Hi, I have a question about flare tips

I know that if you burn gas you can use a pipe flare tip and if you burn liquid you will use a liquid burner one, my question is how about burning a mix of both gas and condensate, you can assume I will burn 100 MMscfd of Gas and 6500 BBL of condensate so What kind of flare tip should I choose for this case? 



Any suggestion please 


Thank you

For burning a gas and liquid mixture you need a burn pit and a ground flare design. You cannot use an elevated flare for gas-liquid mixture since any incomplete combustion or partial burning at an elevated flare due to any pilot failure can lead to burning rain and crate a serious hazard to personnel and environment. That is the primary reason that you have a Flare Knockout drum upstream of an elevated flare to ensure all liquid is knocked out in the knockout drum and only gas is burnt at the elevated flare.


Most vendors such as John Zink, Callidus and Zeeco can provide a "Totally Enclosed Ground Flare" which can handle a gas-liquid mixture. You are advised to contact these reputed vendors to get an idea of the design and cost of such ground flares.

Thank you for your response ankur2061

In fact I have already designed the burn pit and I am using an horizontal flare stack, but I am not sure about the tip type, because I wonder what will happen for example If I burn gas in a liquid burner tip or liquid in a pipe tip,


In othe words  what is the difference in structure for these kind of tips that make them work with a gas or a liquid. 


Sorry I forgot to mention that I am using a simulator and I know that I can buy a tip for this mixture, I am just not sure about the tip type I should select for the run since I dont get too much options on there.

All ground flares shall be smokeless design. John Zink has a product (flare tip) "Kaldair Condair" which seems capable of handling liquids also.

kimchiliciosa; I think the question is about what is the matematical basis of the selection of TIP in FLARESIM, if it is PIPE or welltest. What happens if i use welltest and i there will be only Gas. 


best regards
