Low pressure emergency flares
Low pressure emergency flares
(OP)
Dear all,
I am working on a project of biogas plant. In normal situation, the biogas (compressed to 150 mm water gauge) will be used in boilers or flared. In case of failure of the gas compression unit, the biogas pressure will increase in the reactor, and when it exceeds 4 mm H2O, valves will open to allow gas release in emergency stacks. Due to high H2S content of the biogas and high risk of intoxication, I am not satisfied by this option and would like to know whether there are emergency flares working with gas pressure as low as 4 mm H2O?
For your information, the biogas production is about 6,000 Nm3/h, with 55% CH4, 38% CHO2, 3% H2S.
Thank you in advance for your help.

RE: Low pressure emergency flares
My best advice is that you contact the John Zink Company at www.johnzink.com
Meanwhile, what is CHO2? Is that not a radical rather than a compound?

CHO2 was a typing mistake, it should be CO2.

It says that normal pressure is 150 mm H2O, but that the PSV opens at 4 mm?

I would concentrate to stop the reaction in the ractor automatically when the compressor fails rather than installing a low pressure flare!
Or consider installing a second compressor..

What is the other 4% volume made up of ?
