Total is one of the largest international oil and gas companies in the world. Its Port Arthur refinery, with a capacity of 174,000 crude barrels per day, was upgraded to enable processing of heavier sour crude oils. The changes required new process units and modifications to existing units to allow the conversion of deep cuts of heavy products into lighter, more useful transport fuels (thus, “deep conversion”).
The modernization comprised six new process units: a Delayed Coker Unit consisting of four coke drums, a Coker Naphtha Hydrotreater, a Cracked Distillate Hydrotreater, Vacuum Distillation Unit, PSA and a Sulfur Block.
Also included were two new substations at 230 kV and 69 kV and all the utility and offsite additions and changes needed to support the new process.
