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.A method for producing oxygen by adsorption at a variable pressure is proposed, which includes one or several stages of a given treatment. For each stage of a given treatment, a given treatment is carried out in each tower of the oxygen production system and several neighboring towers on both sides of the tower. The method allows to increase the degree of oxygen reduction upon receipt of oxygen by adsorption at variable pressure.
