METHOD FOR DRYING A WET POLYMER

摘要

The claimed invention relates to a method for drying a wet polymer and an apparatus therefor. The method is characterised in that the wet polymer is dried in a dryer containing at least one heating element in which a heat-transfer fluid flows, the said heat -transfer fluid being low-pressure steam at an absolute pressure lower than 4 bar. The Apparatus comprising at least one dryer equipped with at least one heating element and a means for supplying the heating element with low- pressure steam at an absolute pressure lower than 4 bar; an ejector for sucking out the condensates produced by the condensation of the steam downstream of the dryer, a tank for collecting the condensates issuing from the ejector. The invention provides increasing the heat transfer coefficient and causes the polymer to stagnate and deteriorate in the heating elements.
