摘要

Process simulation models can offer significant capabilities for operatingrnpersonnel to analyze and troubleshoot current performance and to develop optimumrnresponses in a proactive manner. This can increase agility in decision making, improvernreliability and lower operating cost. Historically, only engineers have had the knowledgernof how to utilize these process models. Limited engineering resources and lack of offshiftrnavailability can limit a model's effectiveness. To more fully realize these benefits,rnoperating personnel need an easy-to-use interface driven by robust and reliablernsimulation models. This paper discusses the best practices of using simulation modelsrnin operations, and demonstrates how new developments in modeling technologies canrnhelp.rnThe Valero Paulsboro Refinery has applied its crude unit simulation model forrnoperational troubleshooting, analysis and optimization. This paper outlines thernchallenges and opportunities of using this model. It also illustrates the use of AspenrnSimulation Workbook (ASW) to develop a Microsoft Excel based user-friendly interfacernto link high fidelity simulation models with the data historian tags, and to automate therncomplex workflow. In addition, it demonstrates how the Aspen HYSYS model wasrnupgraded to an advanced model using Aspen RefSYS to provide a robust model thatrnhas been used to evaluate over 10 different crude assays and track petroleumrnproperties (e.g. Sulfur, Conradson Carbon, API, etc) of the products. Aspen RefSYSrnsimplifies the use of pseudo components in crude assay characterization and improvesrnthe convergence of atmospheric and vacuum columns.
