I suggest you get copies of Henry Z. Kister’s three books published by McGraw-Hill. They are “Distillation Operation,” (1990); “Distillation Design,” (1992); and “Distillation Troubleshooting,” (2006).
I am sure that if you spend time with these books you will find the answer to a lot of your questions. Kister also has a course that covers the topics of your questions.
Additionally, Fractionation Research, Inc. (FRI) has a film (DVD or VHS) on trays know as Film A, which you can purchase that will answer some of your questions and show you video clips of trays in operation in its 4-foot-diameter test units. Film A costs $400 for non-FRI members. This film is used by FRI’s members and universities as a training film about trays in distillation operation.
Additionally, you can get a 20-second look each at trays, packings and a liquid distributor in action on FRI’s Web site, www.fri.org.

There can be many combinations and varities. But you need to monitor the Neutral alcohol Quality as indicated by Fusel oil zone temperatures in Rectifier column or FOC and loss of ethanol in analyser, Rectifier, Fusel oil if bottoms is with drawn. Also monitor steam usage.
