What happens in stripping section of a distillation column?

What happens in stripping section of a distillation column?

At the stripping section, the down-flowing liquid is stripped of the more volatile component by the rising vapour. The distillation can be equipped with trays or packings or both. This is a heat exchange equipment for condensing the hot vapour leaving the top of the distillation column.

What is the function of stripper column?

Stripping columns are used to remove volatiles from water such as volatile hydrocarbons (e.g., benzene, toluene and xylene), volatile chlorinated hydrocarbons (e.g., per and tri) from water. The Logisticon stripping columns are made of the so-called countercurrent principle.

What is striping section?

The section in a distillation column located below the feed point, in which the less volatile component or components in the mixture undergoing separation increase in concentration towards the bottom of the column as the more volatile component or components are stripped out.

What does stripping column mean?

A Stripping Column is a chemical equipment used for physical separation, where one or more components are removed from a liquid stream by a vapor stream. In industrial applications, the liquid and vapor streams can have co-current or countercurrent flows. Stripping works on the basis of mass transfer.

What is the difference between distillation and stripping?

What is the difference between stripping and distillation? The primary difference is in the method used to separate the feed’s constituents. While distillation uses heat to boil the volatiles into vapor and then condense and remove them, stripping uses the principles of absorption.

What is bottom of distillation column?

The vapour raised in the reboiler is re-introduced into the unit at the bottom of the column. The liquid removed from the reboiler is known as the bottoms product or simply, bottoms. The vapour moves up the column, and as it exits the top of the unit, it is cooled by a condenser.

Why stripping is done?

Ligation and stripping is also done when pooling of blood occurs secondary to venous incompetence, and patients suffer from symptoms of venous insufficiency. These symptoms include leg swelling, skin changes, pain and, in severe cases, ulceration.

What is the difference between scrubbing and stripping Where would stripping be used?

Put simply, scrubbing is the process of taking any damaged layers of finish off of your floor and then refinishing it as appropriate. Stripping, on the other hand, is the process of removing all finish that may be on the floor and refinishing it as through it were a new floor.

What are the types of distillation column?

There are two main categories of distillation columns, batch and continuous.

What is a rectifying column?

[′rek·tə‚fī·iŋ ‚käl·əm] (chemical engineering) Portion of a distillation column above the feed tray in which rising vapor is enriched by interaction with a countercurrent falling stream of condensed vapor; contrasted to the stripping column section below the column feed tray.

What is the difference between top scrubbing and stripping and refinishing?

What is the difference between scrubbing and stripping?

Stripping is the complete removal of any finish on the floor by means of a harsh stripping solution and aggressive stripping pad. Scrubbing is the removal of one coat of dirty/damaged finish and application of one or two coats of finish to rebuild rather than fully replace.

Where does the feed go in a distillation column?

A conventional distillation column has the feed going in somewhere near the middle of the tower. The section below the feed is the stripping section, and above the feed is the rectifying section. In a stripper, the feed goes in at the top of the tower and a gas (steam, hot air, fuel gas) is fed into the bottom.

How is separation achieved in a distillation system?

Separation is achieved by controlling the column temperature and pressure profiles to take advantage of differences in the relative volatility of the mixture components and therefore tendency to change phase.

What are the basic principles of a distillation column?

This article describes the basic principles and operation of a distillation column and the equipment and terminology used when discussing distillation. The basic objective of distillation is to take a liquid mixture and separate it into two or more streams which have compositions different to the feed stream.

What happens at the bottom of a distillation tower?

Steam or hot air is introduced at the bottom and it makes contact with liquid in counter current fashion either in a packed or tray tower. As the liquid proceeds down the tower it becomes leaner in organic material and vapor which rises up becomes richer in organic material. In this way clean water is collected at the bottom of the tower.
