Terephthalic Acid Production from p-Xylene - Cost Analysis - TPA E14A

Book excerpt: This report presents a cost analysis of Purified Terephthalic Acid (PTA) production from p-xylene. The process examined is similar to that one developed by GTC 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 purification in order to obtain PTA as the final product. Differently from the conventional technology, this process does not involve a hydrogenation step for Terephthalic Acid purification. This report was developed based essentially on the following reference(s): Keywords: Para-xylene, Paraxylene, TPA, CTA, Catalytic Oxidation, Acetic Acid, PET, Polyethylene Terephthalate, GTC Technology
