| Abstract: | ObjectiveIn order to reduce the cost and CO2 emission of 40×103 m3/h hydrogen production unit of a petrochemical company, natural gas instead of naphtha is planned to be used as the raw material for hydrogen production. MethodsThe raw materials, existing processes and catalysts were analyzed, and the process parameters under different raw material conditions were optimized. ResultsNatural gas is successfully used to replace naphtha and refinery gas as the raw material for hydrogen production and the risk of furnace tube over temperature after raw material transformation is eliminated. ConclusionsComparing the working conditions of natural gas and naphtha in the unit, when the processing load and process parameters are under the similar conditions, the energy consumption, hydrogen production cost and carbon emission of using natural gas as raw material are lower than naphtha. |
