Chemical engineers apply the principles of chemistry
and engineering to solve problems involving the production or use of chemicals,
building a bridge between science and manufacturing. They design equipment and
develop processes for large-scale chemical manufacturing, plan and test methods
of manufacturing the products and treating the by-products, and supervise production.
Chemical engineers work in a variety of manufacturing industries other than
chemical manufacturing, such as producing electronics, photographic equipment,
clothing, and pulp and paper. They also work in the health-care, biotechnology
and business services industries.
The knowledge and duties of chemical engineers overlap
many fields. Chemical engineers apply principles of chemistry, physics, mathematics,
and mechanical and electrical engineering. They frequently specialize in a particular
operation such as oxidation or polymerization. Others specialize in a particular
area, such as pollution control or the production of specific products such
as fertilizers and pesticides, automotive plastics or chlorine bleach. They
must be aware of all aspects of chemicals manufacturing and how it affects the
environment, and the safety of workers and customers. Because chemical engineers
use computer technology to optimize all phases of research and production, they
need to understand how to apply computer skills to process analysis, automated
control systems and statistical quality control.
Job outlook
Chemical engineering graduates may face competition
for jobs as the number of openings in traditional fields is projected to be
lower than the number of graduates. Employment of chemical engineers is projected
to grow more slowly than the average for all occupations though 2010.
Although overall employment in the chemical manufacturing
industry is expected to decline, chemical companies will continue to research
and develop new chemicals and more efficient processes to increase output of
existing chemicals, resulting in some new jobs for chemical engineers. Among
manufacturing industries, specialty chemicals, plastics materials, pharmaceuticals,
biotechnology and electronics may provide the best opportunities. Much of the
projected growth in employment of chemical engineers, however, will be in non-manufacturing
industries, especially services industries such as research and testing services.
Earnings
Chemical engineers held about 33,000 jobs in 2000.
Manufacturing industries employed 73% of all chemical engineers, primarily in
the chemicals, electronics, petroleum refining, paper and related industries.
Most others worked for engineering services, research and testing services or
consulting firms that design chemical plants. Some also worked on a contract
basis for government agencies or as independent consultants.
Median annual earnings of chemical engineers were
$65,960 in 2000.
According to a 2001 salary survey by the National
Association of Colleges and Employers, bachelor's degree candidates in chemical
engineering received starting offers averaging $51,073 a year, master's degree
candidates averaged $57,221, and Ph.D. candidates averaged $75,521.
