How can you estimate the release of pollutants from a coal-fired power plant and how changes to processes within the plant might influence the amount released to the environment? If a drug compound synthesized in the laboratory on small scales is showing promising results, how do you start to think about producing enough to treat millions of people? Chemical engineers are challenged with similar questions across a wide variety of fields and applications, including petroleum refining, pharmaceuticals, polymers, consumer products, water purification, food science, and commodity and specialty chemicals. In designing the processes to support these various needs, chemical engineers consider the operations involved, the required amounts of raw materials, separations of more and less valuable materials, environmental impact, and energy requirements. In this course you will be introduced to methods chemical engineers use to evaluate and estimate the components of a chemical process. The decisions related to chemical processes can have profound economic, medical, environmental, and even political consequences.
