## What do you learn in Separation Processes

Separation Processes covers techniques for separating mixtures in chemical engineering. You'll learn about distillation, absorption, extraction, and membrane separations. The course dives into mass transfer principles, equilibrium stages, and continuous contacting operations. You'll also explore the design and analysis of separation equipment like distillation columns, absorbers, and extractors.

## Is Separation Processes hard?

Separation Processes can be challenging, but it's not impossible. The math can get pretty intense, especially when dealing with multi-component systems and complex equilibrium calculations. The concepts aren't too bad, but applying them to real-world problems can be tricky. Most students find it manageable with consistent effort and practice.
