Abstract

The present application provides a gasifier for creating a flow of a syngas. The gasifier may include a reaction chamber and a quench chamber. The quench chamber may include a number of integrated scrubber trays therein such that the syngas first enters a quench pool via a dip tube and then passes through the scrubber trays before leaving the quench chamber.

First claim

We claim:

1. A gasifier for creating a flow of a syngas, comprising:
a reaction chamber; and
a quench chamber;
the quench chamber comprising a plurality of integrated scrubber trays therein,
wherein the plurality of scrubber trays comprises a plurality of perforations therein,
wherein the plurality of scrubber trays comprises a plurality of protrusions extending downward from a bottom of the plurality of scrubber trays and positioned about the plurality of perforations.

2. The gasifier of claim 1 , wherein the quench chamber comprises a quench ring therein.

3. The gasifier of claim 2 , wherein the quench chamber comprises a dip tube extending from the quench ring.

4. The gasifier of claim 3 , wherein the quench chamber comprises a flow of water extending from the quench ring and down the dip tube.

5. The gasifier of claim 4 , wherein the flow of water comprises an outer film and an inner film along the dip tube.

6. The gasifier of claim 4 , wherein the flow of water is in a counter flow arrangement with a flow of cooled syngas.

7. The gasifier of claim 3 , wherein the quench chamber comprises a quench pool downstream of the dip tube.

8. The gasifier of claim 3 , wherein the plurality of scrubber trays are positioned about the dip tube.

9. The gasifier of claim 3 , wherein the dip tube comprises a downward path for a flow of hot syngas.

10. The gasifier of claim 1 , wherein the quench chamber comprises a syngas outlet.

11. The gasifier of claim 1 , wherein the plurality of protrusions comprises a sharp, pin-like shape.

12. The gasifier of claim 1 , wherein the plurality of scrubber trays comprises an upward path for a flow of cooled syngas.

13. A method of cooling and scrubbing a flow of syngas in a quench chamber, comprising:
flowing hot syngas down a dip tube;
cooling the hot syngas in a quench pool;
flowing the cooled syngas through a plurality of scrubber trays; and
counter-flowing water along the plurality of scrubber trays to scrub the cooled syngas,
wherein the plurality of scrubber trays comprises a plurality of perforations therein,
wherein the plurality of scrubber trays comprises a plurality of protrusions extending downward from a bottom of the plurality of scrubber trays and positioned about the plurality of perforations.

14. A quench chamber for cooling and scrubbing a flow of a syngas, comprising:
a quench ring;
a dip tube extending from the quench ring;
a quench pool; and
a plurality of scrubber trays positioned about the dip tube,
wherein the plurality of scrubber trays comprises a plurality of perforations therein,
wherein the plurality of scrubber trays comprises a plurality of protrusions extending downward from a bottom of the plurality of scrubber trays and positioned about the plurality of perforations.

15. The quench chamber of claim 14 , further comprising a flow of water extending from the quench ring and down the dip tube and the plurality of scrubber trays.

16. The quench chamber of claim 15 , wherein the flow of water comprises an outer film and an inner film along the dip tube.
