Abstract
Esta invención proporciona un proceso mejorado para recuperar ácidocítrico a partir de una corriente de proceso impura tal como caldo defermentación, por la adición de un ácido fuerte o sus sales, a unasolución concentrada del ácido cítrico. El proceso proporcionaesencialmente una etapa de purificación, sin los problemas de desechos dedesperdicio o gran inversión de capital requerida ya sea por los procesosde recuperación con extracción de solvente o cal-sulfúrico. Larecuperación puede mejorarse adicionalmente a tratara el licor madre quequeda después su separación de los cristales de ácido cítrico para obtenerun rendimiento adicional. El ácido fuerte preferido es ácido sulfúrico yel tratamiento del licor madre preferido es una columna de resina conexclusión de iones. Mientras que el proceso mejorado es particularmenteventajoso cuando se emplea como un proceso de purificación de una etapapara ácido cítrico, debidamente el caldo de fermentación, puede emplearseen conjunto con las diversas corrientes de proceso impuras generadas porel proceso de recuperación por extracción con solvente o de cal-sulfúrico.
