Petrochemicals by Platinum Reforming
World’s Largest Aromatics Plant
The world’s largest aromatics petrochemical plant recently began production in Puerto Rico. Operated by Commonwealth Petrochemicals Inc., a subsidiary of Commonwealth Oil Refining Company, the plant receives raw naphtha feedstock both from the parent company’s refinery and by tanker from Venezuela. The naphtha is fed to a Unifining process unit where it is catalytically desulphurised, and thence to a Platforming unit where it is reformed over a platinum catalyst to produce a high yield of aromatics. These are separated in a Sulfolane unit and finally produced as high purity benzene, toluene, ortho-xylene and mixed xylenes. The total annual capacity of the plant is 172 million gallons of aromatics. Five of the plant’s major units were designed by Universal Oil Products Company.
