Process for the reduction or elimination of NH3/HF byproduct in the manufacture of nitrogen trifluoride
A process for reducing or eliminating NH3/HF/MFz liquid waste melt in the manufacture of NF3 is provided which includes the steps of providing an NF3 reactor for a reaction of F2 with a liquid NH3/HF/MFz mixture that produces NF3, HF, N2 and other nitrogen fluorides as gaseous products and a liquid...

| Abstract | A process for reducing or eliminating NH3/HF/MFz liquid waste melt in the manufacture of NF3 is provided which includes the steps of providing an NF3 reactor for a reaction of F2 with a liquid NH3/HF/MFz mixture that produces NF3, HF, N2 and other nitrogen fluorides as gaseous products and a liquid NH3/HF/MFz mixture as the liquid waste melt. The process further provides for reduction or elimination of the liquid NH3/HF/MFz waste melt produced by the reactor. |
