Description
Известен способ осуществлени нроцесса ненрерывной полимеризации этилена в двухзональном трубчатом полимеризаторе с диаметром труб 10 мм в полимеризационной зоне и 16 мм в последующей зоне (см. реферат фирмы И. Г. Фарбениндустри от 15 феврал 1943 г.).The known method of implementing the process of continuous polymerization of ethylene in a two-zone tubular polymerizer with a pipe diameter of 10 mm in the polymerization zone and 16 mm in the subsequent zone (see the abstract of the company IG Farbenindustry from February 15, 1943).
Известно также применение в отечественной промышленности двухзональных трубчатых аппаратов с диаметром труб 16 мм и 24 мм. Однако в указанных аппаратах процесс протекает очень энергично и управление ими представл ет р д трудностей, так как не обеспечиваетс разграничение ведени процесса по фазам: нагревани , полимеризации и отвода тепла.It is also known the use in the domestic industry of two-zone tubular apparatus with a pipe diameter of 16 mm and 24 mm. However, in these devices, the process proceeds very vigorously and their management presents a number of difficulties, since there is no separation of the process by phase: heating, polymerization, and heat removal.
Предлагаемый способ получени полиэтилена и аппарат дл его осуществлени отличаютс тем, что полимеризацию этилена провод т в трехзональном трубчатом аппарате при температуре реакционного пространства 160-190° и давлении 1300-1500 атм. Аппарат состоит из трех зон, служащих соответственно дл нагревани полиэтилена, его полимеризации и отвода тепла процесса полимеризации, снабженных секци ми трубок диаметром: перва - Ш мм, втора - 16 мм и треть - 24 мм.The proposed method of producing polyethylene and the apparatus for its implementation are characterized in that the polymerization of ethylene is carried out in a three-zone tubular apparatus at a temperature of the reaction space of 160-190 ° and a pressure of 1300-1500 atm. The apparatus consists of three zones serving respectively for heating polyethylene, its polymerization and heat removal of the polymerization process, supplied with tube sections with diameters: first - Ø mm, second - 16 mm and third - 24 mm.
Проведение процесса в трехзональном трубчатом полимеризаторе по сравнению с двухзональным трубчатым полимеризатором имеет р д преимуществ: процесс полимеризации протекает в основном в трубках диаметром 10 и 16 мм вместо трубок диаметром 16 и 24 мм, т. е. в более спокойных услови х, что дает возможность повысить давление до 1300-1500 атм и понизить температуру до 160-190°; улучшаетс управление процессом, снижаютс расходные коэффициенты по сырью и повышаетс производительность полимеризатора; повышаетс качество полиэтилена за счет проведени процесса при более низкой температуре и повышенном давлении.The process in a three-zone tubular polymerization unit has several advantages compared with a two-zone tubular polymerization agent: the polymerization process takes place mainly in tubes with a diameter of 10 and 16 mm instead of tubes with a diameter of 16 and 24 mm, i.e., in calmer conditions, which makes it possible increase the pressure to 1300-1500 atm and lower the temperature to 160-190 °; process control is improved, raw materials consumption ratios are reduced and polymerizer productivity is improved; The quality of polyethylene is improved by carrying out the process at a lower temperature and elevated pressure.
№ 125381- 2 На чертеже изображен схематически трехзональный трубчатый полимеризатор .No. 125381-2 In the drawing, a three-zone tubular polymerizer is shown schematically.
Перва Р состоит из трех трубок 1, 2 и 3 диаметром 10 мм и длиною рколю 4 м кажда и предназначена дл предварительного нагревани и начала полимеризации этилена. Втора зона состоит из восьми трубок 4, 5, 6, 7, 8, 9., 10 и // диаметром 16 мм и длиною около 2 м кажда и служит дл проведени процесса полимеризации. The first P consists of three tubes 1, 2 and 3 with a diameter of 10 mm and a length of 4 meters each, and is intended to preheat and initiate the polymerization of ethylene. The second zone consists of eight tubes 4, 5, 6, 7, 8, 9., 10 and // with a diameter of 16 mm and a length of about 2 meters each and serves to carry out the polymerization process.
Треть зона состоит из восьми трубок 12, 13, 44, 15, 16, 17, 18 и 19 диаметром 24 мм и длиною около 2 .и кажда и служит дл торможени процесса полимеризации.The third zone consists of eight tubes 12, 13, 44, 15, 16, 17, 18 and 19 with a diameter of 24 mm and a length of about 2. And each and serves to slow down the polymerization process.
