China Prosperity Applies PTA Technology from Invista

Invista Performance Technologies (IPT) and China Prosperity (also referred to as Hanbang Petrochemical) announced successful start-up of China Prosperity’s second PTA line.

Shanghai/China – China Prosperity’s second PTA line incorporates Invista’s E2R, Solvent Interchange and R2R technologies, further enhancing the competitiveness of the technology in terms of capital productivity, variable cost and environmental performance.

The Solvent Interchange technology, which has inherently low capital cost, has been successfully deployed with additional advantages achieved through the use of locally manufactured rotary pressure filters.

Li Xing, chairman of China Prosperity, expressed his trust in this PTA technology, saying, “The successful start-up of China Prosperity’s second line demonstrated the advancement of Invista’s technology. Congratulations to both teams on the achievement of on-spec product within 24 hours of start-up. We look forward to long-term cooperation with Invista. We will rectify the defects in the ancillary facilities and restart the plant as soon as possible.”

Mike Pickens, IPT president, commented, “The successful start-up of China Prosperity’s second line again demonstrates our capabilities in the areas of PTA technology development, engineering, licensee support services and commissioning. We are proud of this accomplishment and at the same time, I am appreciative of the trust that Chairman Li Xing and his team have placed on us, recognizing that selection of industry leading technology is critical for a good return on investment.”

China Prosperity continues to operate another Invista PTA line on the same site and is constructing a polyester resin plant utilizing the company's technology.
