HPCL Rajasthan Refinery Ltd. (HRRL), a 74-26% joint venture of Hindustan Petroleum Corp. Ltd. (HPCL) and the state government of Rajasthan, has let a contract to Chevron Lummus Global LLC (CLG)—a partnership of Chevron USA Inc. and McDermott International Inc.—to provide process technology for a coking unit at the JV’s planned 181,000-b/d integrated refinery and petrochemical complex now under construction at Pachpadra Tehsil, Barmer District, Rajasthan (OGJ Online, Jan. 10, 2018).
As part of the contract, CLG will deliver licensing and extended basic engineering design of a 48,200-b/d delayed coking plant based on CLG’s proprietary delayed coking technology, the service provider said.
CLG disclosed neither a value of the contract nor a timeframe for its work on the project.
This latest contract follows HRRL’s previous award to McDermott for license and basic engineering design of two 420,000-tonne/year polypropylene units that will use Lummus’ proprietary Novolen process reactors and proprietary NHP catalyst to produce a full range of polypropylene products at the new refinery (OGJ Online, Jan. 3, 2019).
Integrated project overview
Once completed, the refinery—which will take about 4 years to build—will be equipped to produce Bharat Stage 6-grade fuels (equivalent to Euro 6-quality) from a feedstock of both locally produced and Saudi Arabian crudes to meet increased demand for petroleum products in Rajasthan as well as other northern Indian states.
During its first 8 years of operation, the refinery will be designed to process 1.5 million tpy of Rajasthan crude from nearby Mangla fields and 7.5 million tpy of imported Arab Mix crude—consisting of Arab Light and Arab Heavy grades—before switching to a full 9 million-tpy feedstock slate of Arab Mix beginning in its ninth year of operation, according to documents filed with India’s Ministry of Environment, Forest, and Climate Change (MOEFCC).
According to Engineers India Ltd.’s revised environmental impact assessment for the Barmer project filed with MOEFCC in July 2017, the complex will include the following nameplate processing capacities:
• Crude distillation, 181,000 b/d.
• Vacuum distillation, 96,400 b/d.
