Options for refinery decarbonisation
While there has been a focus on switching to low carbon hydrogen feeds, many options exist to decarbonise refineries, including energy efficiency, carbon capture and changing to bio-feedstocks.

Cartagena Refinery has entered the solid sulphur market, diversifying its petrochemical portfolio, according to a company statement on 21 May. The first shipment of 260 tonnes has already been dispatched to the domestic market. This new venture is enabled by a recently commissioned pelletising plant that converts liquid sulphur into solid pellets, with a production capacity of 1,000 t/d. The refinery is targeting Colombia’s fertilizer, chemical, and mining industries, and is also planning to export to international markets, including Brazil, Peru, and countries in Africa.
Axens says that it has strengthened its collaboration with Egyptian Refining Company (ERC) via a long-term agreement aimed at maximising asset value and supporting ERC’s evolving needs in product supply, digital transformation, and refinery performance optimisation. Under the agreement, Axens will use its integrated portfolio of technologies, equipment, catalysts, and services to support ERC’s operational, economic, and sustainability objectives.
Sulphur production continues to expand in the Middle East and East and South Asia both from new refineries and major sour gas projects.
Following an increase in its processing capacity, Duqm Refinery is now looking at further expansion projects at the $9 billion refinery project located, in the Special Economic Zone at Duqm (SEZAD) on Oman’s southeast coast. The refinery, which now has an expanded capacity of 255,000 bbl/d, is run by OQ8, a joint venture between Kuwait Petroleum International (KPI) and Oman’s OQ Group. Speaking to local media, CEO Abdulla Al Ajmi said that OQ8 has now begun front end engineering design on a reformer unit to upgrade naphtha into high-octane gasoline components such as reformate, a critical step in producing finished, specification-grade fuels. In addition to the proposed reformer unit, Duqm Refinery is also exploring opportunities to enhance value creation from its refining by-products, notably sulphur and coke.
The US Chemical Safety and Hazard Investigation Board (CSB) has released its final investigation report into the fatal release of hydrogen sulphide at the PEMEX Deer Park Refinery in Texas in October 2024.
Maire Group subsidiary KTKinetics Technology says that it has completed work on the Rijeka Refinery Upgrade Project in Croatia, having completed the engineering, procurement and construction activities. The scope of work included a new delayed coking unit to process heavy residue and eliminate the production of fuel oil while increasing refinery efficiency capacity, the revamping of the process units and the utility network and the implementation of the latest solutions for coke handling and storage and sea jetty construction and shipping loading facilities.
Repsol says that it is planning a 100MW green hydrogen plant to supply its Petronor refinery near Bilbao. From 2029, the plant will supply the refinery with 15,000 t/a of green hydrogen. Repsol says that the installation could prevent up to 167,000 tonnes of carbon dioxide emissions per year. The €292m ($346m) project has already secured €160m ($190m) in NextGenerationEU funds from the Spanish Recovery, Transformation, and Resilience Plan, after being recognised as a Project of Common European Interest by the European Commission.
Romanian oil and gas group OMV Petrom has commissioned a new sulphur recovery unit at its Petrobrazi refinery, near the southern city of Ploiesti. Development work on the new SRU began in 2023, and represents the second at the site, treating acid gas produced during the refining process. The euro 45 million investment is part of euro 2 billion of improvements that have been made over the past 20 years as part of the company’s strategy to modernise its refining capabilities, aiming to reduce environmental impact. Last year, the company said it would invest around euro 750 million to build several sustainable fuel plants at the refinery, which are expected to become operational in 2028.
Viva Energy has commissioned a new ultra-low sulphur gasoline (ULSG) plant at its Geelong refinery to meet Australia’s updated fuel standards, which came into effect on December 15. Under the standards, all gasoline grades must contain a maximum of 10 parts per million (ppm) sulphur, a so-called Euro-V standard. The ULSG plant was officially opened by the Minister for Climate Change and Energy, Chris Bowen MP, alongside Viva Energy Chairman Robert Hill and CEO Scott Wyatt.
