Several countries in the world have made multi-zone circulating reactors.

In March, 2009, the third polypropylene multi-zone circulating reactor in the world, the first in China and the largest in the world with a single capacity of 450,000 tons/year was born in Maoming Gravity. Maoming Gravity has become the only manufacturer of this kind of equipment in China after Italy and South Korea, filling the gap in domestic production and manufacturing of this kind of equipment. At present, the multi-zone circulating reactor has become the fist product of gravity Company. The manufacture of multi-zone circulating reactor once again provides safe and reliable equipment for national petrochemical construction.

In 20 16, the second domestic multi-zone circulating reactor of 400,000 tons/year polypropylene plant of CNOOC Huilian Phase II was successfully delivered from Maoming Gravity Petrochemical Equipment Co., Ltd. (formerly Maoming Gravity Petrochemical Machinery Manufacturing Co., Ltd.), and the multi-zone circulating reactor of Spherizone polypropylene process, which represents the world's top level, was successfully localized again, which opened the way for improving the domestic polypropylene plant capacity and product quality, and greatly reduced the material, manufacturing and transportation costs of polypropylene reactors.

From 2065438 to September 2007, the multi-zone circulating reactor of Spherizone polypropylene process, the world's top level manufactured by Maoming Gravity, was successfully localized again and exported overseas (Malaysia) for the first time, creating a milestone of "going out" of petrochemical equipment.

20 18 multi-zone circulating reactor of Zhanjiang zhongke 200,000 tons/year polypropylene plant.

20 19 The multi-zone circulating reactor of 300,000 tons/year high-performance polypropylene project of Liaoyang Petrochemical Company was completed on 20 19 and 12, and the manufacturing of multi-zone circulating reactor of Zhejiang Petrochemical Company is in progress.
