Primary reformer
Webutilized a primary or tubular reformer with a low outlet temperature and high methane leakage to reduce the size and cost of the reformer. Excess air was added to the second-ary reformer to reduce the methane content of the primary reformer exit stream to 1–2%. Excess nitrogen and other impurities were removed downstream of the methanator. WebSteam reforming of hydrocarbon feedstock is carried out in tlie priiiiiiry and secondary reformers. [Pg.260] Figure 8.21 shows the scheme for producing ammonia. First, the natural gas is desulfurized and then steam-reformed in the primary reformer into a mixture of unreacted methane (10-13 %), CO, CO2, and FI2 that is then combined with air ...

WebApr 7, 2024 · 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.
WebIn this project, the heat exchange system for the reforming section of an ammonia plant was optimized. The system consists of a single shell and tube process/process exchanger followed by a secondary cooling water exchanger. The primary exchanger heats the main feed before it enters the primary reformer, from 231.1 °C to 600 °C. onedrive redirected foldersonedrive redirectionAmmonia production has become one of the most important industries in the world.
