This Topic I am writing in continuation of the topic which had been archived.
http://www.cheresour...iler-condenser/
The topic was ended there.
Going through the topic I found similar example which I would like to put it here so that some people can enlighten with knowledge on this thing.
The reboiler condenser vendor gives a recirculation ratio for a bath type reboiler condenser.
Which is provided to reduce the risk of hydrocarbon accumulation on condenser core.
The higher the recirculation ratio, it is better.
I have provided an example of such reboiler in attached excel sheet with all the data's that are available.
So on the safety point of view it is quite clear to me as much higher recirculation ratio would be there lesser would be the chance of hydrocarbon deposition.
So here in the example where the recirculation rate in the bath is 10 times the liquid actually evaporated.
The thing that still remains uncertain is how we arrive at this recirculation rate or recirculation ratio, like 10:1 in this case. In some cases I have seen this 20:1 or 6:1 in some instances.
This bath reboiling is occurring on the basis of natural convection for sure. So the density diffference is causing the recirculating flow. i.e. density difference is the driving force for the recirculating flow.
But still I am not able to understand/figure out the process in which the vendors are calculating/fixing the recirculation flow in these type of exchangers.
I would like to know if someone could enlighten us about the procedure of this design of these bath type exchangers w.r.t the recirculation ratio.
If any data's are required in this case please feel free toa sk I ll provide if I have the data.
Thanks and regards,
