Improvement of the obtention process of {sup 131} I of ININ through studies of equipment design and process parameters fitting in the simulator; Perfeccionamiento del proceso de obtencion del {sup 131} I del ININ mediante estudios de diseno del equipo y ajustes de parametros del proceso en el simulador

Abstract

The main objective of the work was to achieve a high yield of the reaction that happens among the vapors of {sup 131} I and the NaOH to obtain sodium iodide (Na{sup 131} I) in solution optimizing the contact time of the molecules in gaseous state of {sup 131} I with the NaOH molecules through the bubbling velocity of the {sup 131} I in the solution of NaOH 0.1 N, as well as the operation temperature during the distillation process by dry via starting from tellurium dioxide (TeO{sub 2}) with the purpose of that the {sup 131} I that is obtained in the form of Na{sup 131} I solution presents the necessary quality that allows to distribute it in the market. The particular objectives were: a) To improve the distillation equipment used for the obtaining of {sup 131} I starting from irradiated tellurium dioxide redrawing the dilution system with the purpose of recovering the {sup 131} I in a minimum volume of sodium hydroxide (NaOH). b) To achieve a bigger time of contact among the molecules of {sup 131} I in gaseous state with the molecules of NaOH in solution through the bubbling velocity and of the redrawing of the  More>>
