refers to a professional training course titled "Aspen HYSYS Petroleum Refining:
Build Complex Refinery Models: Create multi-unit flowsheets including distillation columns and advanced reactors.
Before building the flowsheets, you must characterize your feed.
1. Reactor Configuration (Hydrotreating)
- Adiabatic Reactors: The unit typically features one or more adiabatic fixed-bed reactors.
- Catalyst Specification: Allows for the definition of specific catalyst properties (surface area, pore volume, metal loading) relevant to VGO desulfurization and denitrogenation.
- Quench Zones: Capability to model inter-bed quench streams to control temperature rise (exothermic reaction) between catalyst beds.
Optimize Operations: Use the Aspen HYSYS Optimizer and Case Study tools to find the best operating points and debottleneck processes.
