Abstract

LA INVENCION DESCRIBE UN PROCESO PARA LA PREPARACION, BAJO CONDICIONES DE REDUCCION, DE LICORES DE COCCION TENIENDO GRAN SULFATACION PARA LA COCCION DE PULPA DE SULFATO, DONDE EL LICOR NEGRO OBTENIDO EN EL PROCESO DE COCCION ES ALIMENTADO, DESPUES DE LA EVAPORACION, COMPLETA O PARCIALMENTE A UN REACTOR FUNCIONANDO A UNA TEMPERATURA ELEVADA QUE SE OBTIENE POR EL SUMINISTRO DE ENERGIA DESDE UNA FUENTE DE CALOR EXTERNA Y/O LA LIBERACION DE ENERGIA DEL LICOR NEGRO, UNA FUSION QUE CONSISTE ESENCIALMENTE EN SULFURO DE SODIO FORMADO Y EXTRAIDO PARA PROCESARLO DESPUES EN LIQUIDO DE COCCION. EL PROCESO DE ESTA INVENCION, SE CARACTERIZA EN QUE ADEMAS SE AÑADEN AL REACTOR TODOS O PARTE DE MATERIALES CONTENIENDO SULFURO Y/O CONTENIENDO SULFURO Y SODIO; PRESENTES EN EL TRITURADOR DE LA PULPA, INCLUYENDO PRODUCTOS QUIMICOS CONTENIENDO SULFURO Y/O CONTENIENDO SODIO Y SULFURO UTILIZADOS PARA EL BALANCE TOTAL DE LOS PRODUCTOS QUIMICOS DEL TRITURADOR DE PULPA, DE TAL FORMA QUE LA SAZON MOLAR DE SODIO A SULFURO EN LA MEZCLA TOTAL ADMINISTRADA AL REACTOR ESTA DENTRO DE UN MARGEN DE 1,5 A 4. DE ACUERDO CON UNA REALIZACION PREFERENTE DE LA INVENCION SE UTILIZA UNA SOLUCION ACUOSA DE LA FUSION DE SULFURO DE SODIO OBTENIDA EN LA ASI LLAMADA COCCION DE SULFATO MODIFICADA.THE INVENTION DESCRIBES A PROCESS FOR THE PREPARATION, UNDER REDUCTION CONDITIONS, OF COOKING LIQUORS HAVING GREAT SULFATATION FOR SULPHATE PULP COOKING, WHERE THE BLACK LIQUOR OBTAINED IN THE COOKING PROCESS, AFTER THE COMPLETE TO A REACTOR OPERATING AT A HIGH TEMPERATURE THAT IS OBTAINED BY THE SUPPLY OF ENERGY FROM AN EXTERNAL HEAT SOURCE AND / OR THE RELEASE OF ENERGY FROM BLACK LIQUOR, A FUSION THAT CONSISTS ESSENTIALLY OF FORMED AND REMOVED SODIUM IN PROCESSES COOKING. THE PROCESS OF THIS INVENTION IS CHARACTERIZED IN THAT FURTHER ALL OR PART OF MATERIALS CONTAINING SULFIDE AND / OR CONTAINING SULFIDE AND SODIUM ARE ADDED TO THE REACTOR; PRESENT IN THE PULP CRUSHER, INCLUDING CHEMICAL PRODUCTS CONTAINING SULFIDE AND / OR CONTAINING SODIUM AND SULFIDE USED FOR THE TOTAL BALANCE OF CHEMICAL PRODUCTS OF THE PULPA CRUSHER, LATURO MOLAR SOLAR DE LA MOLAR THE REACTOR IS WITHIN A RANGE OF 1.5 TO 4. IN ACCORDANCE WITH A PREFERRED EMBODIMENT OF THE INVENTION, A WATER-BASED SOLUTION OF THE SODIUM SULFIDE FUSION OBTAINED IN THE SO-CALLED MODIFIED SULPHATE COOKING IS USED.
