The age of planetary exploration has revealed that meteor
impact is a fundamental process in the evolution of planets,
and the discovery of evidence that a large meteor impact may
have triggered the extinction of the dinosaurs has raised
awareness of the role of impact on the earth. Several times a
year the earth is struck by objects packing the energy of a
small nuclear weapon. These objects break up in the
atmosphere and are seen as brilliant fireballs. Fragments often
survive to reach the surface as meteorites. Perhaps once a
century objects hit the surface hard enough to dig small
craters, and once every few thousand years objects with megaton energies, capable of
making kilometer sized craters, strike the earth. Much larger impacts are possible. The
physics of large impacts is simply astounding. The forces involved are so far beyond the
yield strength of rock that the rock behaves as if it has no strength at all, and some of the
best analogs of cratering mechanics are slow-motion photographs of droplets splashing.
The kinetic energy of the impacting object converts instantaneously into heat, and the
impacting object and large amounts of target material are melted and vaporized. The
resulting crater is about 30 times the diameter of the impacting object. Multi-kilometer
meteors can have global effects. Radiant heat and blast effects can cause damage for

hundreds of kilometers, and the impact fireball can create vast quantities of nitrogen
oxides. Ejecta blasted into space can subject the entire earth to intense radiant heat.
Stratospheric dust can block sunlight and volatiles liberated from the target rocks can
have important climatic effects. As one impact researcher put it: "The problem isn't
figuring out how a large impact can cause a mass extinction. It's figuring out how
anything survives." This talk can be presented at a popular level for general audiences or
at a moderately technical level for audiences comfortable with back of the envelope

Brief Bio
Steven Dutch is a geologist who got his bachelor's degree (and a ringside seat for the
unrest of the 1960s) from the University of California at Berkeley. He did his doctoral
research at Columbia University, with a break for military service that included a year in
Turkey. The subject of his thesis was the geology of the Sudbury, Ontario area, but in
1975, he also participated in a Columbia expedition to Antarctica. Since 1976, he has
been at the University of Wisconsin at Green Bay, where he holds the rank of professor
and teaches "hard rock" geology: mineralogy, petrology, structural geology, and plate
tectonics. His principal research interests are the Precambrian geology of the Great Lakes
region, the development of computer programs for earth science education, and the
relationships between science and society, particularly as expressed in pseudoscience
movements. He is the author of an earth science textbook. In 1982, Dr. Dutch resumed
his military career by joining the 432nd Civil Affairs Battalion of the U.S. Army Reserve.
He spent six months in the Persian Gulf and Kurdistan in 1991 and six months with the
peacekeeping mission in Bosnia in 1996, and retired from the military in 2001.

Why Do I Belong to AIChE?
Why would a chemical engineer want to pay the national dues to be a
member of AIChE? People often answer this question with a laundry
list that includes access to publications, online resources, insurance,
discounts, etc. These are good reasons, but for me, there are two more
important reasons I have been an AIChE member for 25 years:
       AIChE has supported, shaped, and been an advocate for my
        profession and is worthy of my support.
       I want to participate in my profession to enhance my own career.
So how does AIChE support, shape, and promote chemical engineering? Here are a few
    The ABET accreditation program for chemical engineering departments is a direct
      outgrowth of AIChE's pioneering efforts in the 1930s.
    AIChE meetings and publications have continued to define and carve out a
      profession with enormous impact distinct from industrial chemistry.
    The advocacy efforts to influence government policy give my profession a voice.
4                                                                           The Pipeline
     Its research initiatives directly address important needs, such as safety and physical
      properties, that are common to industrial companies.
The second reason I support AIChE is that I want to go beyond my employer to improve
my career through opportunities to learn, grow, lead, contribute, and connect with others.
The local section offers ample opportunities for this as well as the national organization.
Consider the following: "A recent survey of hiring managers and
headhunters revealed that a whopping 79% see job applicants who are involved with
professional associates as "high quality candidates" than those who aren't." –as quoted by
Annie Fisher, Fortune Magazine, Feb. 22, 2005.

The national dues that I pay are such a tiny sum compared to my salary that it is an easy
decision for me to participate in AIChE, my chemical engineering professional

I hope you will consider joining if you are not already a member, and spread the word
among others about the critical importance of the Institute to the development of
chemical engineering, our communities of practice, and our own careers.

2008 East Tennessee Section Chair

                        Report on January Meeting
 The Sipchem Jubail Acetyl Complex (JAC), an Eastman Acetyl Licensing Project
Presented by Ty Earls, Principal Chemical Engineer, Eastman Chemical Company

Our January 2008 local section program was attended by more than 100 people in the
Eastman Research Auditorium in Kingsport.

