Abstract:
The aim of this study was to identify the optimum solutions for additives dosage in Diesel Oil Hydrotreating
Unit. The additivation phase in HDS unit has it`s own importance due to the fact that facilitate production of commercial
Diesel fuel improving quality specifications for this product. The main performance criterions considered to establish the
reliable solution were: reduction of additives technological consumption through accurate dosage, achievement of quality
specifications for commercial Diesel oil, elimination of dead time due to bad control of additivation phase. The new
concept was verified through dynamic simulation in similar conditions with industrial proces using two consecrate
simulation programmes Hysys and Aspen Dynamics.
Keywords:
optimal control, ratio controller, dynamic simulation
