What is the use of kettle reboiler?

What is the use of kettle reboiler?

A kettle reboiler is designed to allow a heating fluid to pass through tubes that are covered in the liquid you want to be distilled. As the liquid heats up and boils, it is sent to the distillation column and condensed by cooling liquid.

Why kettle reboiler can be used as a gas cooler?

Kettle reboilers are reliable in that they can handle high vaporization of up to 80 percent and are easy to maintain. The liquid from the bottom of the tower flows through the tube bundle and exits as condensate. A restraining device (baffle) controls the liquid level over the bundle.

Where the reboiler is mostly used?

industrial distillation columns
Reboilers are heat exchangers typically used to provide heat to the bottom of industrial distillation columns. They boil the liquid from the bottom of a distillation column to generate vapors which are returned to the column to drive the distillation separation.

What is the difference between kettle type and thermosyphon reboiler?

The vertical thermosyphon reboiler is less susceptible to fouling problems and in general has higher heat transfer coefficients than does the kettle reboiler. However, additional height is required in order to mount the reboiler.

Is a kettle a heat exchanger?

A kettle is a shell and tube exchanger.

What is thermosyphon principle?

The principle of the thermosyphon system is that cold water has a higher specific gravity (density) than warm water, and so being heavier will sink down. Therefore, the collector is always mounted below the water storage tank, so that cold water from the tank reaches the collector via a descending water pipe.

Is a vaporiser a heat exchanger?

Water bath vaporizers are a special type of coil-wound heat exchanger. They are used in petrochemical and cryogenic plants to vaporize liquefied gases such as oxygen, nitrogen, argon, ethylene, propylene, and natural gas.

What is reboiler duty?

The energy consumption is commonly referred to as reboiler heat duty because the total energy for solvent regeneration is provided by hot steam passing through a reboiler at the bottom of a regeneration column.
