Abstract

PROCEDIMIENTO DE PRODUCCION DE UREA POR LA SINTESIS DE AMONIACO Y ANHIDRIDO CARBONICO COMPRENDIENDO UNA ETAPA DE SINTESIS A UNA PRESION DE 130-220 BARS Y UNA TEMPERATURA DE 175-200*C CON UNA RELACION MOLAR ENTRE EL AMONIACO Y EL ANHIDRIDO CARBONICO DE 3 A 5, Y DOS ETAPAS SUCESIVAS DE DESCOMPOSICION DEL CARBONATO AMONIACO NO CONVERTIDO A UREA, UNA DE LAS CUALES ES A PRESION ELEVADA Y A LA MISMA PRESION QUE EL REACTOR DE SINTESIS Y LA OTRA ES A PRESION MEDIA A 10-30 BARS, LOS PRODUCTOS DE ESAS ETAPAS DE DESCOMPOSICION SE CONDENSAN PARA RECUPERAR SU CALOR DE CONDENSACION, LA PRIMER ETAPA DE DESCOMPOSICION ISOBARA CON LA SINTESIS SE CONDUCE POR DESCOMPOSICION TERMICA CON UN AUTO-DESMONTADO SIMULTANEO MEDIANTE EL AMONIACO EN EXCESO CONTENIDO EN EL EFLUENTE DEL REACTOR DE SINTESIS Y LOS VAPORES PRODUCIDOS DESDE ESA DESCOMPOSICION; LA SEGUNDA ETAPA DE DESCOMPOSICION DEL CARBOMATO DE AMONIO SE EFECTUA EN DOS PARTES, UNA PARTE DE DESCOMPOSICION TERMICA POR CAMBIO DE CALOR -EN EL INTERCAMBI ADOR- Y UNA SEGUNDA PARTE DE DESMONTADO ADIABATICO - EN LA COLUMNA - A CONTRACORRIENTE CON PARTE DEL ANHIDRIDO CARBONICO GASEOSO ALIMENTADO A LA SINTESIS.
