Patent

CA 2188878

This invention relates to a ver- tically disposed polymerization reactor (2) having a series of essentially circu- lar tray assemblies (10); each tray as- sembly (10) having a central open va- por chimney (18) and two split-flow paths (26) each split-flow path (26) con- taining one reverse flow path wherein the liquid polymer flow is reversed by means of a substantially semi-circular turnaround region (24); said trays (10) having a liquid polymer tray inlet (14) and a liquid polymer tray outlet (16) for conducting a flow of the liquid polymer by means of a hyraulic gradient; each tray assembly (10) being open at the top for escape of vapor from the liquid polymer flow to the central open vapor chimney (18); and said trays (10) ar- ranged in vertical disposition one above the other.

Réacteur (2) de polymérisation disposé verticalement qui possède une série d'ensembles plateaux (10) essentiellement circulaires. Chaque ensemble plateau (10) est pourvu d'une cheminée (18) à vapeur centrale ouverte et de deux passages (26) à flux divisé, chaque passage (26) à flux divisé contenant un passage de flux inversé, le flux de polymère liquide étant inversé à l'aide d'une région (24) de changement de sens sensiblement semi-circulaire. Lesdits plateaux (10) possèdent un orifice d'entrée (14) de polymère liquide et un orifice de sortie (16) de polymère liquide permettant d'acheminer un flux de polymère liquide à l'aide d'un gradient hydraulique. Chaque ensemble plateau (10) est ouvert dans sa partie supérieure pour que la vapeur puisse s'échapper du flux de polymère liquide vers la cheminée (18) à vapeur centrale ouverte. Lesdits plateaux (10) sont disposés verticalement les uns au-dessus des autres.
