Industry 4.0 for Aging Refineries - reduced hydrogen waste in the Mediterranean's largest refinery by 400,000 kg/month


As a key component to hydrosulpherization and hydroconversion operations, Hydrogen is indespensible to the petroleum-refining process. With a greater demand for cleaner automotive diesel oil (ADO), it becomes even more necessary for production. In a brownfield refinery, the hydrogen distribution network may be extremely complex to manage resulting in sub-optimal process conditions, and thus, insufficient performance.


The refinery ecosystem is an interconnected web of different, complex processes, each with unique demands, and constantly changing input variables. Variance in hydrogen purity and fluctuating flow measures further complicates the ability to effectively identify the optimal distribution of hydrogen throughout the network.  

With console operators stationed at different production and consumption units, the refinery eco-system is missing an understanding of the big picture. Coupled with a lacking availability of online and lab analysis it is difficult to properly manage the hydrogen network and process conditions.

Material balance reconciliation is manually computed from process engineers' experience using an approximated flow composition. The dependency on human processes for measurement and calculation means using approximated values whic results in insufficient accuracy and performance. 

A lack of communication, control, and understanding of key components creates a disconnect in the refining ecosystem. To operate at an optimal level processes must operate in unison, forming a cohesive system rather than a group of distinct activities.


H2.Net is a smart, real-time hydrogen network management system fully integrated with field and production scheduling systems to optimize and run hydrogen flow distribution while offering full visibility to refining processes.

Measurement Compensation

  • Manage bi-directional flows while accounting for purity and consumption for more accurate, actionable data. Say goodbye to manual meter reading and approximated calculations.


  • Enabling Unit and Equipment monitoring for consumption and beheavior results in an improved ability for each system component to communicate with the rest of the network, ensuring optimal conditions for maximum performance.

User Guidelines

  • Synchronization between system components allows for improved productivity by getting your refinery to work for you. Decisional Support, Graphical Hints, Measure Validation and Interpolation help you ensure performance levels are met.

Ensure Performance

  • Linear combination is used to satisfy scheduling targets in terms of feedstock and catalytic conversion of hydroprocessing units to identify the optimal network configuration.

Enhance Interaction

  • Improved communication between system components enables transparency and efficiency, providing continuous monitoring and a friendly UX equipped with guidelines for operators and process engineers. helped one of the largest refineries in the Medditerranean reduce Hydrogen waste up to 400,000 kilograms per month.
