    Abstract: A static devolatilisation apparatus (1) adapted for devolatilising a viscous liquid (2) comprising a volatile component is disclosed. The apparatus (1) comprises a phase separation chamber (100) in an upper region (5) for treating the viscous liquid (2) in a first devolatilisation step to form a first devolatilised viscous liquid (21), and a distributor sub-unit 200 is located below the phase separation chamber (100) and above a lower sump region (4). The sub-unit (200) has a second discharge region (222) embodied such that it is contacted by the first devolatilised viscous liquid (21), and the region (222) has a surface (223) embodied such that the first devolatilised viscous liquid (21) is treated in a second devolatilisation step. The present invention further relates to a process to devolatilising a viscous liquid using the apparatus (1) and also to the use of the apparatus (1) in the devolatilisation of polymer melt or solution.

    Abstract translation: 公开了一种适于使包含挥发性组分的粘性液体(2)脱挥发分的静态脱挥发分装置(1)。 装置(1)包括在上部区域(5)中的相分离室(100),用于在第一脱挥发分步骤中处理粘性液体(2)以形成第一脱挥发分粘性液体(21)和分配器子单元 200位于相分离室(100)下方和下部集水区(4)的上方。 子单元(200)具有第二排放区域(222),其被实施为使得其与第一脱挥发分的粘性液体(21)接触,并且区域(222)具有表面(223),使得第一脱挥发粘的粘性 在第二脱挥发分步骤中处理液体(21)。 本发明还涉及使用该装置(1)使粘性液体脱挥发分的方法,还涉及在聚合物熔体或溶液的脱挥发分中使用该装置(1)。
