ICC - Process Overview Image: //cdn.intratec.us/images/icc/process-overview/044-D.jpg
ICC - Process Overview Text: <h6>Product</h6> <p><b>PTA</b>. PTA (Purified Terephthalic Acid) is a key raw material in the production of polyethylene terephthalate (PET), widely used in packaging, textiles, and plastic bottles. Its high purity ensures that it meets the quality demands of industries that require transparency and strength in their end products. PTA is produced via the oxidation of paraxylene in the presence of acetic acid. It is typically stored and transported as a white crystalline powder, which is easy to handle and distribute to manufacturers of PET and polyester fibers.</p> <h6>Raw Materials</h6> <p><b>Chemicals</b>. </p> <b>Paraxylene</b>. 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 pxylene separation.</p> <b>Acetic Acid</b>. Acetic acid (also known as ethanoic acid, hydrogen acetate) is a carboxylic acid found in dilute solutions in plant and animal systems. This chemical is widely used in organic processes, primarily in the production of polymers derived from vinyl acetate, used in paints and coatings, cellulose used to produce acetate fibers, and as solvent. While 2–12 wt% acetic acid solutions, usually called vinegar, have long been produced by ethanol fermentation, nowadays the commercial production of acetic acid is mainly based on methanol carbonylation and liquid-phase oxidation of n-butane.</p>
ICC - Process Schematic Image: //cdn.intratec.us/images/icc/process-schematics/044-D.jpg
ICC - Process Schematic Text: <p>The process under analysis can be divided into three main areas: (1) Oxidation; (2) Purification; and (3) Finishing.</p><p>Oxidation. P-xylene and the catalyst are mixed with the acetic acid solvent and fed to a CSTR. Air is also introduced to the reactor, from its bottom, to act as the oxidizing agent to turn p-xylene into Terephthalic Acid. The heat of reaction causes the evaporation of the water produced and some of the solvent and p-xylene. This gaseous mixture is vented from the reactor along with the reaction residual gas and then fed to a column producing a bottom stream of acetic acid and p-xylene that returns to the reactor and an overhead stream that is treated in a catalytic combustion unit before being discharged. From the bottom of the reactor comes out a slurry of Crude Terephthalic Acid that proceeds to purification steps downstream.</p><p>Purification. The CTA slurry is filtered and washed with p-xylene. The mother solution and the wash effluent are returned to the reactor, while the separated cake is solubilized in NMP, heated, and bubbled with nitrogen to remove remaining p-xylene, which is returned to the reactor while the solution proceeds to a crystallizer. In the crystallizer, the temperature is dropped, causing precipitation of the Terephthalic Acid, which forms a slurry to be filtered. In this second filtration, the cake is washed with NMP. The mother solution and the wash effluent are fed to a distillation column to recover the NMP while the cake receives fresh NMP and proceeds to a second crystallization. Again, the temperature is reduced, a terephthalic acid slurry is formed and it is sent to filtration. In this third filtration, the cake is washed with NMP and with methanol. The mother solution and the NMP wash are recycled as solvents for the step preceding the first filter, the methanol wash is recovered, and the cake goes to a dryer.</p><p>Finishing. The purified Terephthalic Acid crystals, coming out of the third filtration, are dried and sent to storage. The separated methanol leaving the dryer is recovered and recycled.</p>
ICC - Short Description: This analysis presents production cost of Purified Terephthalic Acid (PTA) production from p-xylene. The process examined in this report is similar to that one developed by GTC Technology. Differently from the conventional technology, this process does not involve a hydrogenation step for Terephthalic Acid purification after oxidation. The economic analysis assumes a plant located in the USA..
