China Prosperity’s second PTA line incorporates Invista’s E2R, Solvent Interchange and R2R technologies, further enhancing the competitiveness of the technology for 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.
Invista PTA technology is available as a license package from its Performance Technologies unit.
