Abstract:
1. A method of producing nitrogen trifluoride, comprising: providing a reactor comprising a mixing zone and a reaction zone in fluid communication with the mixing zone; feeding gaseous fluorine into the mixing zone of the reactor; feeding liquid ammonium acid fluoride into the mixing zone of the reactor; feeding a working fluid vapor jet into the mixing zone of the reactor, wherein the working fluid vapor jet transfers kinetic energy into the mixing zone, the kinetic energy dispersing the gaseous fluorine within the liquid ammonium acid fluoride; reacting the liquid ammonium acid fluoride with the fluorine dispersed therein to produce nitrogen trifluoride as the liquid ammonium acid fluoride and fluorine pass through the reaction zone in the reactor; and removing a gaseous reaction product stream from the reactor, the reaction product stream comprising nitrogen trifluoride and the working fluid vapor.
