FIRE WATER ADEQUACY STUDY NETWORK AND ASSOCIATED FACILITIES AS PER OISD STANDARD-116 FOR IOCL,BONGAIGAON REFINERY

FIRE WATER ADEQUACY STUDY NETWORK

Indian Oil Corporation Limited has awarded iFluids Engineering to carry "FIRE WATER ADEQUACY STUDY NETWORK AND ASSOCIATED FACILITIES AS PER OISD-STD-116 FOR BONGAIGAON REFINERY"

Bongaigaon Refinery is a petroleum refinery in Assam, India. It was commissioned on 20 February 1974 by the government of India.Refinery capacity was increased in 1995 to 2.35 million tonnes per year (51400 barrels per day of stream through expansion.

The study is performed for checking the adequacy of the existing fire, water network and identify their limitations while considering different combinations of the fire scenarios (as per OISD-STD-1116 ).

Existing facilities to be covered under this study are:

  • Crude Distillation Unit (CDU-I & II)
  • Delayed Coker Unit (DCU-I & II)
  • CRU MSQ Block (NHT, CRU, Coker Naphtha Splitter, SR Naphtha splitter, Light Naphtha ISOM unit)
  • DHDT Block (DHDT, HGU, SRU, SWSU, ARU, Nitrogen plant, SRR)
  • Captive Power Plant (Boilers (5 Nos.),STG (3 nos.), GTG (1 no.),HRSG (1 No.)
  • Hydrocarbon Storage Tanks (122 nos.) and 3 nos. Of LPG Horton spheres, 4 bays of LPG TT loading. Truck, LPG Bullet and Rail Wagon loading facilities/gantries.
  • Utilities & Off-sites, WWTP (ETP and TTP), LPG Bottling plant, Hydrogen storage (CRU Unit and DHDT block), Compressed air system, Instrument air system, firewater network
  • Flare Systems (Refinery, CRU MSQ units, DHDT Block), DM PLANT,CPU unit, Fuel gas and fuel oil network. KTU, Coke calculations Unit, All Electrical Substations of units, Bongaigaon refinery, CCU, Store & Warehouse.(Storage, Loading/unloading facility of chemicals etc.)

Upcoming new facilities to be cover under the study are:
