Medium-Purity Terephthalic Acid Production
Terephthalic Acid Operating Costs & Plant Construction Costs
This report presents the economics of Medium-Purity Terephthalic Acid (MTA) production. The analysis is based on a plant located in the United States starting from p-xylene using a typical catalytic oxidation process. In this process, p-xylene is oxidized to terephthalic acid (TPA). Then, the TPA is crystallized and recovered from the liquor and MTA is obtained as the final product.
The report provides a comprehensive study of Terephthalic Acid production and related Terephthalic Acid production cost, covering three key aspects: a complete description of the Terephthalic Acid production process examined; an in-depth analysis of the related Terephthalic Acid plant capital cost (Capex); and an evaluation of the respective Terephthalic Acid plant operating costs (Opex).
The Terephthalic Acid production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Terephthalic Acid plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Terephthalic Acid plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

Product
Terephthalic Acid. Terephthalic Acid is the most important dicarboxylic acid. It is obtained by catalytic, liquid-phase air oxidation of p-xylene. Most of the terephthalic acid produced commercially is purified to then be consumed as precursor to saturated polyesters, primarily PET (polyethylene terephthalate) and, to a lesser extent, PBT (polybutylene terephthalate).
Raw Material
Paraxylene. p-Xylene, or paraxylene is the most important commercial isomer among the xylenes group. Almost all of its production is converted to Terephthalic Acid and dimethyl terephthalate. p-Xylene is primarily manufactured by naphtha catalytic reforming, followed by separation of the xylenes isomers, crystallization or absorption for p-Xylene separation.

Purified Terephthalic Acid from p-Xylene (BP Technology)
This assessment presents the economics of Purified Terephthalic Acid (PTA) production from p-xylene. The economic analysis is based in a plant located in the United States. The process examined in this report is similar to BP X Technology. In this process, p-xylene is oxidized to terephthalic acid, which is hydrogenated to obtain PTA. Drying and storage of crude terephthalic acid is not necessary.

Purified Terephthalic Acid from p-Xylene (Conventional Process)
This study presents the economics of Purified Terephthalic Acid (PTA) production using p-xylene as the process feedstock. The study approaches the construction of a plant in the United States employing a conventional catalytic oxidation process. In this process, p-xylene is oxidized to terephthalic acid (TPA). The TPA is subjected to separation and drying steps, and then sent to hydrogenation to obtain PTA as the final product.
