  • Heat Exchanger Reformer Industrial Efficiency …

    The reformer exchanger uses high temperature process heat exiting the secondary reformer (or exiting an auto-thermal reformer) to produce syngas by reforming an additional flow of natural gas and steam. In this way additional reforming capacity is realized by utilizing heat available in the existing unit that was previously used for steam generation.
