Abstract
1.- Un proceso para la elaboración de un producto compuesto por sulfato de calcio hemihidrato alfa y sulfato de calcio hemihidratado beta conformado por los siguientes pasos: alimentar una mezcla de yeso de 50-75% de peso en un primer reactor, estando tal mezcla compuesta de sulfato de calcio dihidratado y agua; calcinar la mezcla en el reactor en condiciones suficientes para formar una mezcla parcialmente calcinada compuesta de agua, sulfato de calcio dihidratado y sulfato de calcio hemihidratado alfa, donde la mezcla se mantiene en el primer reactor en condiciones para calcinar el yeso y convertir el 50 a 95% del mismo en sulfato de calcio hemihidratado alfa; deshidratar la mezcla parcialmente calcinada para formar una corriente de agua y sólidos deshidratados compuestos por el sulfato de calcio dihidratado y sulfato de calcio hemihidratado alfa; alimentar los sólidos deshidratados en un segundo reactor; y calcinar los sólidos deshidratados en un segundo reactor para convertir por lo menos parte del sulfato de calcio dihidratado de los sólidos deshidratados en sulfato de calcio hemihidratado beta. 2.- El proceso de la reivindicación 1, donde la mezcla se mantiene en el primer reactor en condiciones para calcinar el yeso y convertir el 80 a 95% del mismo en sulfato de calcio hemihidratado alfa. 3.- El proceso de la reivindicación 1, donde la mezcla se mantiene en el primer reactor en condiciones para calcinar el yeso y convertir el 70 a 85% del mismo en sulfato de calcio hemihidratado alfa. 4.- El proceso de la reivindicación 1, donde por lo menos un modificante de cristal y agua son añadidos al sulfato de calcio dihidratado antes de dicha calcinación en el primer reactor. 5.- El proceso de la reivindicación 1, donde el primer reactor es un reactor de tanque de mezcla continua (CSTR). 6.- El proceso de la reivindicación 1, donde el primer reactor opera a una presión de 15 a 100 psig durante la calcinación en el primer reactor.
