Patent number: 7850926Abstract: 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.Type: GrantFiled: January 8, 2001Date of Patent: December 14, 2010Assignee: Lurgi Zimmer GmbHInventors: Fritz Wilhelm, Ferdinand Finkeldei

Publication number: 20090192285Abstract: 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.Type: ApplicationFiled: December 14, 2004Publication date: July 30, 2009Inventors: Fritz Wilhelm, Stefan Deiss
