What Would I Do?

Chemical Engineers* apply the principles of chemistry and related sciences to solve problems involving the production or use of chemicals and biochemicals in products, such as detergents, plastics, or petroleum. These Engineers design equipment and processes for large-scale chemical manufacturing, plan and test methods of manufacturing products and treating byproducts, and supervise production. They also develop procedures that are energy-efficient, use renewable raw materials, and reduce pollution and waste. Additionally, Chemical Engineers must be aware of all aspects of chemical manufacturing and how the manufacturing process affects the environment and the safety of workers and consumers. Chemical Engineers work in a variety of industries, such as biotechnology, clothing, energy, food, healthcare, petroleum and coal products manufacturing, and scientific research.

Engineers may specialize in a particular chemical process, such as oxidation or polymerization. Others may use their extensive knowledge of chemical processes to minimize the effects of toxins that have entered into the air, soil, or water. In addition, they may develop chemicals that break down in the environment without having any lasting effects. Chemical Engineers also work on developing safer solvents and substances in products, such as cleaners, inks/toners, paints, and pesticides to lessen or eliminate the effects on human and environmental health.

Some Chemical Engineers research, design, and develop fuel cells to power vehicles, trucks, or generators. They work with renewable resources such as biomass to create fuel for heating homes and powering vehicles. They research and develop new materials and improve cell chemistries for batteries to increase efficiency, decrease size and weight, make them safer, and reduce the environmental impact. They also conduct research on recycling and converting carbon dioxide for use in environmentally friendly products. Other Engineers are re-designing solar cells to collect a higher concentration of energy from the sun.

Tools and Technology

Chemical Engineers use a variety of tools in their job including centrifuges, computers, distillation systems, heat exchangers, mass spectrometers, and wet scrubbers. The technology they use include various types of software, such as computer-aided design (CAD), database query, object-oriented development, office suite, project management, and thermal analysis systems.

Green Economy

Chemical Engineers will play an important role in the emerging green economy. Some will assist with the research and design of energy-efficient systems, such as fuel cells and batteries. Others will work within the renewable energy generation sector developing, designing, and testing products using energy sources, such as solar and biomass. Some Engineers will work with traditional non-renewable sources (oil, coal, gas, and nuclear) that are undergoing green technological changes. Engineers are also involved in environmental protection, such as remediation, air quality, and climate change adaptation.
