Multi-zone circulating reactor MZCR

Description The Spherizone process is Basell s new proprietary gas-loop reactor technology based on a Multi-Zone Circulating Reactor (MZCR) concept. Inside the reactor (1) the growing polymeric granule is continuously recirculating between two interrelated zones, where two distinct and different fluodynamic regimes are realized. 

The development of the Spherizone technology started in 1995 and was subsequently scaled up from pilot plant to commercial size in 2002, when the new multi-zone circulating reactor (MZCR) was installed at Basell s plant in Brindisi, Italy.
