Basell spherizone technology

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. 

A recent development in this technology is the multizone circulating reactor (MZCR) developed by Basell ( Spherizone process), in which a given polymer particle flows back and forth between two reaction zones of a loop reactor, in each of which the conditions are different... 

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. 

Despite the success of the Spheripol process, Basell continue research aimed at improving product characteristics, widening the range of grades and developing the next generation of PP technology, the Spherizone process. 

A recent advancement in reactor technology has been the development of a fluid bed, multizone circulating reactor (MZCR) by Basell, called Spherizone.
