CRU and UniverSUL Consulting, together with the event host, ADNOC, are delighted to welcome you back for MEScon 2024 at the Conrad Abu Dhabi, Etihad Towers from 20 to 23 May 2024.

The Sulphur Institute (TSI) held its World Sulphur Symposium in Charleston from April 2nd to 4th.

The implementation of WSA technology to recover sulphur as sulphuric acid from lean sulphurous off-gases offers significant environmental benefits. These include waste reduction, resource efficiency and reduced overall CO2 e footprint, while also producing profitable sulphuric acid. By embracing such practices, industries can ensure improved or better consumption and production patterns and foster a more sustainable and responsible future. J. Feddersen and S. S. Johansson of Topsoe illustrate these benefits using three distinct industrial applications where WSA technology provides a smarter way to treat sulphurous off-gases. It is not only waste stream management in the three cases, but also reduced transportation of chemicals, reduced opex and reduced CO2 e footprint.

Sulphur prices reached a low point in mid-February, with buyers looking to the tender from Muntajat as well as the return of Chinese buyers following the Lunar New Year holiday for the direction that the market would turn. CMOC’s 5 February tender for 40,000 tonnes of sulphur for early-April arrival was indicated awarded in the upper $90s/t c.fr on supply from the FSU, though details were not confirmed.

China’s drive to build new battery production capacity for electric vehicles and stationary storage is leading to a familiar problem for the Chinese economy; overcapacity.

As environmental SO2 emission regulations become more stringent, tail gas treating options become limited. To potentially achieve lower opex and improved plot plan, utilising a biological desulphurisation process as an alternative to a conventional amine-based TGT unit is becoming of increased interest in the oil and gas industry. At the same time, demands for increased SRU capacity and reliability favour the use of medium and high-level oxygen enrichment.

Falling volumes of sulphur from refining and sour gas could turn Europe into a sulphur importer.

In the final part of this two-part article, Michael Huffmaster , Consultant, presents case study results using a discrete reactor model incorporating heat, mass transfer, and activation reaction kinetics to assess the impacts of these variables on in-bed temperature profile and activation effectiveness. Tailoring gas rate, composition, and temperature progression can achieve in-bed exotherms which improve CoMo catalyst activation effectiveness for low temperature tail gas units.

We report on the key highlights of the annual SulGas® conference, organised by Three Ten Initiative Technologies LLP,, which took place in Mumbai, India, from January 31 to February 2, 2024.

Already the world’s largest exporter of sulphur, Abu Dhabi continues to expand its sour gas production and sulphur output.
