Crude Oil Column SIM 4300

Model Description

The TSC SIM 4300 Crude Column Simulation is a multi page model showing a multi-stage distillation column taking a multicomponent hydrocarbon feed and splitting it into six fractions.

The column is used to split the feed into 6 major product cuts. These are off gas, naptha, kerosene, diesel, gas oil and residue. Each of the product side streams have a collection vessel before each of the products are cooled using a heat recovery system to heat the feed stream.

The feed is then passed through a furnace before entering the column. This drives a gas flow up through the column.

Each fraction offtake contains flow, level and temperature control, gas return and pumped product offtake.

The column can be fully shutdown and restarted and included with the model is a fully shutdown and Nitrogen purged column to allow easy startup training.

There is a fully functional ESD (emergency shutdown) system included with Inhibits, startup overrides and executive action. The display is presented in a standard cause and effect matrix including and/or logic action.

At various points on the column there are standard analysis techniques for product quality including Dew Point, Cloud Point and TBP90 (90% boiling point). For more advanced use the trainer can grant access to a full mole fraction analysis of certain streams.

For advanced use the model contains a tray to tray analysis of flow, pressure temperature and composition allowing a trainee to see exactly how a change in conditions effects a running crude column.

Learning Areas

  • Introduction to a standard crude column as used in industry including features for advanced realism including heat recovery and multiple fraction offtakes.
  • Allows various startup techniques to be tested and then process optimisation using industry standard analysis techniques.
  • For advanced use tray to tray properties can lead to enhanced understanding of what is happening within a crude column.
  • Builds on previous modelled unit operations such as binary column, condensation and heat exchange.
