The unit is part of the deep conversion project at the refinery, reported PDVSA in an official statement on its website.

The D-8406 NH3 stripper unit weighs 341 tons, has a diameter of 9 meters and rises 52 meters into the air. The unit is designed to process 1,881 gallons per minute of sour water and generate 1,802 gallons per minute of stripped water, 19,095 pounds per hour of hydrogen sulfide and permit the controlled burning of 9,450 pounds per hour of ammonia. The objective of the unit is to remove diluted hydrogen sulfide and ammonia from the currents of the sour water that come from the following units: Vacuum Distillation (VDU), Sequential Hydro-Processing (SHP), Residual Processing (RWU), Amine Regeneration (ARU), Sulfur Recovery and Tail Gas Treatment (SRU), Hydrogen Recovery (HRU) and Gas Recovery (GRU).
