrene converted into plastics in 1960,
markets have grown to about 2.5 Blb today. A future annual
growth rate for styrene monomer of 10%-12% is expected.
Flue gas desulfurization technology
A. B. Welty, Jr., October 1971
How do we keep sulfur out of the air? Flue gas desulfurization
is one way that many are considering, and a few are trying.
This article is an analysis of the possibilities for making this approach
work. It is " must reading " if you have a flue gas problem.
Wastewater treatment
M. R. Beychok, December 1971
Stronger laws and tougher enforcement make design of the
wastewater treatment system more important, but state-of-theart
processes can meet the challenge when properly used by
the design engineer.
Better gasoline chromatography
H. Boer and P. van Arkel, February 1972
Multistage chromatography is used to determine the paraffin-naphthene-aromatic
composition of products in the naphtha
boiling range.
Optimize the ethylene complex
A. J. Gambro, K. Muenz and M. Abrahams, March 1972
