Matheson Tri-Gas, Inc. will construct a hydrogen plant in Assam, India after winning an award for the supply of hydrogen and co-product steam from Numaligarh Refinery Limited (NRL), a public sector affiliate of the Government of India.
The deal will also see Nippon Sanso Holdings Corporation (NSHD)-owned Matheson supplying 285 tonnes per day of hydrogen to NRL’s refinery units at Numaligarh.
Larsen & Toubro Limited, India (L&T) will handle engineering and construction of the plant, while reforming technology will be licensed from Denmark-based Topsoe A/S.
The agreement will support the Numaligarh Refinery Expansion Project (NREP), the Indian government’s Northeast development initiative that includes the Paradip Numaligarh Crude Pipeline (PNCP) project, Crude Oil Import Terminal (COIT) at Paradip, India-Bangladesh Friendship Pipeline (IBFP), Numaligarh-Siliguri interstate products pipeline and 2G Ethanol Project.
Developed by Matheson’s Global HYCO business unit in collaboration with its partners, the Assam plant aims to harness a wide range of feedstock and fuel, in addition to the ‘highest resource utilisation efficiency’ in a drive to support Matheson/NSHD’s Carbon Index considerations.
