Split flow reactor trays for vertical staged polycondensation reactors

摘要

This invention relates to a vertically disposed polymerization reactor having a series of essentially circular tray assemblies; each tray assembly having a central open vapor chimney and two split-flow paths each split-flow path containing one reverse flow path wherein the liquid polymer flow is reversed by means of a substantially semi-circular turnaround region; each tray having a liquid polymer tray inlet and a liquid polymer tray outlet for conducting a flow of the liquid polymer by means of a hydraulic gradient; each tray assembly being open at the top for escape of vapor from the liquid polymer flow to the central open vapor chimney; and each tray arranged in vertical disposition one above the other.
