Heat Exchanger

Heat exchanger is equipment widely used both upstream and downstream facilities, built for efficient heat transfer from one medium to another. Heat exchangers are classified by flow arrangement, parallel flow and counterflow. Parallel flow (cocurrent) is flow when two fluids enter the exchanger at the same end and travel parallel to one another to the other side. Counterflow (countercurrent) is when two fluids enter the exchanger from opposite ends.

Coolers:

• Air-cooled

• Cooling towers

Commonly used types:

• Shell and tube

• Plate

• Plate fin

• Air cooled

In oil and gas facilities, following types are commonly used:

Commonly used:

• Bath heaters

• Indirect

Fluid-fluid:

• Shell and tube

• Double pipe

• Plate and frame

Uses of heat exchangers may vary depending on the process requirements, such as heat and cool fluids, heat recovery, separation, reboiling, condensing.

Shell And Tube Heat Exchanger

Shell and tube heat exchanger consist of a bundle of tubes and shell. Heat transfer occurs when one fluid that needs to be heated or cooled flows through the tubes and the second fluids runs over the tubes that provides the heat or absorbs the heat required.

Configuration

Configuration depends on each process requirements. Main consideration for the design should be fluid involved, corrosion potential, problems of cleaning, pressure drop, heat transfer efficiency, tubes usually 20 ft. and 20ft.

Performance advantages

1.Stable and reliable structure: The shell and tube heat exchanger adopts a structure composed of tubes and a shell. Heat exchange occurs between the fluid inside the tubes and the fluid outside the shell. The structure is stable and reliable, capable of withstanding high pressure and temperature.

2.Strong adaptability: The shell and tube heat exchanger can adapt to different process requirements and operating conditions. It can handle different types of fluids, including liquids, gases, and steam.

3.High efficiency: The shell and tube heat exchanger has high heat transfer efficiency, enabling efficient heat transfer, improving energy utilization, and reducing energy consumption.

4.Convenient maintenance: The structure of the shell and tube heat exchanger is relatively simple, making it easy to clean and maintain. This helps reduce downtime and maintenance costs.

5.Strong corrosion resistance: Since corrosive media often need to be handled in industrial applications, the shell and tube heat exchanger is usually made of corrosion-resistant materials. It can effectively resist corrosion and prolong service life.

The advantages of our shell and tube heat exchanger are as follows: compact and reasonable structure, high heat exchange efficiency, high temperature and high pressure resistance, long service life;smooth inner wall and poor adhesion which is not easy to scale.
