Abstract

В заявке описаны способ и устройство для возврата мелочи в прокачиваемую через циркуляционный реактор полимеризационную суспензию, которые могут быть использованы в процессе суспензионной полимеризации в жидкой среде, содержащей инертный разбавитель и неполимеризованные мономеры. Устройство имеет соединенный с реактором (1) выпускной клапан (8В) для отбора из него части суспензии в трубопровод (9), по которому отобранная суспензия поступает в выпарной аппарат (11) мгновенного действия, где часть суспензии превращается в первую жидкость, содержащую разбавитель и мелочь, которая по трубопроводу (12) направляется в циклонный сепаратор (13), где часть первой жидкости превращается во вторую жидкость, содержащую разбавитель и мелочь, которая по трубопроводу (22) попадает в теплообменник (23Е), где вторая жидкость превращается в жидкость, содержащую разбавитель и мелочь, которая направляется по трубопроводу (22А) в прокачиваемую через реактор (1) полимеризационную суспензию.Международная заявка была опубликована вместе с отчетом о международном поиске.
