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… Continue reading
Shell and tube heat exchangers comparison
The table below compares different type of shell and tube heat exchangers based on different design characteristics:
+ Fixed tube sheet + U Tube + Packed Floating Head + Internal Floating Head + Outside… Continue reading
Difference between Shell passes and Tube passes
In shell and tube heat exchangers the number of shell passes or the number of tube passes will always come across. The number of passes in general affects your pressure drops in shell and tube heat exchangers. This short article will show the difference between them for quick reference.
Tube Passes
The tubes are arranged within the shell and tube heat exchangers in passes. The passes can be One, Two, Four, Six or Eight.
This arrangement can be illustrated in the figure below:
Two tube passes
Shell and Tube Condenser Design with Condenser Design (CnD) software

CnD is a software that is made to demonstrate thermal analysis and design calculations required for designing shell and tube condensers. This software can design, horizontal shell side condensers, horizontal tube side condensers, vertical shell side condensers, vertical tube side condensers and reflux condensers. This software application is intended for use by professional and academics in the engineering industry. Some basic understanding in thermodynamics, fluid flow and shell & tube heat exchangers is required before attempting to use this tool.Below is a list of main features: Continue reading

Shell and tube heat exchangrs can be divided into three major parts, these parts are the front head, shell section, and rear head. Each of these components is available in a number of standard designs. This article only discuss the designations provided in TEMA standards. Continue reading
Heat exchangers comparison
The tabel below compares different heat exchangers mainly common types Continue reading
Stream allocation is an important decision in heat exchanger design. This decision can impact the heat exchanger life, can also make the difference between higher and lower maintenance costs. Can also have a high impact on the thermal performance the heat exchanger. This short article aims to discuss the process of determining the fluid allocations in shell and tube heat exchangers. The decision is made based on the criteria below: Continue reading
