W.R. Grace & Co (Grace; Columbia, Md.) announced the successful start-up of several polypropylene (PP) reactor lines in China.
Dongguan Grand Resource Science & Technology Co., Ltd. (Dongguan Grand Resource) started up its second plant (consisting of two reactor lines) for using Grace’s UNIPOL PP Technology and will add 600,000 metric tons per year (m.t./yr) of polypropylene resin capacity and increase its total nameplate capacity to 1,200 (m.t./yr). In addition, Dongguan Grand Resource is utilizing Grace’s CONSISTA catalysts in both of its UNIPOL PP technology lines.
Grace has also started up a 500,000-m.t./yr reactor line for PetroChina GuangDong PetroChemical Company (PetroChina GuangDong), a subsidiary of PetroChina Group, the world’s second-largest petroleum company. The plant will produce homopolymer, random copolymer, and impact copolymer polypropylene resins, catering to the growing demand for high-quality PP resins in the Chinese market. This marks the fourth UNIPOL®PP technology plant start-up for PetroChina, which includes PetroChina Guangxi (200,000-m.t./yr), PetroChina Fushun (300 KTA), and PetroChina Sichuan (450,000-m.t./yr). In China, this is the largest UNIPOL PP technology single-extruder reactor line.
Furthermore, Grace has signed a new license with PetroChina Guangxi Petrochemical Company (PetroChina Guangxi) to develop a 400,000-m.t./yr single reactor line using its UNIPOL® PP technology. The anticipated start up is in 202
