A Single-step Solution for PTA Production
How to Lower OPEX Without Compromising on Quality
This paper looks at how the earlier PTA production method involving a multi-stage process with pressure and atmospheric centrifuges and a re-slurry tank can be replaced with one stand-alone device – the rotary pressure filter (RPF).
The paper looks in detail at the design, operating principle, and performance of a state-of-the-art RPF. Two reference projects from Indonesia and Russia show how the right separation technology can deliver low OPEX while maintaining the same quality, enabling PTA producers to remain competitive even when prices fluctuate. This paper shows also that switching over to a single RPF process can also be the right option for existing plants looking to future-proof their business by cutting costs without compromising on the quality of their product.
