Other articles where Multistage separation is discussed: separation and purification: Single-stage versus multistage processes: As shown earlier, ease of separation in equilibrium methods is based on the value of the separation factor, α. When this value is large, separation is easy, requiring little input of work. Thus, if α lies between 100 and 1,000, a single equilibration…

Jun 15, 1998· Because it neglects pressure drop inside the hollow fiber, the model does not yield accurate predictions when the feed has a mole fraction of the more permeable component greater than 0.3–0.5. As a result, the model is not appropriate for the design of multi-stage separation systems in which some permeators have a high feed CO 2 concentration.
Feb 23, 2016· Separation is a key part of most chemical processes, and there is a great variety of techniques to perform separation of compounds based on size, volatility, charge, and many other features. A common technique with which the process engineer should be familiar is distillation, but he or she should also be aware of the other available options.
