Classification of heat exchangers according to construction
What is a heat exchanger? A device to exchange the thermal energy between two or more fluids at different temperatures. In simple terms; if you want to use a hot fluid to heat up a colder one you can use a heat exchanger to do the job. Heat exchangers are […]
What is Shell and Tube Heat Exchanger
Shell and Tube heat exchanger uses Shell and Tube Heat Exchangers are the most commonly used in the chemical processing industries today. It possesses large surface areas for heat transfer and is capable of operating at high temperatures and pressures. Shell and tube heat exchangers are frequently selected for applications […]
What is a Plate heat exchanger
What is a Plate Heat Exchanger? Plate heat exchangers are essentially a number of pressed metal plates, aligned on a frame clamped together with gaskets between the plates. Each pressed plate is corrugated, having a number of alternating ridges and grooves. The pattern and geometry of the corrugations are a […]
What is a Double pipe heat exchanger
Quick description What is a double pipe heat exchanger? Double pipe heat exchanger is perhaps the simplest of all heat exchanger types. Double pipe heat exchangers are also known as hairpin, jacketed pipe, jacketed U-tube and concentric pipe. These styles of double pipe may have a bundle of inner tubes rather […]
Recommended Shell and Tube side velocities
Recommended shell and tube side velocities values are listed below, the values can be used for preliminary design purpose when designing shell and tube heat exchangers, these are guidelines that are in place as lower velocities can cause fouling issues and very high velocities can cause erosion issues. If there […]
How to use shell and tube heat exchanger software effectively
How to use shell and tube heat exchanger software effectively? This short article aims to give some recommendations and guidelines on how to effectively use shell and tube heat exchanger software (S&THex) effectively to design a heat exchanger, the article may also answer questions such as how do I know […]
How to adjust pressure drop in heat exchangers
How to adjust pressure drop in heat exchangers This is a quick guide on how to adjust the pressure drops in shell and tube heat exchangers. This short article assumes that you are in a simulation stage and have already calculated both shell side pressure drop and tube side pressure […]
Compressors a general guideline
Compressors a general guideline This short article discusses some general guidelines for industrial compressors. The purpose of this article is to provide a quick summary of findings for general understanding. It is assumed that you have a general understanding of industrial compressors.
How to calculate the heat duty for heat exchangers
How to calculate the heat duty for heat exchangers? Lets first define the term “Heat duty” to understand what understand what exactly we are calculating. The Heat duty can be defined as the amount of heat needed to transfer from a hot side to the cold side over a unit […]
