Milan, 10 August 2026 – Further to previous communications issued during the first half of 2026, MAIRE (MAIRE.MI) provides additional details regarding the Rich Gas Development (RGD) - Phase 3 project to be delivered by Tecnimont, part of the IE&CS business unit.

The project, which was awarded by ADNOC Gas – a subsidiary of Abu Dhabi National Oil Company – entails the expansion of the Ruwais Natural Gas Liquids (NGL) facility in Abu Dhabi (UAE) for a total value of USD 4.3 billion. Such contract was already included in the backlog as of the first half of 2026 communicated to the market.

The scope of work includes engineering, procurement and construction activities for the fifth NGL fractionation unit, which will separate the various hydrocarbon components, together with treatment and sweetening systems designed to remove impurities and ensure product quality. It also comprises the regeneration gas treatment unit, the propane refrigeration system, the ancillary systems and the storage facilities. Once completed in 2030, this plant will have an output capacity of 23,000 tonnes per day (t/d), or about 8 million tonnes per year.

NGLs primarily include ethane, propane, butane, isobutane, and pentane, which are separated from raw natural gas during processing and liquefied. They are used as feedstocks for plastics, heating fuels (propane), and gasoline blending. NGLs are crucial to a wide range of manufacturing industries, providing raw materials for products ranging from clothing to automotive parts.

This initiative represents the third phase of ADNOC’s Rich Gas Development program focusing on increasing the recovery of higher-value liquids from rich natural gas for export.
