Abstract

Головная часть колонны содержит боковые проточные трубки, расположенные в параллельной конфигурации. Эти боковые проточные трубки входят в головную часть колонны через чередующиеся отверстия в головной части колонны, так что на каждую боковую проточную трубку приходится только одно отверстие в головной части колонны. Каждая из боковых проточных трубок содержит перфорированную секцию, расположенную внутри головной части колонны и имеющую некруглое поперечное сечение, при этом это некруглое поперечное сечение имеет форму кругового сектора, эллиптического сектора или неправильного четырехугольника. Способ содержит пропускание расплавленного полимера через боковые проточные трубки в головной части колонны. Расплавленный полимер выходит из боковых проточных трубок внутри головной части колонны. Способ содержит получение дегазированного полимера.
