Some chemical engineers become astronauts, computer system designers, or brewers of specialty beers. They may come up with a new material or a better way to produce an existing products. The mass production of antibiotics, for example, was made possible by chemical engineers in research. Chemists invented the many synthetic fibers we use today, but chemical engineers designed the plants that produce them at an affordable cost. Production engineers are always answering such questions.
Sales engineers answer such questions.
People skills, as well as technical ability, are very important for these chemical engineers. While less involved in technology, they make policy and business decisions, train new engineers, and solve human, rather than technical, problems. This list is neither complete nor comprehensive. For instance, some chemical engineers work in hospitals to find the best method of administering a particular drug to a patient. There is no limit to the kinds of challenging work chemicals engineers do.
