Abstract

Представлен способ автоклавирования суспензии сырой терефталевой кислоты, полученной окислением параксилола, в процессе окисления в барботажном колонном реакторе. Способ исполняется в одном или многих барботажных колонных реакторах, имеющих одну или многие отделенные друг от друга зоны, определяемые горизонтальными перегородками, и поток частиц через систему автоклавирования контролируется для максимизации конверсии промежуточных продуктов частичного окисления в терефталевую кислоту, в то же время с минимизацией образования других загрязняющих продуктов. Температура, течение и содержание кислорода, а также другие технологические параметры и переменные характеристики оборудования контролируются на протяжении всего процесса для поддерживания образования терефталевой кислоты. Также представлены системы барботажного колонного автоклавирования, конфигурированные для исполнения способа автоклавирования.
