Byproduct hydrogen network design using pressure swing adsorption and recycling unit for the petrochemical complex / Changhyun Jeong in Industrial & engineering chemistry research, Vol. 50 N° 6 (Mars 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 6 (Mars 2011) . - pp. 3304-3311 Titre : Byproduct hydrogen network design using pressure swing adsorption and recycling unit for the petrochemical complex Type de document : texte imprimé Auteurs : Changhyun Jeong, Auteur ; Chonghun Han, Auteur Année de publication : 2011 Article en page(s) : pp. 3304-3311 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Petrochemical  industry  Recycling  Pressure  swing  adsorption  Design Résumé : Hydrogen, which has gained attention as the next-generation renewable energy source among byproducts, is a raw material that is commonly produced and consumed in all petrochemical complexes. It is also a primary energy source in energy systems that can considerably reduce air pollution and greenhouse gas emission. Therefore, an explosive demand for hydrogen is expected in the future. A considerable amount of hydrogen is produced as byproducts in industrial complexes such as petrochemical plants and oil refineries within a petrochemical complex; however, this hydrogen is mostly used as fuel internally. If a considerable amount of hydrogen that is used as fuel can be recycled as raw material for an energy source or for other processes, hydrogen can be of a considerably higher value than it is at present. In this research, we have designed a byproduct hydrogen network between a source and a sink within a petrochemical complex. We determined the minimum fresh hydrogen and recovery hydrogen that are needed for forming a material exchange network through hydrogen pinch analysis and finally designed the hydrogen recycling network between the source plant and the sink plant by building a network optimization problem in which the cost and constraints needed to build the network were considered.

Optimal gas-to-liquid product selection from natural gas under uncertain price scenarios / Chul-Jin Lee in Industrial & engineering chemistry research, Vol. 48 N°2 (Janvier 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°2 (Janvier 2009) . - p. 794–800 Titre : Optimal gas-to-liquid product selection from natural gas under uncertain price scenarios Type de document : texte imprimé Auteurs : Chul-Jin Lee, Auteur ; Youngsub Lim, Auteur ; Ho Soo Kim, Auteur ; Chonghun Han, Auteur Année de publication : 2009 Article en page(s) : p. 794–800 Note générale : chemical engineering Langues : Anglais (eng) Mots-clés : Optimal  Gas Résumé : Gas-to-liquid (GTL) products have come into the spotlight for alternative energy carriers as an environmentally benign and highly profitable alternative to petroleum resources. There have been various studies conducted to explore the economic and environmental benefits of individual GTL products, but few researchers have performed a comparative economic assessment, determining which product would make the greatest profit among various GTL products. Furthermore, considering the inherent characteristics of process industries, profits from one product are deeply dependent on the price of its raw material. Thus, it is important to choose an optimal GTL product covering those price variations. In this study, we performed economic analyses for three GTL products used for transportation fuel through process modeling and investigated the profitability according to variations in feedstock cost and product price.
