Interactive Self-Study Module: Single-Stage Batch Distillation
This module uses screencasts and an interactive simulation to explain single-stage batch distillation. It then provides example problems to allow the user to test themselves. Your retention of material in this module will increase if you write down reasons for your answers to ConcepTests, questions in screencasts, and questions to answer before using the interactive simulation, and you try to solve the example problems before watching the screencast solutions. We suggest using the learning resources in the following order:
- Attempt to answer the multiple-choice ConcepTest and solve the example problem before watching the screencasts or working with the simulations.
- Watch the screencasts that describe single-stage batch distillation and answer the questions within the screencasts.
- Review important equations for single-stage batch distillation.
- Use the interactive simulation to further understand single-stage batch distillation.
- Try to solve the example problems before watching the solutions in the screencasts.
- Answer the ConcepTests.
- Look at the list of key points, but only after you try to list the key points yourself.
- The differences in compositions of liquid and vapor mixtures in equilibrium is the basis for the separation of mixtures by distillation.
- This module is intended for a separations course.
Before studying this module, you should:
After studying this module, you should:
- Understand how the mole fraction of distillate changes with time in a batch distillation.
- Be able to represent a batch distillation of a binary mixture on an x-y diagram.
- Know how to solve the Rayleigh equation for batch distillation.