Eastman, a chemical company in headquartered Kingsport, Tennessee with 11,000
employees and $7 billion in sales revenue, was approached in 2002 by Sipchem who was
interested in obtaining technology to construct an acetyls complex in Jubail, Saudi
Arabia. Sipchem is "Saudi International Petrochemical Company," founded in 1999.
Sipchem currently has a new 1 million metric ton / year methanol plant, a tetrahydrofuran
/ butanediol plant, and is currently constructing the acetyl complex based on Eastman
technology. In addition, engineering has begun for a large olefins and derivatives
complex. All these facilities are in Saudi Arabia.
5                                                                         The Pipeline
Eastman agreed to supply acetyls technology. The technology is a variation of that
Eastman has developed for its own use, but re-optimized to produce primarily acetic acid
rather than acetic anhydride. Eastman provided a complete basic engineering package in
2005. The plant will produce acetyls via methyl acetate carbonylation using carbon
monoxide and methanol "across the fence" from Sipchem's natural gas steam reforming
plant. The primary market for acetic acid will be to produce vinyl acetate monomer.
Eastman will market all the acetic anhydride produced. The Jubail Acetyl Complex
(JAC) will include a 340K metric ton/yr CO facility, 460KMT/y acetyl plant (Eastman),
300KMT/y VAM plant (DuPont), plus utilities and port facilities.

The entire complex is motivated by Saudi Arabia's desire to reinvest oil income into
higher value products to provide jobs for a rapidly-expanding population. The raw
material is natural gas, most of which would otherwise be flared as it is "stranded" from
suitable markets. The location in Jubail, which is on the Persian Gulf, is convenient for
bulk shipping of the commodity products. Jubail itself is an ancient fishing village which
has been transformed by huge investments in a new "industrial city." The sea water used
for cooling is the warmest in the world, and is cooled in a lengthy man-made canal.
Unfortunately, the weather gets cold enough in the winter to still require heat tracing to
prevent freezing of acetic acid. Summertime temperature peak near 50 degrees C, or 122

The layout of the industrial city is shown below. The JAC is located in the lower right
corner of the purple industrial area shown below.

The execution of the project presented many challenges. The basic engineering package
was created by Eastman in Kingsport, Tennessee. The detailed engineering and hazard
reviews were conducted by contractors in Reading, England and in Calgary, Alberta,
Canada. Further work was done in Greenville, South Carolina. The Eastman engineers
had to travel the world to conduct the design and reviews with Sipchem, Foster Wheeler,
and Fluor. Engineering design had to be applied to 400 pieces of equipment, and 200
P&IDs. The chemical hazards and highly corrosion resistant alloys caused the
technology to be covered under U.S. Export Control laws, which of course was another
challenge. Operators for the plant are being trained by Eastman in Kingsport, Tennessee.
Eastman will also provide commissioning and start-up support.

Even though the project was difficult because of culture and geography, Eastman
engineers and others have gained enormously valuable experience, extra pay, and some
good stories! Eastman Chemical Company will gain licensing revenues, and have a
source of acetic anhydride in the Middle East to sell to expanding markets.

Thanks, Ty, for sharing a fascinating story of chemical engineering in our globalized
world! Below is Ty in a different style of clothing than he was used to from his native

                                    March, 2008

What: 2008 Egg Drop Contest, Call for Volunteers

When: Saturday, March 8th 2008, 1:00pm -3:00pm

Where: Fort Henry Mall, Belk Court--Kingsport, TN

RSVP: Lauren Moyer email:

March 8, 2008 the Holston Section of ASME and other professional organizations and
community partners are once again bringing to our community the world famous Egg
Drop Contest. Designed to promote engineering and science in the Tri-Cities community,
it's also an excellent opportunity to encourage students to consider math, science, and
other technical fields/disciplines as career options.
8                                                                          The Pipeline

The Egg Drop contest encourages local students to put their math and science skills to
work in a fun and challenging way as they design protective cases for eggs, and then drop
the eggs from 22 feet onto a target. Contestants earn points based on how many parts
their cases comprise, how close to the target the egg lands (and, of course, whether the
egg lands safely), and how much the case weighs. The top three winners in each of 5
categories will be receiving cash prizes.

Last year was a tremendous success with over 100 participants. Participants vary in age
from child to adult and participants can participate as a single entrant or as a team.

The event will be held in the Fort Henry Mall in Kingsport, TN at 1PM on Saturday
March8, 2008.

At this point we need several volunteers to help prepare for the event and during the day
of the event. This will include gathering supplies before the event, registration and many
other activities during the event. If you want to help with this incredible outreach please
contact Lauren Moyer at
