Thanks, Prabhu.

thanks for your reply latexman...Colud you be more explanatory on those pressure drop point...my interest of column to which i am going to design works under vacuum.

Hi all, Anybody has got a experience in designing of internal condenser to the column overhead. If so what is the primary criterion to opt for such type of condenser. Thanks in advance.... Prabhu.

Thanks joe for the valuable tips. do you have any idea on zone classification of PSV's ??? how do they do it ???? Is that LOPA is any way related with zone classification.

@ all thanks for your replies. @ Joe wong... joe is there any limits for Mach number in flare header...i have heard that there are some different mach number levels for main header,sub-header and psv tail pipe..... is it so ????? then how about noise levels ??? and vibration criteria ??? joe...

Guys, I just started to check the adequacy of the existing flare system which was built way back in 1950's. Initially i started doing the adequacy check for the existing PSV's so that i can make sure that i dont have any in adequate PSV's or inlet pressure drop offering valves. but my doubt...

Contatnt back pressure is northing but the pressure at the PSV tail pipe when it is in closed condition. Superimposed back pressure is northing but but the pressure at the PSV tail pipe when it is relieving.

Guys, In addition to that normal for fire sizing of LPG vessel better dont take any credit factors there by we can be even more safe.what u say ???correct me if wrong.

@ Homayun... yes i agree with you.....My system is not safe.

@ Lizking great reply..........Yeah i know i am screwed and if it is a liquid service we can apply square law.i escpaed by this on couple of devices. cheers...........

@ maddocks on 1st option - is it possible to fix a custom made orifice in a existing device(PSV)??? 2nd option - what do you mean by split load ???the problem i am facing here is the sizing flowrate is very less when compared to device rated flow.

@ insult to injury - no i face inlet pressure drop problem here..............

@ Lizking.Its a vapour service device...........

Say i have a PSV provided for a system in which the rated flowrate of the PSV is 10 times bigger than the required sizing flow rate.Ultimately my inlet and outlet pressure drop are not within the code limits.In this case is there any possible solution available other than going for a smaller...
