Titre : Process and cost modeling of saturated branched - chain fatty acid isomer production Type de document : texte imprimé Auteurs : Helen L. Ngo, Auteur ; Winnie C. Yee, Auteur ; Andrew J. McAloon, Auteur Année de publication : 2012 Article en page(s) : pp. 12041–12045 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Modeling Acid Isomer Résumé : For decades, lubricants and hydraulic fluids were almost entirely based on petroleum. In recent years, the potential health risks of these materials as a result of their poor biodegradability have stimulated public awareness and concerns. It is therefore becoming increasingly important to implement environmentally friendly biobased fluids for the chemical industries. The development of new heterogeneous chemocatalytic processes for the conversion of vegetable oils and animal fats into high-value biobased industrial products can also have important positive impacts on the U.S. agriculture industry. Saturated branched-chain fatty acid isomers (sbc-FAs) such as isostearic acid, which are produced from renewable materials, are of interest because of their excellent lubricity and potentially good biodegradability. These unique features make them attractive in many important applications. Currently, sbc-FAs are produced as a byproduct of industrial dimer acid production, are synthesized in small quantities, and are costly to produce. In this paper, an efficient and effective isomerization process that produces predominantly the sbc-FA materials is presented as a case study to evaluate the potential of the technology to be implemented on the industrial scale. The case study was simulated using SuperPro Designer software to estimate the capital and process costs for producing sbc-FAs at an annual production of 4.5 × 106 kg (10 × 106 lb). The studies show that the process is cost-effective, with an estimated production cost of U.S. $2.53 kg–1 ($1.15 lb–1).
