This includes troubleshooting plant problems and carrying out projects to improve the operation. Chemical engineers are involved in environmental protection through measures to protect air and water from pollution, and with energy conversion processes and conservation. Chemical engineers also engage in research and development. Development consists of the collection of engineering data needed to design and construct better equipment or to modify an entire plant. After obtaining some industrial experience, many chemical engineers work in engineering consulting firms or as independent consultants.
Some chemical engineers work in technical sales for a variety of industries.
Others are involved in patent examination, and so become closely associated with the legal profession. Some become engaged in analysis of industrial hazards and safety. A few enter the field of teaching and research in universities and colleges. Students who enjoy chemistry, physics and mathematics, and who do well in these subjects, should consider a career in chemical engineering. An interest in biology is important for those who wish to specialize in pollution control, waste management or biotechnology.
