assets, is helping to create a circular econ- omy. The Jamnagar refinery has become the first in India to receive the prestigious ISCC PLUS certificate for producing circu- lar polymers through chemical recycling to reduce plastic waste. This initiative aims to reduce plastic waste, marking a significant step towards a greener future. To meet the sustainability target, the first consignment of circular polypropylene (CircuRepol ® ) was launched on 28 December 2023 from the RIL Jamnagar refinery. The circular polymer is being produced in exist- ing refinery units through chemical recycling of waste plastics using in-house waste plas- tic conversion technology.
Reliance Industries Limited (RIL) has dem- onstrated its commitment to sustainability by producing International Sustainability & Carbon Certification (ISCC) PLUS-certified circular polymer from waste plastics at its Jamnagar refinery. RIL’s technology for converting waste plastics to pyrolysis oil, along with innovative methods for pro- ducing circular polymer utilising existing

ing-based hydrogen generation units at its Mathura Refinery (MR). The unit was facing operational bottlenecks and reli- ability issues. The capacity of the unit was restricted due to tube skin temper- atures (TSTs) crossing the design limit above 70% plant load. Also, due to non- uniform firing, the furnace operation was imbalanced. Further, there were incidents of flame impingement on the tube, which resulted in reduced life and poor reliability of the catalyst tubes. To ensure tube reliability and opera- tional safety, a TST measurement is car- ried out. Unlike other furnaces, the TST measurement of the reformer tube is done manually using non-contact type infrared pyrometers due to the severe operating environment for the skin thermocouples of function. When using IR pyrometers for indirect temperature measurement, fac- tors such as emissivity, sight path effects, and reflected radiation can contribute to errors in temperature measurement. IR pyrometers capture all the radiation falling on their lens, including radiation emitted by the tube, radiation reflected by the tube surface, radiation reflected by the refractory walls, radiation due to the flames, and they display everything as the tube temperature. This means that the actual tube temper- ature would be 900°C, but the pyrometer

Background and Problem Statement Hydrogen, also termed the ‘Champagne Fuel for the energy transition’, is one of the most important and costly utilities in refineries and petrochemicals. It is uti- lised for processes such as hydrocracking, hydrodesulphurisation, and hydrotreating of petroleum intermediates. Most refiners employ steam methane reforming (SMR)
ane reforming is a highly energy-intensive process. For this, the reformer furnace is operated in the 900-1,000°C range. To endure such severe operation condi- tions, the tube metallurgy is made of spe- cial alloys with excellent creep strength, fatigue strength, oxidation resistance, and structural stability. IOCL operates steam methane reform-
for hydrogen production, with the reformer furnace being the central component of the process. A typical steam methane reformer is a fired furnace with rows of tubes containing catalyst through which feed is passed. The feed is a mixture of steam and methane, which converts to hydrogen in the pres- ence of a catalyst and heat. Steam meth-
