In the modeled refinery, diesel has lower efficiency than gasoline because ~80% and ~ 10% of the diesel are produced from distillate hydrotreater and hydrocracker, respectively, the energy intensities of which are higher than the units in gasoline production pathways such as gasoline hydrotreater, naphtha hydrotreater
, reformer, etc.
Both light and heavy naphthas are treated in the naphtha hydrotreater
. The heavy naphtha is also used as makeup diluent for the upstream Froth Treatment process.
Bahwan Engineering is also working on the Ruwais Refinery Expansion in the UAE where its scope includes mechanical and piping installation work for the Saturated Gas Plant Unit, Saturated LPG Treating Unit, Saturated Heavy Naphtha Hydrotreater
Unit and Kerosene Hydrotreating Unit.
Naphtha (B-1) is treated in the naphtha hydrotreater
. At present, the LGO [TABULAR DATA FOR TABLE 1 OMITTED] (B-2) and HGO (B-3) are combined, and the combined gas oil (B4) is treated in the heavy gas oil hydrotreater.
The scope of the scheme involves building the Crude Distillation Unit MAB Unit 111, Atmospheric Residue Desulphurisation (ARDS) Unit MAB Units 112/212, Hydrocracker Unit (HCR) MAB Unit 114 & MAB Unit 214, Diesel Hydrotreating (DHT) Unit MAB Unit 116 & MAB Unit 216, Continuous Catalytic Reformer (CCR) MAB Unit 127, Naphtha Hydrotreater
(NHT) Unit (23500 BPSD) MAB Units 117, Underground Piping MAB Unit 179, Vacuum Rerun (VR) Unit MAB Unit 213 and DHT Flare MAB Unit 249.
The FCC reactor has been purchased and is in storage.The refinery expansion, in addition to increasing the crude throughput capacity to 75,000 bpd from 60,000 bpd, will increase the diesel hydtrotreater capacity to 36,000 bpd from 25,000 bpd and the naphtha hydrotreater
to 28,000 bpd from 22,000 bpd, the company said.Delek said it plans to access additional crude from the Cushing, Oklahoma, and Longview and Midland, Texas, areas.The product yield is expected to be increased approximately 10,100 bpd after the expansion.
Energy intelligence firm Genscape reported a CDU, VDU, catalytic reformer, naphtha hydrotreater
, heavy gas oil hydrotreater and coker were restarted at the refinery following planned work.
Project scope The scope of work is likely to include a naphtha hydrotreater
, reformer unit, olefins hydrogenation, BT extraction unit, paraxylene unit, isomerisation unit and transalkylation unit.
