Flagship Engineering Cases

Leveraging strong technology and supply chain resources, PIONTTERN deeply participates in catalyst supply for major refining, gas purification, new-energy chemical, and environmental upgrade projects at home and abroad. The following are flagship delivered cases covering mainstream demand scenarios in the Middle East market.

01Case Study

Ultra-Deep Diesel Hydrotreating Catalyst Supply for a Major Refinery

Diesel sulfur stabilized below 10ppm, fully meeting Middle East clean fuel standards; catalyst run length greatly extended with 35% lower overall operating costs. Successfully replaced the full imported hydrogenation range and established a long-term annual supply agreement.
