So What Exactly Does This
"Universal Engineer" Do?During the past Century, chemical engineershave made tremendous contributions to our
standard of living. To celebrate theseaccomplishments, the American Institute ofChemical Engineers (AIChE) has compiled a list
of the " 10 Greatest Achievements of ChemicalEngineering. " These triumphs are summarized
below:

The Atom :
Biology, medicine, metallurgy, and power generationhave all been revolutionized by our ability to split the
atom and isolate isotopes . Chemical engineers played
a prominent role in achieving both of these results. Earlyon facilities such as DuPont's Hanford Chemical Plantused these techniques to bring an abrupt conclusion to
World War II with the production of the atomic bomb.Today these technologies have found uses in more
peaceful applications. Medical doctors now use
isotopes to monitor bodily functions; quickly identifyingclogged arteries and veins. Similarly biologists gaininvaluable insight into the basic mechanisms of life, and
archaeologists can accurately date their historicalfindings.

The Plastic Age:The 19th Century saw enormous advances in polymer
chemistry . However, it required the insights of chemicalengineers during the 20th Century to make mass
produced polymers a viable economic reality . When aplastic called Bakelite was introduced in 1908 it sparked
the dawn of the "Plastic Age" and quickly found uses inelectric insulation, plugs & sockets, clock bases, iron
cooking handles, and fashionable jewelry. Today plastichas become so common that we hardly notice it exists.
Yet nearly all aspects of modern life are positively andprofoundly impacted by plastic.

The Human Reactor:Chemical engineers have long studied complex chemical
processes by breaking them up into smaller " unitoperations. " Such operations might consist of heat
exchangers, filters, chemical reactors and the like.Fortunately this concept has also been applied to the
human body. The results of such analysis have helpedimprove clinical care , suggested improvements in
diagnostic and therapeutic devices , and led tomechanical wonders such as artif icial organs . Medical
doctors and chemical engineers continue to work hand inhand to help us live longer fuller lives .

Wonder Drugs :
Chemical engineers have been able to takesmall amounts of antibiotics developed by
people such as Sir Arthur Fleming (whodiscovered penicillin in 1929) and increase theiryields several thousand times through mutation
and special brewing techniques. Today's lowprice, high volume, drugs owe their existence
to the work of chemical engineers. This ability tobring once scarce materials to all members of
society through industrial creativity is a definingcharacteristic of chemical engineering

Synthetic Fibers :
From blankets and clothes to beds andpillows, synthetic fibers keep us warm ,
comfortable , and provide a good night'srest . Synthetic fibers also help reduce the
strain on natural sources of cotton andwool , and can be tailored to specific
applications. For example; nylonstockings make legs look young and
attractive while bullet proof vests keeppeople out of harm's way.

The Environment,
We All Have to Live Here:Chemical engineers provide economical answers
to clean up yesterday's waste and preventtomorrow's pollution . Catalytic converters ,
reformulated gasoline , and smoke stackscrubbers all help keep the world clean.
Additionally, chemical engineers help reduce thestrain on natural materials through synthetic
replacements , more efficient processing , andnew recycling technologies.

Food, " It's What's For Dinner" :
Plants need large amounts of nitrogen , potassium ,and phosphorus to grow in abundance. Chemical
fertilizers can help provide these nutrients to crops,which in turn provide us with a bountiful and balanced
diet . Fertilizers are especially important in certainregions of Asia and Africa where food can sometimes be
scarce . Advances in biotechnology also offer thepotential to further increase worldwide food production.
Finally, chemical engineers are at the forefront of foodprocessing where they help create better tasting andmost nutritious foods.

Petrochemicals,
" Black Gold, Texas Tea" :Chemical engineers have helped develop
processes like catalytic cracking to breakdown the complex organic molecules found in
crude oil into much simpler species. Thesebuilding blocks are then separated and
recombined to form many useful productsincluding: gasoline , lubricating oils , plastics ,
synthetic rubber , and synthetic fibers .Petroleum processing is therefore recognized asan enabling technology , without which, much
of modern life would cease to function

Running on Synthetic Rubber:
Chemical engineers played a prominent role indeveloping today's synthetic rubber industry.
During World War II , synthetic rubber capacity
suddenly became of paramount importance.This was because modern society runs on
rubber. Tires , gaskets , hoses , and conveyorbelts (not to mention running shoes ) are all
made of rubber. Whether you drive, bike, roller-blade, or run; odds are you are running on
rubber.
