  • Patent number: 8017717
    Abstract: Polyesters such as polyethylene, polypropylene and polybutylene terephthalate are made from melts of precondensates of polyesters by first conducting vapors comprising precondensate components distributed in the form of an aerosol through a polycondensation reactor in which precondensate components are deposited on the reactor wall and in an outlet chamber of the reactor on a separator. Then the deposits are conducted to the unstirred discharge sump. Upper layers of the discharge sump are continuously recirculated in the stirred reactor area and thus subjected to reconversion and further polycondensation.

  • Patent number: 7850926
    Abstract: A process for the discontinuous production of granules from polycondensation polymers by precondensation of an oligomer at 5 to 400 mbar and subsequent polycondensation in a stirring reactor and subsequent granulation. In the vicinity of the outlet port, the density of the entraining surfaces lies between 1 and 8 m2 per m3 reactor space and constantly increases with increasing distance from the discharge region. Inside the reactor, there is a viscosity gradient between the region most remote from the discharge port and the zone of the discharge port. The thermal decomposition of the polymer melt flowing out of the reactor is compensated during granulation. The stirring reactor with horizontal longitudinal axis approximately has the shape of a single or double truncated cone. The reactor has rotatable, vertical product entraining surfaces and stationary scrapers between the same.

  • Publication number: 20090192285
    Abstract: Disclosed is a method for producing polyesters by means of esterification or re-esterification, precondensation of the esterified/re-esterified product, and polycondensation of the precondensed product at a pressure of 0.2 to 500 mbar and a temperature of 230 to 330° C. According to said method, the vapors formed during precondensation and polycondensation are condensed and the obtained cooled diol is redirected into the condensation stage. In order to improve the degree of separation, the vapors are directed into a bottomless direct contact condenser, the base of which is immersed into the top funnel-shaped section of a barometrically dipped downpipe so as to form an annular space, cooled diol is sprayed into the vapors in the top section of the direct contact condenser, the remaining vapors are recovered via the annular space, and the formed polymer aggregates are removed.

  • Publication number: 20060030727
    Abstract: In a method for the continuous pre-polycondensation of esterification/transesterification products the stream freely passes from top to bottom in a vertical reaction apparatus through a plurality of attached, heatable, sloped open-above bases, through product overflow channels connected with each other. In order to be able to set a determined, efficient as possible product level in the channels, the esterification/transesterification products are fed though closed, annular-type, concentric annular channels or through parallel channels, wherein a partial quantity of the product stream flowing in the channel is discharged at the product overflows and the remaining product stream is passed via drainage openings.
