Jacobs Engineering contracted AH ARM/Gulf Consult to prepare an EIA for the Saudi Chevron Phillips Petrochemical Conversion Company. The new facility will produce nylon 6,6 from 90 wt. % Hexamethylenediamine [1,6-hexanediamine, H2N(CH2)6NH2] water solution (HMDA) and Adipic Acid powder (ADA) [Hexanedioic Acid, HOOC(CH2)4COOH] in Jubail Industrial City, KSA. The proposed facility also includes a nylon compounding unit in which the raw nylon polymer is mixed with various additives to produce the required characteristics for various products. The plant includes facilities for the fabrication of pipe, pharmaceutical products, complex caps and closures, automotive parts, electrical fittings and drip irrigation tubing. ARM was responsible for completion of the technical assessment of all environmental impacts to meet World Bank/IFC standards.
