Prometheus is an independent consulting company that has been serving the oil refining industry for over 35 years. It provides products and services for refinery management that improve profitability, operations, and marketing decisions. From its main offices in Genoa, Italy, Prometheus specialises in Industrial Consulting for the oil process sector: oil refineries surveys, feasibility studies for saving energy, plant capacity, and product quality improvement, process design and technical assistance to refinery operations. The Software Sector offers its proven Decision Support System (DSS) for technical-economic optimisation and scheduling of oil and petrochemical industry logistics, processing, marketing, and transportation. As an independent company with extended experience in the private oil sector, Prometheus refinery surveys are oriented towards finding operating conditions and minor de-bottlenecking investments that can achieve substantial profitability improvements and maximise the use of existing facilities. The founder's direct experience in obtaining significant advantages through optimisation software tools led to the development of the DSS software. The DSS couples a friendly modern computer interface with sophisticated refinery models simulating the real process, logistics and marketing conditions to support oil refinery managers' daily decisions.
