Distillation

The process of distillation is one of the oldest processes known to mankind. It has been practised for hundreds of years with new techniques and equipment constantly being developed. Distillation is used as a method of separating a mixture of liquids as well as for separating mixtures of gases. It is a very important separation method and is used extensively throughout the petroleum and chemical industries. In the oil industry it is used almost to the exclusion of any other method of separation of liquid mixtures. Hence an understanding of the technical princples are extremely useful to all of those involved in distillation operations.

Course Objectives
This two day course will provide the background theoretical principles of the process of distillation and link these to the operation of distillation columns in practice. The objective is to provide an understanding of what takes place in a distillation column and relate this to how it is controlled and operated. This will enable operating personnel to appreciate why the various changes made in operating distilaltion columns result in the products that are obtained

Potential Audience
The course is aimed at technical staff who operate and supervise distillation columns. Hence it is assumed that they already know how to operate and control distillation columns and it is hoped that this short course will help them understand why some of the things happen as they do.
