This presentation will explain a Blue Hydrogen Process, with a comparison from the conventional hydrogen production process, including the benefits of this process, such as the reduction in the reformer capacities, flue gas volume, carbon dioxide content, lower steam generation, smaller PSA units, and much purer carbon dioxide product. Also, highlighting the benefits of Large-Scale Blue Hydrogen Plants such as proven demonstrated capability of using a single train steam methane reformer, lowering steam export and stack flue gas emissions, reducing plant footprint, and decreasing the steam methane reforming size.
