Aspen RefSYS Hydrocracker™

Easy-to-use and rigorous hydroprocessing (hydrocracking and hydrotreating) model

Aspen RefSYS Hydrocracker is used to simulate hydroprocessing units that consist of reactor beds and associated recycle gas quench streams. It is based on a rigorous, multiple-lump reaction system using over 150 components. Aspen RefSYS Hydrocracker is deeply and conveniently integrated into more complex flowsheets using standard Aspen HYSYS® models and work processes, bringing high fidelity hydroprocessing modeling to a broader audience with its friendly HYSYS-based interface. Aspen RefSYS Reformer is a core element of aspenONE™ Process Engineering for Refining and Marketing

Features

  • Unit Operation Structure: Aspen RefSYS Hydrocracker is an Aspen RefSYS unit operation that can drag and drop onto a flowsheet like any other Aspen HYSYS unit operation and quickly integrate with a larger flowsheet.
  • Rigorous Reactor: The core models are rigorous reactor beds with associated recycle gas quench streams. Reactor kinetics and exothermic temperature profiles are solved using rigorous AspenTech thermodynamics.
  • Multiple Configurations: Multiple reactors and beds can be configured with easy-to-use wizards. Options span one-stage and two-stage hydrocrackers. Aspen RefSYS Hydrocracker can also be configured to model simpler hydrotreating only options.
  • Major Variables: All major operational hydroprocessing variables are available, such as feed rate, feed composition, reactor temperatures, recycle rates, system pressure, and purge rates.
  • Calibration: Powerful data reconciliation options are made easily accessible with friendly Aspen HYSYS-style interfaces to provide new and revolutionary work processes for model calibration.

Benefits

  • Improved Operations: Provides accurate analysis of hydroprocessor operations to improve profit margins with better feed stock selection and optimized operating targets.
  • Capital Expansion Studies: Provides detailed information about hydroprocessor performance in debottlenecking studies.
  • LP Planning Model Support: Provides accurate data for the support of the hydroprocessor submodels in the refinery LP planning model (e.g., Aspen PIMS™) to improve refinery crude feedstock selection and plant-wide optimization.
