Abstract
A flameless thermal oxidizer apparatus for a gaseous stream containing hydrogen includes a vessel containing a ceramic matrix bed; and a dip tube extending into the ceramic matrix bed, the dip tube including a first flow path for a first stream having hydrogen therein, and a second flow path for a second stream having an oxidant therein to be mixed with the first stream for introduction into the ceramic matrix bed. A related method is also provided.
Claims9
A flameless thermal oxidizer (FTO) apparatus for a gaseous stream containing hydrogen, comprising:
- a vessel containing a ceramic matrix bed;
- and
- a dip tube extending into the ceramic matrix bed, the dip tube including a first flow path for a first gaseous stream having hydrogen therein, and a second flow path for a second stream having an oxidant therein to be mixed with the first stream for introduction into the ceramic matrix bed, wherein the dip tube comprises:
- (a) a first pipe having a first sidewall containing the first flow path and including at least one hole disposed through the first sidewall for releasing the first stream from the first flow path;
- and
- (b) a second pipe containing the second flow path, the second pipe sized and shaped to receive a portion of the first pipe in the second flow path such that fluid communication is provided to the second stream through the at least one hole,
- wherein the second pipe has an outlet end that is positioned to deliver the mixed first and second streams into the ceramic matrix bed of the vessel.
