Abstract
EN UN PROCEIMIENTO PARA LA PREPARACION DE ACIDO NITRICO MEDIANTE OXIDACION Y ABSORCION DE UNA CORRIENTE GASEOSA JUNTO CON OXIDO DE N QUE CONTIENE O (NO2) EN UNA SOLUCION ACUOSA EN UN DISPOSITIVO DE CONTACTO DEL FLUIDO GASEOSO EN CONTRA DE LA CORRIENTE POR GRANDES OXIDACIONES COMO ABSORCION DE VOLUMEN, SE CONSIGUE, CON AQUELLA RICA EN LIBERACION DE GAS CON AGENTES EFECTIVOS Y SIMPLES. SE CONSIGUE POR ELLO QUE EL PROCEDIMIENTO SE LLEVA A CABO POR UN CONTENIDO DE VOLUMEN DE ABSORCION - OXIDACION MAYOR QUE 25, EN SU CASO 30.
