Hindustan Petroleum Corp. Ltd. (HPCL) has let a contract to L&T Hydrocarbon Engineering Ltd. (LTHE) to provide engineering, procurement, construction, and commissioning (EPCC) for a new plant to be added as part of HPCL’s previously announced program to expand and modernize its 166,700-b/d Vishakhapatnam (Visakh) refinery in Andhra Pradesh on India’s southeastern coast (OGJ Online, Mar. 21, 2017).
As part of the contract, LTHE will deliver EPCC services for a new residue upgrading facility (RUF) under EPCC Package 3 of the Visakh refinery modernization project (VRMP), Larsen & Tourbo said.
To be equipped with technology licensed by Chevron Lummus Global, the 70,300-b/d plant—to be the first of its kind in India—will enable HPCL to convert the heaviest oils into high-quality Euro 6 diesel while simultaneously eliminating fuel oil production, as well as increasing feedstock and product flexibility, according to the service provider.
Awarded on a lump-sum turnkey basis, this latest contract follows previous contract awards to LTHE to deliver EPCC services for a crude distillation unit (CDU) and vacuum distillation unit (VDU) that will have a combined nameplate capacity of 180,700 b/d, as well as EPCC services on a 61,300-b/d full-conversion hydrocracker to be added as part of the VRMP (OGJ Online, Mar. 29, 2019; Mar. 21, 2018).
Since project approval in January 2016, HPCL has let multiple contracts for the brownfield VRMP, which proposes to expand refining capacity of the site to more than 300,000 b/d as well as boost production of low-sulfur fuels conforming to Euro 5 and Euro 6-quality standards (OGJ Online, Sept. 27, 2018; July 20, 2018; Jun. 11, 2018; Mar. 7, 2018; Jan. 5, 2018; Jan. 19, 2016).
The 209.28-billion VRMP remains on schedule for mechanical completion in July 2020, according to HPCL’s web site.
Project scope
According to India’s Ministry of Environment, Forest, and Climate Change, HPCL’s originally proposed 208 billion-rupee VRMP was to add the following units at the refinery:
- A 180,700-b/d CDU-VDU, which will replace one of Visakh’s three existing CDUs.
- A 66,300-b/d full-conversion, vacuum gas oil hydrocracker.
- A 5,860-b/d naphtha isomerization unit.
- A 62,250 solvent deasphalting unit.
- A 50,200-b/d slurry hydrocracker.
- A 96-tonne/day propylene recovery unit (PRU), which will replace an existing 216-tonne/day PRU.
- Two 113,000-tpy hydrogen generation units (226,000 tpy total).
- Two 360-tonne/day sulfur recovery units (720 tonnes/day total, including tail gas treatment).
- A 36,000-tpy fuel gas pressure-swing adsorption unit.
- A 300-tonne/hr nonhydroprocessing sour-water stripper.
- A 185-tonne/hr hydroprocessing sour-water stripper.
- Two 540-tonne/hr amine regeneration units (1,080 tonnes/hr total).
- A 112,000-tpy sulfur recovery LPG treating unit.
- A 1,000-cu m/hr integrated effluent treatment plant (EFP), which will replace all existing EFPs at the site.
According to the latest project information available from HPCL and general contractor Engineers India Ltd., major processing units at the refinery are scheduled for revamp as follows:
- A 30% capacity expansion of the naphtha hydrotreater in the refinery’s Motor Spirit (MS) block to 30,120 b/d.
- A 35% capacity expansion of the continuous catalytic reforming unit in the MS block to 20, 890 b/d.
- A 30% capacity expansion of the diesel hydrotreating unit to 57,430 b/d.
- An upgrade of the naphtha hydrotreater downstream of the refinery’s fluid catalytic cracker to enable output of BS V and BS VI-grade (equivalent to Euro 5 and Euro 6-quality) fuels.
