Course Description

This 5 day course is planned to provide participants with latest know how of the safe operation of the steam reforming unit. This course provides a deeper understanding of the operating and monitoring of steam reformers. The use of hydrogen for petrochemicals, fertilizers and as energy carrier in connection with renewable energy production will increase substantially in the future as even more stringent environmental legislation is enforced. Hydrogen will be required by fertilizers, refineries and specialty chemical manufacturers to meet the global need for cleaner products. The growing fuel cell market will be dependent on hydrogen as a primary fuel source. Hydrogen requirements vary widely. In spite of efforts to produce hydrogen by processes involving solar energy, wind energy, nuclear energy and biofuels, fossil fuels remain the most feasible feedstock in the near term, and for commercial scale production of pure hydrogen, steam reforming remains the most economic and efficient.
