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.

CRU expects sulphur prices to be supressed in early 2024 by high port inventory and limited phosphate export business. However, affordability continues to support raw materials purchases and leaves room for price increases, especially if downstream production picks up as expected and sulphur stock drawdown slows.

Pyrite roasting as a source of sulphuric acid continues to be a significant, albeit minor sector of the overall acid market.

Cobalt-molybdenum catalysts are integral components of tail gas units, playing a vital role in reducing harmful sulphur dioxide emissions arising from Claus sulphur recovery units. Effective activation of these catalysts is essential for their optimal performance. In the first part of this two-part article, Michael Huffmaster, Consultant, explores CoMo catalyst activation at low pressure, focusing on sulphiding reaction pathways and the impact of temperature and the composition of the sulphiding media on reaction kinetics.
