Grace Expands UNIPOL® PP Technology Capacity in China by 1,550KTA

Three recent Chinese UNIPOL® PP technology start-ups will increase local onstream capacity by 25%.

Grace has expanded its UNIPOL® PP technology presence in China with three successful start-ups. These will supply 1,550 kilotons per annum (KTA) of polypropylene resin production in the Chinese market. This is a significant accomplishment for the company and its partners, as it marks a 25% increase in China onstream UNIPOL® PP technology capacity, totaling 7,800 KTA.

Over the past few years, Grace has been working closely with Dongguan Grand Resource Science & Technology Co., Ltd , PetroChina GuangDong, and one undisclosed company to expand its UNIPOL® PP technology presence in China. The result of these partnerships has led to notable milestones:  PC Guangdong’s 500 KTA plant, which is the largest single reactor line capacity in China, the doubling of Dongguan Grand Resource’s PP production from 600 KTA to 1,200 KTA, and the unannounced company joining the reactor line leaders in China with 450 KTA of polypropylene production.

All three reactor start-ups used Grace CONSISTA® catalysts, which quickly led to a polymerization reaction. The average time for reaction to occur was less than 10-minutes, with the fastest reaction achieved in just 4-minutes! Plus, all the plants were running at the design rate within 2-hours.

We are particularly proud of one polymerization reaction occurring in just 4-minutes; plus, all the plants were running at the design rate within 2-hours.

Manufacturing and Commissioning Leader

This is a remarkable accomplishment and speaks to the effectiveness of Grace's catalysts and its commitment to consistent quality.

These successful start-ups are the result of the expertise and dedication of Grace’s UNIPOL® PP Technology Team and the commissioning cooperation of the licensees. Brian Kimberley, VP of Global Licensing and Services said, “This is a testament to the pre-commissioning preparation by the start-up team, the robust simplicity of the UNIPOL® PP technology design, and the effectiveness of our catalysts. This demonstrates our commitment to innovation and quality. I am proud of the team, and we welcome the four new world-scale lines to the ever-growing family of successful UNIPOL® PP technology operators globally.”

As a leading independent supplier of polyolefin catalyst and polypropylene process technology, Grace is committed to the supply of cutting-edge technology to help our customers operate with great efficiency and sustainability in the global polypropylene market.
