Moisture removal for gasification quench chamber assembly

Abstract

A gasification assembly that includes a quench chamber and downstream transfer piping is disclosed. The gasification assembly includes the quench chamber and a liquid coolant disposed therein, and a dip tube that is configured to couple a combustion chamber to the quench chamber and also configured to direct syngas from the combustion chamber to the liquid coolant and produce a cooled syngas. The assembly further includes a transfer pipe that is in fluid communication with the cooled syngas and configured to transfer the cooled syngas to a downstream scrubber component. The transfer pipe further includes an excess moisture removal device, which is configured to remove moisture from the cooled syngas.

1 . A gasification assembly comprising:
 a quench chamber having a liquid coolant disposed therein;   a dip tube configured to couple a combustion chamber to the quench chamber and configured to direct syngas from the combustion chamber to the liquid coolant and produce a cooled syngas; and   a transfer pipe in fluid communication with the cooled syngas, configured to transfer the cooled syngas to a downstream scrubber component, wherein the transfer pipe further comprises an excess moisture removal device, configured to remove moisture from the cooled syngas.   
     
     
         2 . The gasification assembly of  claim 1 , wherein the excess moisture removal device is configured to employ centrifugal action to remove moisture from the cooled syngas. 
     
     
         3 . The gasification assembly of  claim 2 , wherein the excess moisture removal device comprises a baffle. 
     
     
         4 . The gasification assembly of  claim 1 , further comprising a return line in fluid communication between the moisture removal device and the quench chamber configured to return a portion of the removed moisture to the liquid coolant. 
     
     
         5 . The gasification assembly of  claim 1 , wherein the excess moisture removal device injects a fluid at the exiting syngas, wherein the fluid has a higher temperature than the exiting syngas, thereby evaporating a portion of the moisture. 
     
     
         6 . The gasification assembly of  claim 5 , wherein the fluid is a hot syngas. 
     
     
         7 . The gasification assembly of  claim 6 , wherein the fluid is provided from a gas turbine. 
     
     
         8 . The gasification assembly of  claim 1 , wherein the excess moisture removal device comprises a plurality of perforations configured to allow egress of the removed moisture from the transfer pipe. 
     
     
         9 . The gasification assembly of  claim 8 , further comprising a return line in fluid communication between the plurality of perforations and the quench chamber configured to return a portion of the removed moisture to the liquid coolant. 
     
     
         10 . The gasification assembly of  claim 8 , wherein the plurality of perforations are in fluid communication with a reservoir. 
     
     
         11 . The gasification assembly of  claim 8 , further comprising a cooling device in fluid communication with one of the transfer pipe and the excess moisture removal device, configured to condense moisture from the cooled syngas. 
     
     
         12 . The gasification assembly of  claim 11 , wherein the cooling device comprises a sleeve partially surrounding a portion of the transfer pipe, further wherein the sleeve has a fluid therein having a temperature less than a temperature of the cooled syngas in the transfer pipe.
