- Steam Methane Reforming

From

0

Steam reforming of hydrocarbons is conventionally used for feedstock production for methanol synthesis, hydrogen production, ammonia synthesis and Fisher-Tropsch synthesis. Syn-Gas or Hydrogen can be produced using the Steam Methane Reforming process.

In the case of Syn-Gas production (CO + H2) for the ultimate production of liquid fuels using the Fisher-Tropsch synthesis, natural gas will be reformed in the presence of steam at a temperature of 750˚C to 800˚C. Steam reforming converts methane and other hydrocarbons in natural gas, into hydrogen and carbon monoxide by reaction with steam over a nickel based catalyst.

In the case of hydrogen production, the methane reforming step is followed by the Water Gas Shift (WGS) reaction. During that process the carbon monoxide part of the syn-gas produced is reacted with steam over a catalyst to convert CO into carbon dioxide (CO2) and hydrogen. The WGS reaction is first produced at a temperature of 350˚C which is called High Temperature Shift (HTS). The reaction is further completed at a lower temperature 190˚C to 210˚C Low Temperature Shift (LTS).

AirScience produces small to medium size SMR systems for the GTL industry in the range of 50,000 Nm3/h to 200,000 Nm3/h of syn-gas. We also produce small SMR system producing hydrogen to stationary fuel-cell power plants with a capacity of 0.5 to 2 MWe.
