Chemical engineers typically do the following:
- Conduct research to develop new and improved manufacturing processes
- Establish safety procedures for those working with dangerous chemicals
- Develop processes for separating components of liquids and gases, or for generating electrical currents, by using controlled chemical processes
- Design and plan the layout of equipment
- Conduct tests and monitor the performance of processes throughout production
- Troubleshoot problems with manufacturing processes
- Evaluate equipment and processes to ensure compliance with safety and environmental regulations
- Estimate production costs for management
Some chemical engineers, known as process engineers, specialize in a particular process, such as oxidation (a reaction of oxygen with chemicals to make other chemicals) or polymerization (making plastics and resins).
Others specialize in a particular field, such as nanomaterials (extremely small substances) or biological engineering. Still others specialize in developing specific products.
In addition, chemical engineers work in the production of energy, electronics, food, clothing, and paper. They must understand how the manufacturing process affects the environment and the safety of workers and consumers.
Chemical engineers also conduct research in the life sciences, biotechnology, and business services.

- Consequence of Error (73%)
- Exposed to Contaminants (38%)
- Hazardous Conditions (37%)
- Time Pressure (36%)
Chemical engineers must have a bachelor’s degree in chemical engineering or a related field. Programs in chemical engineering usually take 4 years to complete and include classroom, laboratory, and field studies. High school students interested in studying chemical engineering will benefit from taking science courses, such as chemistry, physics, and biology. They also should take math courses, including algebra, trigonometry, and calculus.
At some universities, students can opt to enroll in 5-year engineering programs that lead to both a bachelor’s degree and a master’s degree. A graduate degree, which may include a degree up to the Ph.D. level, allows an engineer to work in research and development or as a postsecondary teacher.
Some colleges and universities offer internships and/or cooperative programs in partnership with industry. In these programs, students gain practical experience while completing their education.
ABET accredits engineering programs. ABET-accredited programs in chemical engineering include courses in chemistry, physics, and biology. These programs also include applying the sciences to the design, analysis, and control of chemical, physical, and biological processes.
Licensure for chemical engineers is not as common as it is for other engineering occupations, nor is it required for entry-level positions. A Professional Engineering (PE) license, which allows for higher levels of leadership and independence, can be acquired later in one’s career. Licensed engineers are called professional engineers (PEs). A PE can oversee the work of other engineers, sign off on projects, and provide services directly to the public. State licensure generally requires
- A degree from an ABET-accredited engineering program
- A passing score on the Fundamentals of Engineering (FE) exam
- Relevant work experience, typically at least 4 years
- A passing score on the Professional Engineering (PE) exam
The initial FE exam can be taken after one earns a bachelor’s degree. Engineers who pass this exam are commonly called engineers in training (EITs) or engineer interns (EIs). After meeting work experience requirements, EITs and EIs can take the second exam, called the Principles and Practice of Engineering (PE).
Each state issues its own licenses. Most states recognize licensure from other states, as long as the licensing state’s requirements meet or exceed their own licensure requirements. Several states require engineers to take continuing education to keep their licenses.
