Knowra Chemical engineer Chemical engineer A chemical engineer applies chemistry, physics, biology, and mathematics to design and operate processes that transform raw materials into useful products.
Petroleum refining : The industrial separation and conversion of crude oil into fuels, lubricants, and chemical feedstocks. Refineries use process design, reaction engineering, and separation methods central to chemical engineering.
Chemical reaction engineering : The study of reaction rates and reactor design for carrying out chemical transformations. It links reaction chemistry to the reactors chemical engineers specify and operate.
Material balance : An accounting equation that tracks the amounts of materials entering, leaving, and accumulating in a system. Material balances establish how much feed, product, and waste a process produces.
Mechanical engineer : An engineer who designs, analyzes, and maintains machines and mechanical systems. Mechanical engineers focus more on machines and mechanical components than on transforming process streams.
George E. Davis : A British chemical engineer whose lectures helped establish chemical engineering as a distinct profession. His 1887 lectures presented a systematic account of industrial chemical processes.
Pharmaceutical manufacturing : The development and production of medicines under controlled quality and safety requirements. Chemical engineers scale drug-making processes while preserving product quality and consistency.
Transport phenomena : The study of momentum, heat, and mass transfer in physical systems. These transfers determine how materials and energy move through equipment and affect process performance.
Energy balance : An accounting equation for energy entering, leaving, and accumulating in a system. Energy balances reveal heating, cooling, and power requirements across process equipment.
Electrical engineer : An engineer who designs and analyzes electrical and electronic systems. Electrical engineers center their work on circuits, power, and signals rather than material conversion.
Margaret Hutchinson Rousseau : An American chemical engineer known for designing large-scale penicillin production processes during World War II. Her work demonstrated how chemical engineers could transform pharmaceutical production at scale.
