System and method for vaporizing a cryogenic liquid

Abstract

A flameless thermal oxidizer including a matrix bed containing media and an inlet tube extending into the matrix bed and having an outlet positioned to deliver reacting gases into the matrix bed is disclosed. The matrix bed defines a void proximal the outlet of the inlet tube. Also disclosed is a method of reducing pressure losses in a flameless thermal oxidizer including the step of introducing reacting gases from an inlet tube into a void defined by a matrix bed.

1 . A flameless thermal oxidizer comprising:
 a matrix bed containing media; and   an inlet tube extending into said matrix bed and having an outlet positioned to deliver reacting gases into said matrix bed;   said matrix bed defining a void proximal said outlet of said inlet tube.   
   
   
       2 . The flameless thermal oxidizer of  claim 1 , further comprising a disc positioned adjacent said outlet of said inlet tube and configured to direct reacting gases away from said inlet tube. 
   
   
       3 . The flameless thermal oxidizer of  claim 1 , said void being substantially cylindrical. 
   
   
       4 . A method of reducing pressure losses in a flameless thermal oxidizer comprising introducing reacting gases from an inlet tube into a void defined by a matrix bed. 
   
   
       5 . The method of  claim 4 , wherein the introducing step comprises introducing gases from an inlet tube into a cylindrical void defined by the matrix bed. 
   
   
       6 . The method of  claim 4  further comprising the step of directing reacting gases away from said inlet tube by a disc positioned adjacent the outlet of the inlet tube. 
   
   
       7 . A flameless thermal oxidizer that is configured for reducing pressure loss of reacting gases comprising:
 a matrix bed containing media; and   an inlet tube extending into said matrix bed and having an outlet positioned to deliver reacting gases into said matrix bed; and   a disc positioned adjacent said outlet of said inlet tube and configured to direct reacting gases away from said inlet tube;   said matrix bed defining a void proximal said outlet of said inlet tube that is substantially devoid of media, wherein said outlet of said inlet tube is positioned to deliver reacting gases into said void defined in said matrix bed in order to lower pressure losses of the reacting gases in the flameless thermal oxidizer.   
   
   
       8 . The flameless thermal oxidizer of  claim 7  said void being substantially cylindrical. 
   
   
       9 . The flameless thermal oxidizer of  claim 8  wherein a ratio of a diameter dimension of said substantially cylindrical void to a depth dimension of said substantially cylindrical void is about 8:3. 
   
   
       10 . The flameless thermal oxidizer of  claim 8  wherein a ratio of a diameter dimension of said substantially cylindrical void to a depth dimension of said substantially cylindrical void is at least about 8:3. 
   
   
       11 . The flameless thermal oxidizer of  claim 8  wherein a ratio of a depth dimension of said substantially cylindrical void to a diameter dimension of said substantially cylindrical void is at least about 3:8. 
   
   
       12 . The flameless thermal oxidizer of  claim 7  wherein said void is bounded by media and said outlet of said inlet tube. 
   
   
       13 . The flameless thermal oxidizer of  claim 7 , said inlet tube having an inlet for receiving a fuel and air mixture, wherein said inlet is disposed opposite said outlet of said inlet tube and said inlet is positioned outside of said matrix bed.
