Abstract

La invención es un método y un diseño de planta de 5 ácido sulfúrico para la reducción de emisiones de arranque de SO2, SO3 y H2SO4 en la producción de ácido sulfúrico, en la cual el SO2 se convierte a SO3 en n lechos de catalizador sucesivos, donde n es un número entero > 1. Los lechos catalíticos finales se utilizan como absorbentes para SO2 a SO3 durante el 10 procedimiento de arranque, y uno o más de los m lechos corriente abajo del primer lecho son purgados, ya sea por separado o simultáneamente, con gas caliente, donde m es un número entero > 1 y m < n, durante la detención previa. También, una purga separada con gas caliente se utiliza en el lecho final.
