Abstract
PROCEDIMIENTO PARA TRATAR POR OXIDACION UN CONDENSADO PROCEDENTE DE INSTALACIONES DE PRODUCCION DE UREA. SE CALIENTA EL CONDENSADO A UNA TEMPERATURA SUPERIOR A 60 C Y SE AJUSTA EL PH A UN VALOR SUPERIOR A 9, MEDIANTE POR EJEMPLO LEJIA DE SOSA. SE EFECTUA LA OXIDACION POR MEDIO DE CLORO, OZONO O HIPOBROMITO MIENTRAS QUE SE CONTROLA EL VALOR DEL PH Y EVENTUALMENTE SE REALIZA UNA APORTACION ADICIONAL DE LEJIA DE SOSA PARA ESTABILIZARLO EN UN VALOR SUPERIOR A 9. SE ENFRIA EL CONDENSADO OXIDADO DEL PROCESO A MENOS DE 70 C POR MEDIO DE UN INTERCAMBIO DE CALOR, SE FILTRA POR MEDIO DE CARBON ACTIVO Y SE DESALINIZA EN UNA INSTALACION DE INTERCAMBIO IONICO, TAL COMO UN FILTRO DE LECHO MIXTO.
