Once completed, the project is expected to produce 1.2 million metric tonnes of paraxylene annually. It will also increase its benzene production capacity to 495,000 tonnes per year.
Illinois/USA – Honeywell has recently announced that IRPC will use a range of advanced process technologies from Honeywell UOP for a new aromatics complex in Thailand’s Rayong Province. IRPC is a publicly traded petroleum and petrochemical company, and a subsidiary of PTT Group. The Thailand-based firm operates the first fully integrated petrochemical complex in Southeast Asia.
As part of the project, Honeywell UOP will provide licensing, design, key equipment and state-of-the-art catalysts and adsorbents. When completed in 2022, the complex will produce 1.2 million metric tonnes of paraxylene per year that is used to make plastic resins, films and fibers. It will also increase its benzene production capacity from 114,000 to 495,000 tonnes per year. Benzene is a fuel additive and ingredient in plastics, lubricants, rubber, dyes and detergents.
The project will include a Honeywell UOP CCR Platforming unit, which converts naphtha into high-octane gasoline and aromatics, and an LD Parex unit, which recovers high-purity paraxylene from mixed xylenes and uses a new, more energy efficient light desorbent.
The complex also will include Honeywell UOP Sulfolane technology to extract aromatics from the feed; Isomar technology to convert xylene isomers into more valuable paraxylene; and Tatoray technology, which converts toluene and C9 aromatics into mixed xylenes and high-purity benzene, and that more than doubles the yield of paraxylene from the naphtha feedstock.
