Eni settled on using inferred properties models as part of a control and optimization application for two refineries on reformer units. Using improved rigorous models in operations would help achieving a more accurate and reliable control for the reformers. One solution identified was applying an open-loop advisory systems area and closed loop control and optimization area. In the present low-gasoline market, reformers must improve hydrogen (H₂) supply and consumption. European refiners, often, operate reforms to balance gasoline or hydrogen production.
