IOC�s Haldia Refinery-I: Expansion on pipeline for  Rs. 3215 crore

Indian Oil Corporation Ltd ( IOCL) is soon expecting clearance for its proposed  capacity expansion  from 7.5 MMTPA to 8.0 MMTPA at Haldia refinery in West Bengal at a cost of Rs. 3215 crore.
8The refinery now has two Crude Distillation Units (CDU) with the processing level of 7.5 MMTPA.
8Expansion is done by revamping the existing Crude Distillation Unit( CDU-I) from 3.3 MMTPA  to 3.8 MMTPA and  Vaccum Distillation Column (VDU-I) from 1.5 MMTPA to 1.7 MMTPA.
8To produce substantial quantity of Furnace Oil, a distillate yield improvement project is proposed, wherein units such as the Delayed Coker Unit (1.7 MMTPA), the Coker Gas Oil Hydrotreater Unit (1.4 MMTPA) and the Coker LPG treating Unit (70 TMTPA) are to be involved.
8In addition to that, refinery proposes to install a Feed Preparation Unit (FPU) for CDWU. The estimated capacity of the proposed UCO Vacuum Fractionation Unit (Feed Preparation Unit, FPU) shall be 650  TMTPA.

IOCL's Haldia Refinery-III: Distillate Yield Improvement Project

Haldia Refinery processes about 72% High Sulphur (HS) crude that is needed to produce LOBS. The processing of HS crude results in higher black oil generation.
8In absence of any processing facility to upgrade black oil, it is converted to low value products like High Sulphur Furnace Oil (HSFO) and Bitumen, thereby resulting in lower distillate yield.
8A Delayed Cocking Unit ( DCU) will be adopted for the Haldia Refinery which would enable black oil upgradation, beside processing increased quantity of High Sulphur crude as well as heavy crude.
8Here is a list of projects:
Delayed Coking Unit (DCU)                                1.7 MMTPA

Coker Gas Oil Hydrotreater Unit(CGO HDTU)    1.4 MMTPA

Coker LPG MEROX Unit                                     70 TMTPA

Sulphur Recovery Unit (SRU)                              80 TPD

Amine Treating Unit (ATU)                                  260 TPH

Sour Water Stripper (SWS)                                 65 TPH
8Hence, this project will bring higher profitability due to improvement in yield of valuable distillate products and eliminate HSFO output due to its declining demand, considering stricter environmental norms and future projection of natural gas availability in the country.

IOCL's Haldia Refinery-IV: Striving for API Gr-III LOBS Production

Haldia Refinery typically produces a total of around 230-240 TMTPA of LOBS, of which approximately

50-55% is of API Gr-II variety and there is no facility for API Gr-III LOBS production in refinery.
8The yield of solvent extraction units is also 50%,vaccum distillate requirement is high, thus lowering refinery distillate yield.
8Currently, refinery has commenced production of API Gr-II LOBS production through existing CDWU by processing admixture of bulk UCO and requisite amount of raffinate in order to meet minimum feed �S� and kinematic viscosity of final Lube products.
8Though it was instrumental in reduction of black oil pool volume, certain drawbacks were there.
8To extract complete lube potential from UCO, bulk UCO needs to be vacuum-fractioned into waxy heart-cuts for onward processing in CDW to meet final LOBS products� specs.
8Processing of neat UCO in CDW is not feasible as function of Hydrotreater reactor catalyst will be lost due to Sulfur leaching from active  metal sulfides.
 Hence, CDW shall need minor admixing of raffinate in the heart-cut streams.
8With the implementation of proposed facility, it is envisaged that Haldia Refinery shall be able to produce 100% Gr-III LOBS (of 70N/150N/500N grades).

IOCL's Haldia Refinery-V: Requirements and Source


No additional power generation facility is envisaged under the proposed projects. Instead, Haldia Refinery has initiated proposal for importing 40 MVA power from state grid (WBSEB) for usage in the refinery in post-project scenario.
8The existing and the proposed scenarios, pertaining to the power requirement are as under:
Existing                           60 MW

FPU                                 0.74 MW

DYIP                                29 MW

CDU-I/ VDU-I Revamp    0.6 MW

TOTAL                             90.34
8Total of 635 m3/hr. (550 m3/hr. for DYIP and  85 m3/hr. for FPU & capacity expansion), which will be met from the existing water supply system of the refinery.
