Abstract
UN SISTEMA DE DESPRESURIZACION (1) PARA DESPRESURIZAR PLANTAS, QUE OPERA CON VAPOR PRESURIZADO Y QUE INCLUYE UNA CABEZA DE VAPOR (16), MEDIANTE LA INYECCION DE AGUA FRIA BAJO LA FUERZA DE LA GRAVEDAD DESDE UN CONTENEDOR (2) LOCALIZADO A UN NIVEL MAS ELEVADO QUE LA PLANTA PRESURIZADA Y CONECTADO A LA MISMA MEDIANTE UN CONDUCTO DE ENVIO (24) QUE FORMA UN SIFON (24A,24B,24C) Y QUE ESTA CONECTADO A UNA SECCION ESTRECHA (10) DE UN EYECTOR (6) EN EL QUE FLUYE VAPOR EN EL CASO DE UN INCIDENTE, SIENDO EL VAPOR EXTRAIDO DE UN CONDENSADOR (7) LOCALIZADO EN EL FLUJO DESCENDENTE DEL EYECTOR (6), CAUSANDO UNA CAIDA EN LA PRESION QUE ATRAE AGUA FRIA DESDE EL TANQUE (2) A TRAVES DEL SIFON QUE ES DE ESTA FORMA LLENADO, PERMITIENDO QUE EL AGUA FRIA SEA INYECTADA A LA PLANTA PRESURIZADA.
