PROCESS FOR TREATING A POLYOLEFIN DISCHARGED FROM AN OLEFIN POLYMERIZATION REACTOR |
摘要 |
<p>Process for treating polyolefin discharged from an olefin polymerization reactor which comprises steps of discharging from a polymerisation reactor a slurry comprising polyolefin and diluent,' submitting said slurry to a pressure release such that the diluent is evaporated and a polyolefin/gas mixture is formed; discharging said polyolefin/gas mixture into a collecting vessel; controlling a level of settled polyolefin in the collecting vessel; discontinuously transferring the polyolefin/gas Mixture in the collecting vessel into a concentrating vessel :, and discharging said concentrator vessel in such a way that said polyolefin/gas mixture is transferred into the hydrocarbon purge bin. Embodiments also comprise the use of two interconnected concentrator vessels and the optimized recovery of the diluent from the purge bin.</p> |
