Chemical engineering and chemistry

The strong technical and social ties that bind chemistry and chemical engineering are unique in the fields of science and technology.

The alliance between chemists and chemical engineers has been beneficial to both sides and has rightfully brought the contribution to the other engineering fields.

How does chemical engineering differ from chemistry? Chemists discover the chemical reactions by which useful products may be made. Chemical engineers combine the science of chemistry with the discipline of engineering in order to manufacture materials and products essential to modern society. They are involved with the full scale of processes from the laboratory bench to the pilot plant and eventually at the manufacturing facility.

Chemical engineers discover the processes and develop the equipment that allows the chemical reactions to work economically. The academic training of chemical engineers provides a strong background for a variety of areas, including process design, production engineering, research and development, safety, marketing/technical sales, environmental and waste management.

Chemical engineering is particularly adaptable to solving the technological problems of modern society. Therefore, chemical engineers are often employed by the government and industrial firms. They make invaluable contributions to an improved quality of life by producing pharmaceutical products to cure diseases, fertilizers and pesticides to help feed a growing population, fabrics to clothe us, and petroleum products to warm our houses and move our cars. Chemical engineers also are deeply involved in preventing and treating pollution.

In addition to these key areas, chemical engineers are actively developing advanced materials used in the communications and space industries, food and beverage industries, and modern electronics. Chemical engineers are actively involved in developing improved polymer processing and devices relevant to biomedical engineering. Another important research area is the physical and biological treatment of hazardous wastes.

Other exciting frontier areas of research in chemical engineering include molecular and nanoscale engineering, molecular simulation, surface modification, protein separation processes, supercritical fluid extraction, fluid particle systems, catalysis and reaction engineering, biochemical engineering, and computer-aided design.
