The main unit of the complex is the 7500 Tpsd Vacuum
Residue Hydrocracker consisting of two-reactors with
interstage separator. This configuration is designed to
provide a conversion rate of 70% with the design
crudes. The unit includes an atmospheric and vacuum
distillation section, a recycle gas compression and
purification section with membrane unit, a swing
adsorption unit and a unit for catalyst handling.
In addition to the main hydrocracking unit the complex
includes a hydrogen production unit, a MDEA Project phased execution
