Do not try blindly specs and number of trays. it won’t work most of the time.2. If you have many components do not include them all at the beginning. start with afew of the most abundant components.3. Put an adiabatic flash first. if the feed is not two phase at the desired pressure,use an isothermal flash. Change the temperature until you get some separation in thedirection you want.S2S1To do this list the components in increasing boiling point and determine keycomponents.

Replace the flash by a three plates column, with similar specs as those given by theflash outlet streams. It should not be a big problem to get it.5. Add the components that are missing. Do it slowly, increasing their concentrationuntil you reach the desired values.6. Keep tightening the specs and increasing the number of plates accordingly, so thatyou meet the separation you want.ChE 4253 - Design I

Distillation column is one of the important equipment in the biodiesel plant. For a small scale plant usually batch distillation or packed column is used. For this project I use batch distillation column. The designing of the distillation column is using AVEVA PDMS with 3D design. Many benefit of 3D design will revealed when using this software.
the distillation column. This chapter presents background information for both distillation columns and bond graphs. 1.1 The basics of a distillation column The distillation column is a widely used apparatus used to separate various chemicals, most commonly petroleum products. Historically, distillation has been around for millennia.
Types of Distillation Column Batch Distillation Column The column is charged with a 'batch' and then the distillation process is carried out. When the desired task is achieved, a next batch of feed is introduced. A condenser to turns the vapors back to a liquid so they can be easily collected. Batch distillation comprises of tall column that is
case of distillation: cryogenic distillation. Distillation is a very common method used to separate two (ore more) components in a trayed or packed distillation column. Cryogenic distillation columns are operated at extremely low temperatures (80-100oK) to separate the desired component and to "waste" useless component. For a
mixture: simple distillation, fractional distillation, vacuum distillation and steam distillation. The chosen distillation method and extent of purification will depend on the nature of the mixture, and specifically the difference of the boiling points of miscible liquids. In distillation, the mixture is heated, vaporizing a substance.

distillation column consists of group of minima points as illustrated in Fig. 2. These minima points represent the position of trays inside the distillation column which carry . (i.e. valves and bubble caps). All this reasons makes the pressure exerted by vapour is insufficient to hold liquid on a tray. Weeping is a distillation column .
