1. Установка для полимеризации этилена и альфа-олефина, включающая:
полимеризационный реактор, в который подают этилен и альфа-олефин в качестве реагирующих исходных веществ исходного сырья и растворители, и в котором реагирующие исходные вещества полимеризуют в состоянии раствора, для получения продукта полимеризации в виде сополимера этилена и альфа-олефина, который растворен в растворителе;
секцию разделения, включающую испарительную колонну для отделения непрореагировавших этилена и альфа-олефина, содержащихся в продукте полимеризации, в результате перегонки; и отпарную колонну для отделения низкомолекулярных олигомеров, имеющих меньшую молекулярную массу, чем у сополимера этилена и альфа-олефина, содержащегося в продукте полимеризации, в результате перегонки; и
секцию извлечения растворителя для выделения низкомолекулярных олигомеров из растворителей и низкомолекулярных олигомеров, которые выделены, а после этого для извлечения растворителей.
2. Установка по п. 1, в которой в испарительной колонне отделяют непрореагировавшие этилен и альфа-олефин, содержащиеся в продукте полимеризации, в результате мгновенной перегонки.
3. Установка по п. 1, дополнительно включающая установку промывания, установленную между испарительной колонной и отпарной колонной для дезактивирования катализатора, содержащегося в продукте полимеризации после завершения полимеризации.

отделения непрореагировавших этилена и альфа-олефина, содержащихся в продукте полимеризации, в результате перегонки;
отделения растворителей и низкомолекулярных соединений, имеющих более низкую молекулярную массу, чем у сополимера этилена и альфа-олефина и содержащихся в продукте полимеризации, в результате перегонки для получения чистого продукта полимеризации; и
отделения низкомолекулярных олигомеров от растворителей и низкомолекулярных соединений, выделенных ранее, в результате перегонки для извлечения растворителей, а после этого повторного использования извлеченных растворителей в качестве растворителей для полимеризации.
