REACTOR TRAYS FOR A VERTICAL STAGED POLYCONDENSATION REACTOR

摘要

This invention relates to a vertically disposed polymerization reactor (2) having a series of essentially circular tray assemblies (10); each tray assembly (10) having a central open vapor chimny (18) and a single flow path (26) composed of at least two loops (30, 32) wherein the liquid polymer flow is reversed by means of a substantially semi-circular turnaround wall (24); said trays havig a liquid polymer tray inlet (14) and a liquid polymer tray oudet (16) for conducting a flow of the liquid polymer by means of a hydraulic gradient; each tray assembly (10) being open at the top for escape of vapor from thG liquid polymer flow to the central open vapor chimny (18),and said trays (10) arranged vertical disposition one above the other.
