Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA REDUCIR LOS RIESGOS DE INFLAMACION Y EXPLOSION DE LA DESCOMPOSICION DE ETILENO A ALTA PRESION. CARACTERIZADO POR MANTENER BAJO ATMOSFERA INERTE PARTE DEL DISPOSITIVO DE EVACUACION EXISTENTE ENTRE EL RECINTO A ALTA PRESION Y EL EXTERIOR, EL GAS PUEDE SER NITROGENO, DIOXIDO DE CARBONO, ETILENO, ARGON, HELIO, NEON, KRIPTON Y XENON, A UNA PRESION DE EVACUACION INFERIOR O IGUAL A 1,5 BARES; PARA LO CUAL HACE USO DE UN DISPOSITIVO QUE TIENE UN MECANISMO DE OBTENCION SOBRE EL CAMINO (1) DE EVACUACION DE LOS GASES, UN PRIMER CIRCUITO DE DISTRIBUCION (7) DE GAS UNIDO POR UN CONDUCTO AL CONDUCTO DE EVACUACION SITUADO ENTRE EL ORGANO DE PROTECCION Y EL MECANISMO DE OBTURACION Y UN SEGUNDO CIRCUITO DE DISTRIBUCION DEL GAS UNIDO POR UN CONDUCTO AL MECANISMO DE OBTURACION Y MEDIOS DE ADMISION DEL GAS SOBRE DICHO CONDUCTO PARA CONTROLAR EL VOLUMEN DE GAS ENTREGADO POR EL SEGUNDO CIRCUITO.
