1/27/11 Multiphase Systems Almost all chemical processes involve material being transferred from one phase to another Phase-change operations – freezing, melting, evaporation,condensation Seperation and purification separate components of mixtures Often A and B are fed into a system

1/27/11 Multiphase Separation Example – brewing a cup of coffee – hot liquid water and solid coffee beans are contacted Soluble portions of the coffee beans transfer from solid phase to liquid solution Residual solids are removed by filtration

1/27/11 Other separation terms Absorption or Scrubbing removal of undesirable portions of a product gas perhaps through contact with a liquid Distillation – separating two liquids based on a difference in vapor pressure Liquid extraction separates liquids based on differences in solubility

1/27/11 Separation Saturated – when a species transfers from one phase to another and the new phase is holding as much of the species as it can Transfer rates of species to their new phase generally slow as saturation approaches Phase equillibrium concentrations

1/27/11 Phase Diagrams At most temperatures and pressures, a single pure substance exists as either a solid, liquid, or a gas- that is a single phase At a few specific T and P, the substance can exist as two or even three phases simultaneously Phase diagram plot one system variable versus another (usually T

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
