摘要： A vapor-liquid contact tray apparatus includes a tray having a plurality of apertures for passage of fluid through the tray. The apertures are arranged in a first group of three adjacent rows extending substantially parallel to a main liquid flow path of the tray. Apertures of the middle row are offset along the main liquid flow path on the tray from adjacent apertures of the other two rows to form a triangular pattern of adjacent apertures across the three adjacent rows. The apertures have a length and a width, each length is oriented substantially parallel to its row and each width is oriented substantially perpendicular to its row. Centers of adjacent apertures within each row are separated by a first spacing which is equal to or between 2.5 and 4.5 times the average length of the apertures in that row. Adjacent rows are separated by a second spacing which is equal to or between 1.5 and 2.5 times the average width of the apertures of the adjacent rows.

摘要： 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.
