  • Publication number: 20130116399
    Abstract: A method for carrying out polymerization processes, includes a first step involving polymerization or co-polymerization of a monomer or monomers, and a second step involving a separation step. In an embodiment, before the separation step, during the separation step, or both before and during the separation step, one or more substance is added to the reaction mixture that induces stripping, influencing of the temperature, or both stripping and influencing of the temperature such that the reaction equilibrium is shifted to the polymers and the rate of reaction to the monomer is slowed. In embodiments, before and/or in the second step, a substance is added to the reaction mixture so that a stop is achieved, and as a further function stripping and/or influencing of temperature occurs.

  • Publication number: 20110269090
    Abstract: A device for treating a product that can be transported in a housing from an entry point to an exit point, particularly a torr factor for carrying out a roasting process utilizing a hardly flowable product forming nests and having no wall adhesion, wherein chambers are to be formed by disk-shaped elements disposed on a shaft.

  • Publication number: 20110105716
    Abstract: In a method of treating viscous products, particularly for the implementation of polymerization operations, more particularly for the homopolymerization or copolymerization of bipolymers, where monomer(s) and/or catalysts and/or initiators are fed to a backmixed mixing compound (1), in particular having a length/diameter ratio of 0.5-3.5, more particularly a process corresponding to a stirred tank cascade of 2-5 stirred tanks in series, and the product is supplied with heat and is backmixed with product that has already reacted, and the reacted product is taken off from the mixing compound (1), the product is to be heated in the mixing compound (1) up to its optimum processing temperature or boiling temperature or sublimation temperature, parts of the product are to be evaporated, and hence the exothermic heat of the product and excess mechanical introduction of heat are absorbed by evaporative cooling.
