Introduction to fluid separations processes used in a variety of industries, such as (petro)chemical, (bio)pharmaceutical, carbon capture, water treatment and desalination, and mining and metals. The course will describe fundamentals of unit operations that comprise these separation processes. Staged-equilibrium processes such as distillation, absorption, and extraction will be discussed. Other unit operations that will be covered include membrane separations, adsorption, chromatography, ion exchange, crystallization, sedimentation, and centrifugation. Energy efficiency and minimum energy of separations will be discussed. Process modeling software will be introduced.
