Pressure relief to protect system from overpressure and emergency depressuring to evacuate system inventory to safe location are common plant safety system. Fluid is discharge in the proper designed collection system will then be send to flare for proper combustion. Different fluid characteristics, pressure available in the collection header, carbon-hydrogen ratio, concentration of toxic component, local requirement, etc will require different type of flare tip for proper flaring.
There are several typical flare type :
A simple flare selection chart has been provided to ease process engineer in flare tip type selection.

There are several typical flare type :
- Pipe flare (subsonic)
- Sonic flare (single tip & multiple tips)
- Coanda tip (single & multiple)
- Steam assisted flare tip
- Air assisted flare tip
- Enclosed flare
- Endothermic flare
- Liquid burner
- Other proprietary tip

Hi friends,
I m praveen kumar as a Piping Er in India.
I want need Flare Piping Routing once line has be
downward position then upward is accepted or not.
just clarify.
mail me
praveenkumar.sek@gmail.com
Praveen,
Flare header is commonly slope to Flare KOD drum, which used to collect liquid and recover back to process system (or evacuate to liquid burner). Flare piping slope downward and upward again may results all problems i.e. liquid accumulation, corrosion, slugging, vibration, etc. It is always NOT recommended.
Praveen,
Recommend you to read this post.

Dear all,
I'm looking find Sonic Vent Tip, please advice supplier.
Kindly inform to email "alpha.pei.group@gmail.com"
Thanks.
Aplha Pei,
Most flare tip vendors supply Sonic flare tip. There are
John Zink
EET
GBA
Flare Industries
Callidus
However, i have not heard of sonic vent tip.
what is the pressure drop for coanda sonic flare tip self ignited for 10 mmscfd capacity?
Typically pressure drop can be few bar (3-7 bar) for sonic tip. Please confirm with John Zink.
