WebApr 7, 2024 · Here is her presentation abstract: The primary method for blue hydrogen production is mainly from natural gas (methane), using steam methane reforming (SMR) and carbon capture for decarbonization. The hydrogen recovered from the SMR process is commonly used as a feedstock for oil refining, fertilizer, or chemical production. WebThe increased methane content can be processed in the secondary reformer if the process air inlet temperature is increased to 400 °C. The lower operating temperature reduces the …
WebThis chapter outlines the lining of secondary reformers. It describes the factors influencing overheating. For the production of ammonia, the function of the secondary reformer is to remove a few per cent of residual methane from the primary gas by combustion with air that also serves to add the required amount of nitrogen to form synthesis gas. WebThe secondary reformer is much more compact than the primary reformer. In the secondary reformer, combustion of the process gas hydrocarbon in oxygen causes a temperature …
