Ten greatest achievements of chemical engineering

Selasa, 12 September 06 - oleh : Farida

The Atom, as Large as Life:

Biology, medicine, metallurgy, and power generation have all been revolutionized by chemical engineers’ ability to split the atom and isolate isotopes. Early on facilities such as DuPont's Hanford Chemical Plant used 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 identifying clogged arteries and veins. Similarly biologists gain invaluable insight into the basic mechanisms of life, and archaeologists can accurately date their historical findings.

The Plastic Age:

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

The Human Reactor:

Chemical engineers have long studied complex chemical processes by breaking them up into smaller "unit operations." 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 helped improve clinical care, suggested improvements in diagnostic and therapeutic devices, and led to mechanical wonders such as artificial organs. Medical doctors and chemical engineers continue to work hand in hand to help us live longer fuller lives.

Wonder Drugs for the Masses:

Chemical engineers have been able to take small amounts of antibiotics developed by people such as Sir Arthur Fleming (who discovered penicillin in 1929) and increase their yields several thousand times through mutation and special brewing techniques. Today's low price, high volume, drugs owe their existence to the work of chemical engineers. This ability to bring once scarce materials to all members of society through industrial creativity is a defining characteristic of chemical engineering.

Synthetic Fibers, a Sheep's Best Friend:

From blankets and clothes to beds and pillows, synthetic fibers keep us warm, comfortable, and provide a good night's rest. Synthetic fibers also help reduce the strain on natural sources of cotton and wool, and can be tailored to specific applications. For example; nylon stockings make legs look young and attractive while bullet proof vests keep people out of harm's way.

Liquefied Air, Yes it's Cool:

When air is cooled to very low temperatures (about 320 deg F below zero) it condenses into a liquid. Chemical engineers can then separate out the different components. The purified nitrogen can be used to recover petroleum, freeze food, produce semiconductors, or prevent unwanted reactions while oxygen is used to make steel, smelt copper, weld metals together, and support the lives of patients in hospitals.

The Environment, We All Have to Live Here:

Chemical engineers provide economical answers to clean up yesterday's waste and prevent tomorrow's pollution. Catalytic converters, reformulated gasoline, and smoke stack scrubbers all help keep the world clean. Additionally, chemical engineers help reduce the strain on natural materials through synthetic replacements, more efficient processing, and new 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 certain regions of Asia and Africa where food can sometimes be scarce. Advances in biotechnology also offer the potential to further increase worldwide food production. Finally, chemical engineers are at the forefront of food processing where they help create better tasting and most nutritious foods.

Petrochemicals, "Black Gold, Texas Tea":

Chemical engineers have helped develop processes like catalytic cracking to break down the complex organic molecules found in crude oil into much simpler species. These building blocks are then separated and recombined to form many useful products including: gasoline, lubricating oils, plastics, synthetic rubber, and synthetic fibers. Petroleum processing is therefore recognized as an enabling technology, without which, much of modern life would cease to function.

Running on Synthetic Rubber:

Chemical engineers played a prominent role in developing 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 conveyor belts (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.

fancifull article
Kamis, 12 Januari 12 - oleh : andre
all that you wrote seems like a fancifull materials.

I ask you Mrs. Farida Nur Cahyani, What achievements do you or your institution get in chemical engineering ???

NONE, just old books and boring statements. oghhh....... dissappointed.
