Effects Of The Number Of Trays Or Stages

Feed Tray Distillation Column

Here we will expand on the design of columns by looking briefly at the effects of p the number of trays, and p the position of the feed tray, and on the performances of distillation columns. Effects of the Number of Trays It can be deduced from the previous section on distillation column design that the number of trays will influence the degree of separation. This is illustrated by the following example. - Consider as a base case, a 10 stage column. The feed is a binary mixture that has a...

Factors Affecting Distillation Column Operation

Heat Balance Distallation Columns

The performance of a distillation column is determined by many factors, for example trace elements that can severely affect the VLE of liquid mixtures.-- 'p internal liquid and fluid flow conditions 'p state of trays packings weather conditions Some of these will be discussed below to give an idea of the complexity of the distillation process. The state of the feed mixture and feed composition affects the operating lines and hence the number of stages required for separation. It also affects...

Column Reboilers

Distillaton Column Design Procedure

There are a number of designs of reboilers. It is beyond the scope of this set of introductory notes to delve into their design principles. However, they can be regarded as heat-exchangers that are required to transfer enough energy to bring the liquid at the bottom of the column to boiling boint. The following are examples of typical reboiler types.

Distillation Basics

Main Components of Distillation Columns Distillation columns are made up of several components, each of which is used either to tranfer heat energy or enhance materail transfer. A typical distillation contains several major components p a vertical shell where the separation of liquid components is carried out p column internals such as trays plates and or packings which are used to enhance component separations p a reboiler to provide the necessary vaporisation for the distillation process p a...

Costello and Associates, Iiil. Fur distillation design and troubleshqatlng Effects of the Number of Trays or Stages a process in which a liquid or vapour mixture of two or more substances is separated into its component fractions of desired purity, by the application and removal of heat. Distillation is based on the fact that the vapour of a boiling mixture will be richer in the components that have lower boiling points. Therefore, when this vapour is cooled and condensed, the...
