Technical parameters of HDPE

In the solution reactor, the polymer is dissolved in a solvent/comonomer system. Typically, the polymer content in a solution reactor is controlled at between 10 and 30 wt-%. A hydrocarbon solvent in the range of C6 to C9 is typically used as the diluent in the solution process. 

In the recycling stage, the following purge flows are taken away from the process  

The fluidised bed reactor used for the production of LLDPE is the same as for the production of HD PE described above in Section 3.2.3.2 and is not described again. A number of fluidised bed reactor plants are designed to produce both HDPE and LLDPE according to market requirements but, in general, plants tend to operate and produce one t)q)e only. 

Catalyst Ziegler or metallocene Ziegler-Natta or metallocene
