Many processes throughout the petrochemical industry are based on the use of hydrogen produced by the reforming process, where a hydrocarbon-steam mixture is converted into a hydrogen-rich gas in the presence of a catalyst at elevated temperatures and pressures. The recent increases in the demand for hydrogen as a synthesis gas in the refining industry, along with the need to meet clean fuel requirements, have increased the demand for hydrogen production. Selas Linde North America (SLNA) has executed over 250 hydrogen reformer contracts worldwide and we were the first independent heater supplier to design, construct, and offer process guarantees for reforming furnaces in the United States.
Our reformer designs are in operation throughout the world on virtually all types of feed stocks, from natural gas through naphtha, and offer conversion to:
- Mixtures of hydrogen and carbon monoxide synthesis gas for methanol or oxo-chemical production
- Mixtures of hydrogen and nitrogen for ammonia production
- Production of natural gas substitutes
The SLNA reformer process design is performed with a proprietary incremental kinetic model that was developed in-house, and refined with data from over sixty years of operating experience. This model predicts the reforming process for a variety of feed stocks, and reformer configurations. Our top fired design combines both process and physical arrangement benefits to minimize the total cost of ownership.
Optimization of the reformer with the waste heat recovery section can be tailored to suit multiple design cases for varying feed stock, fuels, and steam requirements. Waste heat recovery from flue gas and process gas is an important aspect of Linde Engineering's overall reformer design. Our technology encompasses a complete range of heat recovery concepts and equipment choices. This may take the form of combustion air preheat systems, steam generation, carbon dioxide recovery and gas turbine integration. In each case, we will select the type of heat recovery system that best suits the needs of our customers.
