EHY2102: Aspen HYSYS Petroleum Refining

Here is your complete guide to , focusing on process modeling and unit operations. 🎯 Course Overview & Objectives

  • Build a steady‑state flowsheet of the crude preheat train, atmospheric and vacuum columns, and associated pumps/heat exchangers.
  • Characterize feed with detailed assay and lump heavier components for accurate bottom property predictions.
  • Run sensitivity studies varying reflux ratio, column pressure, and heat exchanger duties to identify limits.
  • Model heat integration opportunities (e.g., adding a pinch‑driven exchanger) to recover heat from product streams.
  • Evaluate column tray efficiency and reboiler capacity; simulate staged feed preheating to shift load. Outcome: Identify an operational window (slightly higher vacuum, optimized reflux, improved preheat) that increases throughput by a modest percent while maintaining product specs—saving capital expenditure.
  • Compare simulated temperatures, flows, and product qualities; tweak models (lumping, kinetics, tray efficiencies) to match measured performance.

Debottlenecking Scenarios:

Participants use Column Analysis tools to identify limits on throughput, such as tray flooding or heat exchanger capacity, and investigate design changes like preheat train modifications. ehy2102 aspen hysys petroleum refiningunit o

  • 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.
