Method and system for improved reactant mixing and distribution

Abstract

One aspect of the present invention relates to a mixing system for use in a chemical-process column. The mixing system includes a heavy-reactant mixing surface arranged perpendicular to a flow of reactant through the chemical-process column. The mixing system also includes an aperture formed in the heavy-reactant mixing surface. A pre-distributor is coupled to an underside of the mixing system and fluidly coupled to the aperture.

What is claimed is: 
     
         1 . A method of mixing reactants in a chemical-process column, the method comprising:
 introducing a heavy reactant to a mixing region of the chemical process column;   contacting the heavy reactant with a heavy-reactant mixing surface;   homogenizing the heavy reactant within a mixing pot; and   distributing the heavy reactant via a pre-distributor.   
     
     
         2 . The method of  claim 1 , comprising directing the heavy reactant toward the mixing pot via a baffle. 
     
     
         3 . The method of  claim 1 , comprising mixing the heavy reactant with a vane disposed at an entrance to the mixing pot. 
     
     
         4 . The method of  claim 1 , comprising mixing the heavy reactant via at least one of a vane, a deflector, a baffle, or a static mixer disposed within the mixing pot. 
     
     
         5 . The method of  claim 1 , comprising:
 introducing a light reactant to the mixing region of the chemical process column;   directing the light reactant through the heavy-reactant mixing surface via a light-reactant duct; and   mixing the light reactant via a vectoring member fluidly coupled to the light-reactant duct.   
     
     
         6 . The method of  claim 5 , wherein the vectoring member is arranged proximate to the pre-distributor. 
     
     
         7 . The method of  claim 1 , wherein the distributing comprises directing the heavy reactant through a plurality of channels fluidly coupled to the mixing pot, the plurality of channels having a plurality of perforations formed therein. 
     
     
         8 . The method of  claim 1 , wherein the homogenizing comprises inducing turbulent mixing of the heavy reactant within the mixing pot. 
     
     
         9 . The method of  claim 1 , wherein the homogenizing removes concentration and temperature gradients from the heavy reactant.
