Hello,

I have been currently tasked with designing a total overhead condenser for a methanol distillation column. In the condenser, for simplicity reason, have I said that a pure vapour methanol product enters the condenser. From the sources, I have concluded that the best action would be a shell and tube, which is horizontal, and the condensation takes place on the shell side. From this, I will also have cooling water running through the tube side. From the literature studied, I cannot find an equipment sizing procedure to work out the overall heat coefficient, which is then used to work out the transfer heat area for the heat exchanger stated, so I wondered if anyone has any guidance or references that can help me through it. I have access to simulation on ChemCAD in where I can obtain any physical properties.

 

I would use `Engineering Sciences Data Unit Design Guide, ESDU 84023`, but I don't have access to it, neither does my university, which is proposed in Coulson and Richardson.

 

Heat Exchanger Type: Shell and Tube

Orientation: Horizontal    

Condensation occurs in the Shell Side

Totally condensed

Hot stream: Pure Methanol

Cold Stream Cooling Water

Thanks

Hi,

Give a try !

hello

 

Hereafter you will find the link to download the Book Process Heat Transfer from Donald Kern.. This book was the one in the 80 years, when simulators were a dream, we use to design HE.. You will find all than you need do your assignment.  Check you will calculate a condenser; it has a chapter for it.

Hi,

Definitely the reference "process heat transfer " by D.Kern is a very good choice to learn about the principles and the details of mechanisms.

To me there is another good book with examples and excel sheets Engineers should consider :

Heat transfer in process engineering by Eduardo Cao 

 

Good luck

1) Process Heat Transfer: DQ Kern

2) Ludwig's Applied Process Design for Chemical and Petrochemical Plants

 

These are the two books I would recommend

Hi,

Consider to read the doc attached  related to vacuum condenser .

Good luck
