Type of simulation used
 Equipment Static Modelling
Short description of the project Low steam/carbon ratio in hydrogen plant decreases energy consumption but also may lead to carbon deposit entailing a risk of catalyst damage. A week knowledge of the feed gas composition as well as measurement errors led to week knowledge of steam/carbon ratio in the refinery of ERE and made it difficult to find the optimal operating ratio. The problem was solved with data reconciliation software and a static model of the system was created. The model identifies each hour certain key values that help the refinery to improve its operation.

Soft Benefits The information model identifies each hour helps to improve the follow-up of the unit and to better focus the
maintenance of its instrumentation, while at the same time operating the unit at the optimal S/C ratio.
Public quantitative benefits .The project resulted in energy savings of 0.5 M€/ year
