Chemical engineers apply the principles of chemistry to help convert raw materials into useful products. They deal with the design, construction, maintenance and operation of plants and equipment to carry out these procedures. In the oil and gas industry, chemical engineers work to help refine crude oil into useable products such as gasoline and lubricants, and they are also heavily involved in chemical plants and manufacturing operations. Some positions that would require a chemical engineer include process engineer, corrosion engineer and petrochemical engineer, among others.
