Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 10 (Mars 2012) . - pp. 3923–3931 Titre : Building and application of delayed coking structure - oriented lumping model Type de document : texte imprimé Auteurs : Lida Tian, Auteur ; Benxian Shen, Auteur ; Jichang Liu, Auteur Année de publication : 2012 Article en page(s) : pp. 3923–3931 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Building  coking Résumé : A structure-oriented lumping (SOL) model to predict the product distribution of delayed coking was built. The effects of feedstock properties and operational conditions on product distribution were analyzed with the proposed model. It was known from model calculation results that for the feedstock residue of this paper, the liquid yield increased 2.5% on average with a temperature increase of 10 °C, that mainly was equal to a 0.15 increase H/C of feedstock; the liquid yield increased 3.5% on average with a recycle ratio decrease of 0.15, that was mainly equal to a 5% carbon residue decrease of feedstock; and liquid yield increased 0.6% on average with a pressure decrease of 0.03 MPa.
