Dear all

I need to burn a flow gas of 100-1000 kg/h of 1,3 Butadiene. The upstream pressure of Vent pipe is 1-2 barg. I don’t know if I have to design an Incinerator , or a Flare! Any assistance? Do you guys have any documents?

Regards

Hi,

 

Why would you want to burn such component?!

[process-man]

Hi Naser,

In my plant , there are several Horizontal Storage Tanks of 1,3 Butadiene from which the Feed of Process is to be supplied. But during loading and unloading of these tanks , and even during popping up the tanks PSV’s , I have to burn the gas stream of this component.

What shall I do , If I don’t want to burn that?

 

Any recommendation?

You should add a condenser for routine operation. Sounds like this has been operating for some time. Don't ever burn anything if there is an alternative.

Hi process-man,

 

I think 100-1000 kg/hr flow of 1,3 Butadiene is so high for which considering a VRU (vapor recovery unit) instead burning to be reasonable in economical and emission reduction standpoints...

Normally Butadiene 1-3 should be stored under low temperature ( below 10C) to prevent pressure built up and release .

 

Check the data attached .

 

hope this helps.

To Fallah's point, assuming a 99% destruction efficiency in a flare, at the high end of your flow rate estimation, you would be emitting 22 lbs/hr of butadiene into the atmosphere. In the United States, a release of 100 lbs over a 24-hour period qualifies as a "reportable quantity," a significant release.

To Fallah's point, assuming a 99% destruction efficiency in a flare, at the high end of your flow rate estimation, you would be emitting 22 lbs/hr of butadiene into the atmosphere. In the United States, a release of 10 lbs over a 24-hour period qualifies as a "reportable quantity," a significant release.

 

Can you please share a source or links?

[Dan Putt]

Sure, Shvet. First off, my apologies. The RQ is actually 100 lbs. I edited the above comment to reflect that. in the high flow case, the limit would still be exceeded.
