A series of open-ended laboratory projects illustrate the principles of unit operations and process control. Experiments are designed to be relevant to current industrial, environmental, and safety practices. Examples include distilling mixtures, such as ethanol and water; removing pollutants from stack gasses; controlling pH in tank systems with flow; testing mixture explosion properties; operating liquid-liquid extraction systems, such as ethanol and water; designing reactors based on the reaction kinetics of ethane hydrogenolysis; and separating oxygen and nitrogen in air using a hollow-fiber membrane. Oral and written reports are required.
