Terephthalic Acid Production from p-Xylene - Cost Analysis - TPA E13A

Book excerpt: This report presents a cost analysis of Purified Terephthalic Acid (PTA) production from p-xylene. The process examined is similar to BP X Technology. In this process, p-xylene is oxidized to Terephthalic Acid. The Terephthalic Acid from reaction is separated as a Crude Terephthalic Acid (CTA) intermediate. The CTA is subjected to hydrogenation and PTA is obtained as the final product. The drying and storage of the CTA intermediate is not necessary in this process. This report was developed based essentially on the following reference(s): (1) EP Patent 1054855, issued to BP Amoco in 2000 (2) US Patent 20150166452, issued to BP in 2015 Keywords: Para-xylene, Paraxylene, TPA, CTA, Hydrogenation, Amoco, Catalytic Oxidation, Acetic Acid, BP, X Technology, PET, Polyethylene Terephthalate
