The 8th SulGas® Mumbai sulphur recovery and gas treating conference and exhibition, organised by Three Ten Initiative Technologies LLP, took place on 5 and 6 February 2026. We report on some of the key topics on the agenda.

Efficient sulphur recovery is essential for modern refineries to meet stringent environmental regulations and support sustainability goals. Fluor examines the key design considerations, smart design strategies and flexible sulphur block configurations that are essential in achieving an overall optimised design. Together, these strategies enhance efficiency, reduce emissions, improve reliability, and provide flexibility for changing crude qualities, ensuring compliant and economically robust refinery operations.

Worley Comprimo has carried out an evaluation of technologies allowing 99.8+% sulphur recovery for an Indian refinery case. The TopClaus process was compared to alternative technologies, focussing on modern technical challenges, investment operation and maintenance costs, as well as CO2 considerations.

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.

Maximising sulphur recovery in a modified Claus SRU/TGTU requires controlling and monitoring COS and CS2. Leveraging decades of monitoring experience, AMETEK Process Instruments discusses the formation, impact and monitoring of COS and CS2.

The Sulphur Institute celebrates its 65th anniversary this year. In this article the organisation describes its lasting legacy and global impact.

Continuous monitoring of sulphur recovery units (SRUs) has proven to be an excellent tool for energy optimisation and emissions reduction, yielding financial incentives in the form of CO2 credits and sustainability. Even in markets with limited CO2 credits, significant economic benefits can still be realised through reduction in utility consumption, as demonstrated by a recent collaboration between Worley Comprimo and PRefChem in Malaysia.

CSV Midstream Solutions says that it has successfully completed commissioning and commenced operations at its Albright gas plant in northern Alberta, tapping into the Montney shale gas field. The new 150 million scf/d sour gas plant with associated sulphur recovery represents the first of its kind to be built in Alberta in more than a generation.

India’s Megha Engineering and Infrastructures Limited (MEIL) has won a $225.5 million contract from the Kuwait Oil Company (KOC) for setting up a new gas sweetening and sulphur recovery facility at West Kuwait oilfields. The project, to be developed on a build-own-operate basis with a buyback option for KOC, includes design, construction, operation and maintenance. It will be completed in two years, followed by a five-year operation and maintenance phase.

YPF says that its modernisation of the Luján de Cuyo refinery has taken a step forward with the installation of a hydrodesulphurisation reactor, designed to remove sulphur compounds from diesel fuel by means of a catalytic process using hydrogen. The installation forms part of the refinery’s New Fuel Specifications (NEC) project, intended to produce of fuels with a lower environmental impact. The new reactor was built in Mendoza by IMPSA. With a length of 38 meters and a weight of 456 tons, it was moved from Godoy Cruz to the YPF plant in a logistic operation that involved Vialidad Nacional, Mendoza Police and local authorities. It will now be integrated into the HDS II unit, designed to reduce sulphur content in diesel to 10 parts per million, in line with current environmental requirements. The NEC plan includes new process units, such as H2 II and SE33, the adaptation of existing facilities and the improvement of auxiliary services. The project, already 85% complete, will allow all the diesel oil produced in Luján de Cuyo to comply with the highest emission requirements.
