This report presents a cost analysis of Adipic Acid production from benzene using a two-stage oxidation process. The process examined is similar to Invista process. The Adipic Acid plant is integrated upstream with a plant for cyclohexane production from benzene and a plant for nitric acid production. A mixture of Adipic, glutaric, and succinic acids is generated as by-product. This report was developed based essentially on the following reference(s): US Patent 20040054235, issued to DuPont in 2004 (assigned to Invista in 2004) Keywords: Hexanedioic Acid, Boric Acid, Ketone/Alcohol Oil, KA Oil, Cyclohexanone, Cyclohexanol
This report presents a cost analysis of Benzene production from light oil using a hydrodealkylation process. The process examined is similar to CB&I Lummus Litol process. In this process, the light oil feedstock is a by-product from the cooking of coal. This report was developed based essentially on the following reference(s): (1) "DETOL®, LITOL®, and PYROTOL® Hydrodealkylation", Tech Sheet, CB&I Lummus Technology (2) "Benzene", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Coke Oven Light Oil, COLO, Aromatics, BTX, Dealkylation, Houdry Division of Air Products, Bethlehem Steel
This report presents a cost analysis of Adipic Acid production from benzene. The process examined is similar to Asahi Kasei process. Benzene is partially hydrogenated to cyclohexene intermediate. Cyclohexene is then hydrated to produce cyclohexanol, which is further converted to Adipic Acid. Cyclohexane is generated as by-product. This report was developed based essentially on the following reference(s): US Patent 9056309, issued to Asahi Kasei in 2015 Keywords: Hexanedioic Acid, Ketone/Alcohol Oil, Alkylation, Oxidation, Cumene, Cumene Hydroperoxide, CHP
This report presents a cost analysis of Adipic Acid production from benzene and propylene. The process examined is a typical hydrogenation process. In this process, the Adipic Acid plant is integrated upstream with a plant for phenol production from benzene and propylene, and a plant for nitric acid production. Acetone is generated as by-product. This report was developed based essentially on the following reference(s): (1) "Phenol", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) "Cyclohexanol and Cyclohexanone", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Hexanedioic Acid, Ketone/Alcohol Oil, Alkylation, Oxidation, Cumene, Cumene Hydroperoxide, CHP, KA Oil, Cyclohexanone, Cyclohexanol
This report presents a cost analysis of Adipic Acid production from cyclohexane. The process examined is a two-stage oxidation process, similar to the Invista technology. In this process, cyclohexane is initially oxidized with air to produce KA oil (mixture of cyclohexanone and cyclohexanol). Subsequently, the KA oil is oxidized with nitric acid to produce Adipic Acid. A mixture of adipic, glutaric, and succinic acids is generated as by-product.

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.
