In a sulfur recovery plant(CBA Process), currently incinerator temperature
is controlled at 600 deg.C. Is it wise to reduce upto 550 degC for
optimize fuel consumption. Other than ground level SO2 content , what is other effects.
I have seen in the literature that 1000 Deg F ( 538 degC)is sufficient for good
combustion of sulfur tail gas and a good dispersion of SO2 in ground level.
I would like to know what others are maintaing sulfur recovery plan incinerator temperature.

Regards.

If it is white smoke, H2S escape from the system .
If smoke is black, insufficient air is supplied. Which one
is your case?
For my concern is to reduce temperature without any effects of
other parameters.

Thanks for your time.

Hi Aanita,

I have seen SRU incinerators running at 550 deg cel and that will not be a problem at all.

Koli
can you give me some more details: is it a large SRU, what is the process( CBA or 3/4 stage Claus, stack details).

Thank you very much.

Thank you very much.

It's large SRU ( 675 TPD ) and CBA process.

Thankyou very much.
Is it's normal operating temperature (55o Deg C)or ocasionally
kept lower value. It looks same for my case:capacitywise and also it is CBA process.
For my case we operate 600 Deg C, however we are trying to maintain less than
current operating (600 Deg C)temperature. I am affraid, it will increase ground level SO2 concentration.

Regards.

Your SRU plant does not have steam drum for medium pressure (25 ksc) steam generation? I dont think you will be able to maintain this pressure with less temperatures.
