Abstract

В заявке описано устройство и способ полимеризации этилена при высоком давлении, по желанию, в присутствии одного и более сомономеров, в котором непрореагировавший мономер отделяется от полимера в системе разделения, включающей по меньшей мере первый, второй и третий разделительные сосуды, и в котором газ, отходящий от второго сосуда, подлежит повторному объединению с продуктовой смесью в месте, располагаемом до первого разделительного сосуда, предпочтительно при использовании насоса-эжектора.
