The catalyst is designed for use as customized layers in tubular reactors, wherein the layer system ensures an early, stabilized hotspot, resulting in long catalyst lifetime. Furthermore, Clariant offers expert support for catalyst loading and start-up, as well as for performance optimization during the entire catalyst lifetime.
Petrowidada is one of the largest producers of phthalic anhydride in Southeast Asia and the sole producer in Indonesia. The company’s world-class plant in East Java has successfully used previous generations of Clariant’s high-ortho-xylene-load PA catalysts since 2007. With OxyMax PA 690, the facility has experienced an increase in overall plant yield of 1 wt.%, and benefits from excellent PA quality with low impurity levels at the reactor outlet. Considering the plant’s annual capacity of 70,000 metric tons of phthalic anhydride, the superior productivity afforded by the new catalyst translates into considerable benefits for the producer.
Mr. Jaka Lelana, Plant Director at Petrowidada, expressed his satisfaction with the new catalyst, stating, “Given the scale of our phthalic anhydride business, efficiency is key to our continued success. That’s why we are particularly enthusiastic about the performance of the new catalyst, and confident that it will open new avenues for growth.”
Stefan Heuser, Senior Vice President & General Manager Business Unit Catalysts at Clariant, added, “We have successfully supported Petrowidada for more than a decade. It is close partnerships such as this that reveal valuable insights into our customers’ needs and challenges, and ultimately result in true breakthroughs in catalyst development like OxyMax PA 690.”
