Re: Explosivity off-gas MP inerts washing tower
Dear Sara,
There are following manner to avoid explosive mixture
1. To remove Hydrogen in CO2 Compressor.
2. To add NG in MP condenser (in case of recovery of inerts gas as fuel.)
3. To add steam in MP vents d/s if inerts gas not recovered(vent to B/D)
Danger of Choking Burner in case of recovering inerts as a fuel,
The NG is having some amount of CO2 (2-5% depends upon source), so the Carbonate/Carbamate formation takes place and resulted choking of burner to avoid this phenomenon Some separate burner to be used for inerts fuel don’t mixed with NG.
If you remove Hydrogen in CO2 compressor then No question from recovering fuel because fuel(Hydrogen) already remove from Compressor.
How to reduce Ammonia in Inerts ?,
To increase the Cold Condensate(water) in inerts washing column(0.8-1.0 m3/hr)
And also read following useful links
