Abstract

PROCESO PARA LA ELIMINACION DE OXIDOS DE AZUFRE A PARTIR DE GAS QUE CONTIENE OXIDO DE AZUFRE CON PRODUCCION SIMULTANEA DE SULFATO AMONICO. EL PROCESO SE REALIZA PASANDO PRIMERO GAS MUY CALIENTE QUE CONTIENE OXIDO DE AZUFRE A TRAVES DE UN PRE-LAVADOR EN DONDE EL GAS CONTACTA CON LICOR DE SULFATO AMONICO ACUOSO SATURADO EL CUAL ES RECICLADO EN EL PRE-LAVADOR (10), SEGUIDO POR PASAR EL GAS PRELAVADO A TRAVES DE UN ABSORBEDOR (40) EN DONDE EL GAS PRELAVADO CONTACTA LICOR DE SULFATO AMONICO ACUOSO DILUIDO. EL OXIDO DE AZUFRE DEL GAS QUE CONTIENE OXIDO DE AZUFRE ES ABSORBIDO POR EL LICOR (48) DE SULFATO AMONICO ACUOSO DILUIDO EN EL ABSORBEDOR, Y GAS LAVADO SE RETIRA DEL ABSORBEDOR. EL LICOR DE SULFATO AMONICO ACUOSO DILUIDO SE TRATA CON AMONIACO (58) Y AIRE (82) Y EL DIOXIDO DE AZUFRE ABSORBIDO SE CONVIERTE A SULFATO AMONICO EN EL LICOR. EL LICOR DE SULFATO AMONICO DILUIDO ES RECICLADO EN CONTACTO CON EL GAS PRELAVADO EN EL ABSORBEDOR. LICOR DE SULFATO AMONICO ACUOSO DILUIDO ES ELIMINADO DEL ABSORBEDOR Y AÑADIDO AL LICOR (34) DE SULFATO AMONICO ACUOSO SATURADO EN EL PRE-LAVADOR, DONDE SE VUELVE SATURADO DEBIDO A EVAPORACION CAUSADA POR EL GAS ARDIENTE. FORMAS DE CRISTALES DE SULFATO AMONICO DEL LICOR DE SULFATO AMONICO SATURADO DEL PRE-LAVADOR SE RECUPERAN COMO PRODUCTO (126) DEL SULFATO AMONICO ACUOSO SATURADO EXTRAIDO DEL PRE-LAVADOR.
