Abstract

Предлагается способ получения кислорода адсорбцией при переменном давлении, включающий одну или несколько стадий заданной обработки. Для каждой стадии заданной обработки заданную обработку выполняют в каждой башне системы получения кислорода и нескольких соседних башнях по обе стороны башни. Способ позволяет увеличить степень восстановления кислорода при получении кислорода адсорбцией при переменном давлении.
