Gasification quench chamber and scrubber assembly

摘要

A gasification quench chamber is disclosed. The gasification quench chamber includes a reservoir that contains liquid coolant in its lower portion and an exit for the cooled syngas in its upper portion; a dip tube that is configured to introduce a syngas mixture to contact the liquid coolant which produces the cooled syngas; a cooling device configured to further cool the cooled syngas in its upper portion; and a stability device in the lower portion that is configured to mitigate coolant level fluctuation and sloshing. In an embodiment of the quench chamber, the cooling device includes a heat exchanger pipe. A quench chamber and scrubber assembly is also disclosed.

1. A gasification quench chamber comprising:
a reservoir having a liquid coolant disposed in a lower portion therein and an upper portion comprising an exit for exiting a cooled syngas therefrom; a dip tube configured to introduce a syngas mixture to contact the liquid coolant thereby producing the cooled syngas, wherein an outer surface of the dip tube and an outer periphery of the reservoir define an annular space for the cooled syngas to flow; a cooling device placed in the annular space in the upper portion of the reservoir and configured to both further cool the cooled syngas in the annular space and to increase an effective distance between the liquid coolant and the exit, wherein the cooling device comprises a heat exchanger pipe that is not contacting the dip tube; and a stability device in the lower portion, configured to mitigate coolant level fluctuation and sloshing.
