What you’ll learn

Aspen HYSYS – Petroleum Assays and Oil Characterization

  • Manipulate the Physical Property Environment
  • Add/Edit/Manage/Model Hypothetical Compounds
  • Use the UNIFAC Component Builder
  • Enter the minimum required data for an ASSAY
  • Oil Characterization
  • Input data for a Petroleum Assay
  • Display distribution plots, oil properties, curves, etc…
  • Install the oil into Aspen HYSYS Flowsheet


  • Chemical Engineering Basics
  • Basic Petrochemistry
  • Aspen HYSYS® – Basic Knowledge (Recommended)
  • Aspen HYSYS® (Version 7 at least)


This is a course on Plant Simulation that will show you how to set up hypothetical compounds, oil assays, blends, and petroleum characterization using the Oil Manager of Aspen HYSYS.

You will learn about:

  • Hypothetical Compounds (Hypos)
    • Estimation of hypo compound data
    • Models via Chemical Structure UNIFAC Component Builder
    • Basis conversion/cloning of existing components
  •  The input of Petroleum Assay and Crude Oils
    • Typical Bulk Properties (Molar Weight, Density, Viscosity)
    • Distillation curves such as TBP (Total Boiling Point)
    • ASTM (D86, D1160, D86-D1160, D2887)
    • Chromatography
    • Light End
  • Oil Characterization
    • Using the Petroleum Assay Manager or the Oil Manager
    • Importing Assays: Existing Database
    • Creating Assays: Manually / Model
    • Cutting: Pseudocomponent generation
    • The blending of crude oils
    • Installing oils into Aspen HYSYS flowsheets
  • Getting Results (Plots, Graphs, Tables)
    • Property and Composition Tables
    • Distribution Plot (Off Gas, Light Short Run, Naphtha, Kerosene, Light Diesel, Heavy Diesel, Gasoil, Residue)
    • Oil Properties
    • Proper
    • Boiling Point Curves
    • Viscosity, Density, Molecular Weight Curves

This is helpful for students, teachers, engineers, and researchers in the area of R&D, especially those in the Oil and Gas or Petroleum Refining industry.

This is a “workshop-based” course, there are about 25% theory and about 75% of work!

Who this course is for:

  • Chemical Engineers
  • Process Engineers
  • Petrochemical Engineers
  • Teachers instructing AspenTech software
  • Petroleum Engineers
