Course Content
IMPACT OF CRUDE OIL QUALITY ON PRODUCTS
-
Duration : 0.5 Day
Tuning of the volatility of petroleum fractions in view of their end-use: constraints and flexibility of cut points; principal problems related to quality.
Crude oils: properties (TBP analysis), product yields, related margins.
Main schemes for crude oil fractionation.
OPERATING CONDITIONS OF AN ATMOSPHERIC & VACUUM DISTILLATION UNITS
-
Duration : 2 Days
Material balance: cut points, product characteristics, separation quality, fractionation capability.
Top condensation and pressure in the column - Partial pressures.
Feed vaporization: inlet temperature, overflash.
Product side stripping.

PROCESS CONTROL, OPERATION & TROUBLESHOOTING OF MULTI-DRAW-OFF COLUMNS
-
Duration : 1 Day
Different control systems in atmospheric and vacuum distillation columns, using flowrate, level or temperature control.
Cut point control: modification of flowrate of a cut and consequences on the column.
Impact of the preflash on the operation of the furnace and the atmospheric column.
Separation control: tuning of the separation selectivity, consequences on the column and on the heat recovery system.
Influence of pressure and pressure control.
Case studies on overall control setup of these two distillation columns and disturbances.
Maximizing the performances of the unit under constraints or limit conditions.
Start-up - Shutdown - Troubleshooting.
DISTURBANCES & TROUBLESHOOTING
-
Duration : 0.5 Day
Case studies (in groups) related to disturbances and incidents; detection, consequences and corrective actions:
Stripping shutdown.
Failure of one pumparound pump, of the furnace.
Loss of part of the feed, etc.
Learning Objectives
Attendees will be able to implement the following skills:
