The TPR^™ (Technip Parallel Reformer) is a proprietary gas-heated, convective steam reforming reactor designed to be integrated in parallel with a conventional fired Steam Methane Reformer (SMR) in a Hydrogen Generation Unit (HGU), enabling up to 30% additional hydrogen production without any incremental fuel firing. Rather than deriving its reaction heat from combustion, the TPR recovers high-grade thermal energy from the hot SMR effluent — typically at 850–950 °C — and uses it to drive the same endothermic steam reforming reactions inside its catalyst-filled tubes, effectively converting waste heat into productive reforming duty. The combined effluent from both the SMR and the TPR is then routed to a proprietary Dual Chamber Process Gas Boiler (PGB), followed by water-gas shift conversion and PSA purification, following the conventional HGU flowsheet. This configuration delivers a lower CO₂ footprint per unit of hydrogen produced, reduced fuel consumption, and significantly lower capital cost per incremental Nm³/h of H₂ compared to building additional fired reforming capacity. With 11 commercial references — predominantly in refinery hydrogen plants across Europe and India — and its landmark first grassroot installation at the HPCL Visakh refinery in India (2021, 262 KTPA total hydrogen capacity), the TPR has established itself as Technip Energies' flagship technology for energy-efficient, cost-effective hydrogen production optimization.
