How a Tubular Heat Exchanger Works

A tubular exchanger is a type of heat exchanger with tubes encompassed in a shell. It is a very common device in industries where the focus is recovering heat from gas or liquids.

The principle of the shell and tube heat exchanger is based on a bundle of tubes that is arranged vertically or horizontally inside a so-called shell.

It works by exchanging heat between two fluids. One is the "heating" and the other is the "heated" fluid.

The fluids can be of various natures and the tubular exchanger can be used for the exchange of gas/gas, liquid/liquid, liquid/gas, etc.

There are different categories of shell and tube heat exchangers on the market, each one designed for a specific application:

Condenser: In this configuration, the purpose of the exchanger is to allow the transformation of a gas into a liquid. The role of the exchanger, as its name indicates, is to condense steam on a cold surface. The condenser is therefore a refrigeration system that allows a heat exchange between a refrigerant and an external medium, ensuring the change of state of the fluid at constant pressure and then its desuperheating as well as its sub-cooling. This way, the fluid leaves the condenser in a liquid state and no longer as a gas.

Cooler: This time, the role of the exchanger is to cool a liquid.

Boiler: The main purpose of this process is to partially vaporize the bottoms of the distillation columns. A mixture of liquids or a mixture of liquids and solids is vaporized. This process is also used for heating.

Heater: Capable of operating in extreme conditions, the purpose of the heater in industries is to heat a volume of liquid or gases.

Evaporator: Its purpose is to concentrate a solution thanks to a contribution of energy to carry out a change of state from the liquid phase to the gaseous phase.

Crystallizer: In this last configuration, the exchanger will allow to isolate a product to retrieve it from a solution in a solid form.
