Surge Arresters

Overvoltage surge arresters (also called SPD – Surge Protection Device) are mechanisms that allow to protect electrical equipment from overvoltages by absorbing the generated current. They can also be inserted in an already existing system in order not to modify the operation of the system.

Modernización Refinería Talara

The “Modernización Refinería Talara” project involves the refurbishment and modernization of the Talara refinery located in Peru. The project seeks to achieve two key objectives: reducing sulfur content in diesel, gasoline, and LPG fuels to a maximum of 50 ppm and increasing the refinery’s crude processing capacity from 65,000 to 95,000 barrels per day (BPD), allowing for the processing of heavy crude and conversion of residual products into marketable ones.

Livorno ENI Refinery

The Eni refinery in Livorno, located in Tuscany, is a historic industrial site founded in 1939. Originally established as a traditional oil refinery for processing crude oil, the infrastructure is now at the center of one of the most important Italian energy transition projects, aimed at its complete conversion into a latest-generation biorefinery. Once the transformation is complete, the facility will no longer process fossil fuels, but will exclusively treat biogenic feedstocks, such as used cooking oils, waste animal fats, and agri-food industry residues, to transform them into hydrogenated biofuels. With this new industrial asset, the project pursues a twofold objective. On one hand, it aims to produce clean fuels by replacing oil with biological waste and used cooking oils; this reduces CO₂ emissions in transport and helps Eni reach the goal of net-zero emissions by 2050. On the other hand, the conversion serves to save the factory and jobs, transforming an old plant that was at risk of closure into a modern site, thereby guaranteeing employment for all workers in the Livorno area.

West Qurna 1

West Qurna 1, discovered in 1973, is a large onshore oil field located in southern Iraq, approximately 50 km northwest of Basra. Operated by PetroChina, the field is considered one of the world’s largest Oil & Gas assets, with estimated recoverable reserves of more than 20 billion barrels. The project involves the development and production of crude oil through wells, treatment facilities and gathering infrastructure, with the objective of sustaining and increasing Iraq’s oil production while enhancing the value of the country’s energy resources.
