Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Adipic Acid purification. In this process, a crude Adipic Acid stream generated by a two-stage oxidation process (similar to Invista technology) is purified into fiber-grade Adipic Acid. The crude stream passes through a series of purification steps that include centrifugation, crystallization and drying. A mixture of adipic, glutaric, and succinic acids is generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Hexanedioic Acid, DuPont, Ketone/Alcohol Oil, Air Oxidation, Nitric Acid Oxidation, Boric Acid
