## Mass Transfer & Separation

### EK-ES-7

## Engineering Performance Matrix

Mass Transfer & Separation is the science that explains and governs a range of separation processes to include absorption, distillation, humidification and drying, and membrane separations, as well as transport processes in equilibrium. This concept is important to Engineering Literacy as it is the basis on which engineers design equilibrium staged chemical processes and analyze chemical or physical principles of materials in order to select appropriate techniques for mass transfer and separation operations.

## Performance Goal for High School Learners

I can, when appropriate, draw upon the knowledge of Mass Transfer & Separation content, such as (a) molecular diffusions (b) separation systems (c) equilibrium state methods, (d) humidification and drying (e) continuous contact methods and (f) convective mass transfer, to analyze the mechanism of transfer due to difference in concentrations to solve problems in a manner that is analytical, predictive, repeatable, and practical.
