Can I maintain slope of 1:100 in horizontal flare kod having one inlet and two outlet nozzle .

Dear Alok,

Your query is not clear. Would you please elaborate.
I assume that you are trying to maintain slope in flare KOD inlet header and flare KOD outlet header. Yes, slope is required to be maintained in KOD inlet and outlet headers towards KOD irrespective of the type of Flare KOD.

Yes slope of 1:100 is the min value that can be used for KOD.
What do you mean by two outlet nozzles ?

I mentioned slope in KOD not in inlet and outlet headers... and KOD is going to operate with one feed nozzle and two gas outlet nozzle.

Dear alok..
Why do you need a slop in KOD..Though there is nothing wrong to give a slop to KOD as per process part is concerned but may have installation/fabrication complexcities. I wonder wt benifits you are goin to get by tilting the KOD? If you have any specific process requirement please elaborate.

Dear Friend,

I know all that you mention and because of that I designed normal KOD without any slope but my client has special problem in draining out in their existing KOD thats why they insists for slope. I just little more cautious while offering them my design.

you should not post same question to two different forums ,this is the answer to question as replied by me in Refining forum.

"Dear Sir
Can you specifically mark your concerns here may be what i can understand is that you are worried about vapor space reduction because of slope .If this is the case you have to re think that slope 1:100 is so low that there's practically constant vapor space in the KOD,only thing slope helps is towards free draining of KOD. "

Additionally yes i do specify 1:100 slope for flare KODs as a general design practice.

Dear Himanshu ,

thanks for reply .

As you mentioned that as a general practice you specify 1 : 100 slope for flare KODs but I want to suggest you that please go through API 521 and shell DEP.

You may have specified slop for underground vessel.
