what is distillation, types of distillation, internal of distillation column, Do you know DCS/PLC

Question

Accepted Answer

Distillation is a separation process used in chemical engineering to separate components of a liquid mixture based on their boiling points.

Distillation is a separation technique used to purify liquids or separate liquid mixtures.
It relies on the differences in boiling points of the components in the mixture.
The process involves heating the mixture to vaporize the more volatile component and then condensing it back into a liquid.
The condensed liquid is collected as the distillate, while the less volatile components remain in the original mixture.
Types of distillation include simple distillation, fractional distillation, and vacuum distillation.
In a distillation column, the mixture is introduced at the bottom, and as it rises through the column, it undergoes repeated vaporization and condensation stages.
The column is equipped with trays or packing material to enhance the separation efficiency.
DCS (Distributed Control System) and PLC (Programmable Logic Controller) are automation systems commonly used in industrial processes like distillation.
DCS and PLC help monitor and control various parameters such as temperature, pressure, and flow rates in a distillation process.

Distillation is the one type of separation process it is based upon the relative voltality and boiling point

Normal distillation, vacuum distillation, adiabatic distillation etc.

Dcs full form Distributed control system

Plc full form programmable logic control.
