Abstract
CON UN PROCEDIMIENTO PARA LA OBTENCION DE ACIDO NITRICO SEGUN EL PROCEDIMIENTO DE DOS PRESIONES, EN EL QUE LA COMBUSTION DEL AMONIACO UTILIZADO EN LA PRIMERA PRESION QUE ES BAJA SE REALIZA MEDIANTE AIRE COMPRIMIDO PROCEDENTE DEL PROCESO, Y EN EL QUE LA COMBUSTION DEL GAS NITROSO FORMADO A UNA SEGUNDA PRESION QUE ES MAS ALTA QUE LA PRIMERA, SE ABSORBE AL MENOS PARCIALMENTE CON AGUA, POR LO QUE EL ACIDO NITRICO SE FORMA, Y EL GAS QUE NO HA SIDO ABSORBIDO CON OBJETO DE UNA RECUPERACION DEL TRABAJO DE LA COMPRESION SE DESCOMPRIME EN UN EXPANSOR DE GAS DESDE LA SEGUNDA PRESION A LA PRESION AMBIENTAL; SE DEBE PREPARAR UNA DISOLUCION, CON LA CUAL SE CONSIGA UNA OPTIMIZACION DE LA OBTENCION DEL ACIDO NITRICO, CON MEJORA DE LOS PARAMETROS DE LA PRODUCCION Y DE LOS RENDIMIENTOS DE MATERIA Y ENERGIA. ESTO SE CONSIGUE, PORQUE SE HACE FUNCIONAR UN TURBOCOMPRESOR DE TRANSMISION DE VARIAS LONGITUDES DE ONDA SEPARADO DEL AIRE DEL PROCESO Y DEL GAS NITROSO, COMPRIMIENDO EL AIRE DEL PROCESO A LA CITADA PRIMERA PRESION, Y COMPRIMIENDO EL GAS NITROSO A LA CITADA SEGUNDA PRESION.
