Hi Guys…
For Past so many days, missed my blogging instinct.
Now I’m back, with some spare time, lets start with Knowledge sharing!

Design of heat exchanger step :2 : which type?
The next step is to decide which type of exchanger to be used?
The industrial heat exchanger are varies depending upon
1. Transfer process.
2. Number of fluids
3. Compactness.
4. Constriction.
5. Flow arrangement.
6. Type of heat transfer.
See attached figure for more details.

Heat exchanger: step 1: application
<p>The first step dorm designing a heat exchanger is to understand where it will be used for.</p>
<p>Application is most important criteria and mostly its input from client.</p>
<p>Application demands understanding of functionaries expected, duty needed, properties of both side fluids, system information e.g presuredrop expected, cleaning method of the equipment, hazard category, local laws pertaining to pressure vessel and hazard handling.
Some time the application demand ‘soft’ heat transfer due to the media e.g yeast cooler due to delicate yeast cells are always co-current type which lead to higher surface area and are more costly than counter current heat exchangers; but due to application those are designed that way.
What is heatexchanger?
Yup, just a brief on this subject.
Heat exchangers are devices used to transfer heat energy from one fluid to another, gas to gas or gas to liquid.
Typical heat exchangers are seen around in most unexpected location. From household appliances as air conditioners, refrigerator etc. Boilers and condensers in thermal power plants are examples of large industrial heat exchangers. There are heat exchangers in our automobiles in the form of radiators and oil coolers. Heat exchangers are also abundant in chemical and process industries.
Heatexchanger sizes varies from couple of square mm (heat sink in computer cpu) to length exceeding hundreads of square meters!
From simple study flow to complex flows.
Heat exchanges as they say “comes in all sizes and nearly for all duties”
We will, in my next post discuss about fundamental of heat exchangers.
Heat exchanges… Google way.
If you Google the word you will get morecthan a billion results. That just shows how it closely associated to industry, to us.
But at the same time ut shows how wast the subject is.
The purpose of next few blows is to simplify your search by telling you what to ask and where to see.
Figures crossed 🙂

Thermosiphon Reboiler Design
After long days of calculation, rewriting calculations on pages! on excel! finally I come to some ‘lesson learn’ which I’ll be sharing now.
But before that, following are two good references to design a thermosiphone reboiler
1. Applied Process Design Volume-3 by Ludwig
2. Process Heat Transfer – D.Q. Kern
