PROCESS AND APPARATUS FOR INDUSTRIAL FRACTIONATION OF POLYMERS |
摘要 |
In a process for industrial fractionation of polymers using an extraction column and a homogeneous extraction agent a homogeneous feed is supplied to a region of the extraction column which is nearer the upper end thereof when the feed has a greater density than the extraction agent and which is nearer the lower end thereof when the feed has a lower density than the extraction agent. An apparatus for carrying out this process consists advantageously, instead of a pulsed sieve plate column as hitherto, of an unpulsed filling body column which leads to a better separation because a back mixing is avoided in favourable manner.
