thermal oxidizer / fired heater
(OP)
Hi,
I have been given a design project where i have to design a thermal oxidizer to get rid of a stream of gas that consist of 86% nitrogen, 0.3% Methane and the rest CO2, H2 and H2O.
Should i use a thermal oxidizer or fired heater? which is easier? as im expected to do calculations on them etc.
Have not got a clue on where and how to start the task. Hope you could advice on this.
Thanks alot for your time.
Regards,
Julian.

The way I handle equipment that I am not familiar with is write up a performance specification and offer it for bid to some reputable companies. These companies can probably give you forms for the information they need.
Good luck,

If you have a fired heater doing something else (boiler, hot oil, process heater, etc) and the stream is small enouh, then putting a disposal burner in that is your absolute cheapest option. Otherwise these things are a matter of economics and there is no single answer.
What is the mass of the stream?

I am working on an thermal oxidizer and i am wondering if it can be assimilate to a fired heater ? I am asking that for knowing if API 560 will apply in my case.

You've got a lot of nitrogen which likely means an external fuel stream to support combustion (I doubt there's enough H2 to maintain combustion). If you have an existing fired heater you can dispose of waste gases in them but to dispose of this stream if an existing heater isn't available you really want an incinerator of some sort.
I suppose the methane prevents you from just venting it to the atmosphere?

For example, the EPA flags gases with less than 300 BTU/scf as being difficult to burn in a flare. 100% H2 is 325 BTU/scf but you would have no problem burning it in a flare
I'd talk to John Zink or another TO vendor, I'm not sure what the answer is.
