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 polyester polymer composition having a polyester polymer with furanic units as well as a process to prepare this polyester polymer composition are herein described. The process includes the step of reacting a cyclic polyester oligomer in the presence of a catalyst in a ring-opening polymerization reaction with a reaction temperature and a reaction time sufficient to yield a polyester polymer having furanic units. The present invention further provides a method of use of this polyester polymer composition in extrusion, injection molding, or blow molding.

摘要： A method for manufacturing poly(2-hydroxyalkanoic acid) included the steps of a) mixing a cyclic diester of a 2-hydroxyalkanoic acid and a polymerization catalyst, b) polymerizing the cyclic diester to form poly(2-hydroxyalkanoic acid) in liquid phase, c) adding a phosphoric acid ester as a catalyst deactivating agent to the liquid phase, d) applying a devolatilization step to the liquid phase, and e) allowing the poly(2-hydroxyalkanoic acid) to solidify. The catalyst deactivating agent is added after the devolatilization step is applied. The method results in an improved melt stability of the manufactured polymer.
