Which side of a shell and tube exchanger we should pump the high viscous fluid and what is the reason behind it?

Making Your Selection

Heat exchanger	Average gap (mm)	Fiber length (mm)
Typical industrial plate	2.4-3.95	1
Typical sanitary plate	3.95	1
Low contact point plate	3.95	5
Shell-and-Tube

Which fluid should be allocated to tube side in shell and tube exchanger?

A viscous fluid on the tube side tends to have high pressure drop and low heat transfer. That favors shell-side allocation. However, high pressure drop on the shell side can prompt significant flow bypassing around baffles, reducing heat transfer.

Should hot fluid be in the shell or tube?

If the heat exchanger is heating/ cooling the process fluid: If the HX is heating the process fluid, the process fluid should be on the shell side and the heating fluid on the tube side. Since the only way to lose heat for the heating fluid is through the tube.

Which heat exchanger is used for viscous liquid?

Suited for applications where the fluids have relatively low viscosity with no particles, the plate heat exchangers also can be used where the product outlet temperature is close to the service inlet temperature. They consist of thin, corrugated plates packed inside a frame.

Which fluid should be in shell side and tube side?

Fluid with higher flow rate is generally preferred to be kept on the shell side. Service where a large temperature change is desired is also kept on the shell side, where temperature change can be achiever by increasing the length of the exchanger.

How do you choose tube side and shell side fluid?

The more corrosive fluid should be on the tube side since it will only corrode the inner side of the tube. If it allowed on the shell side then the fluid will corrode the outer wall of the tube as well as the inner wall of the shell.

Why is viscous fluid on the shell side?

Generally speaking, more viscous fluids should go on the shellside because these fluids typically have a low heat-transfer coefficient. Putting them on the shellside can maximize heat exchange efficiency. Viscous fluids also tend to have a higher pressure drop.

How is the heat transfer in conduction?

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster. As these molecules collide, thermal energy is transferred via conduction to the rest of the pan.

Which one of the following fluid Cannot be placed in the shell side?

Which one of the following fluid cannot be placed in the tube side? v. High pressure stream.

Which of the fluid Cannot be placed on tube side?

How do you select tube side and shell side fluid?

What is the direction of heat transfer through solid materials?

In solids, heat passes from one point to another through conduction. In Liquids and gases, heat transfer takes place by convection. Heat transfer takes place by the process of radiation when there are no particles of any kind which can move and transfer heat.

Should more viscous fluids be placed on the shellside or sideside?

Generally speaking, more viscous fluids should go on the shellside because these fluids typically have a low heat-transfer coefficient. Putting them on the shellside can maximize heat exchange efficiency. When using this strategy a staggered tube configuration can further improve heat transfer capabilities, as this will promote greater turbulence.

What is the difference between shell side and tube side fluid?

A viscous fluid on the tube side tends to have high pressure drop and low heat transfer. That favors shell-side allocation. However, high pressure drop on the shell side can prompt significant flow bypassing around baffles, reducing heat transfer.

Which side of the fluid service is better to be kept?

With these factors in mind, following fluid services are better kept on the shell side. When more viscous fluid is kept on the shell side, the increased turbulence will result in increased heat transfer coefficient and improved overall heat transfer. Fluid with higher flow rate is generally preferred to be kept on the shell side.

Which fluid should go on the shell side of a exchanger?

When designing a shell-and-tube exchanger, one of the first issues is deciding which fluid should go on the shell side and which on the tube side. So, let’s look at some rules-of-thumb for several key factors, realizing such rough guidelines won’t cover all cases. High pressure. Put a high-pressure fluid on the tube side.
