A new cost-effective alternative sulphur technology, providing a simple and robust process to achieve an overall sulphur recovery efficiency of 99.9+% is being developed by Saudi Aramco. J. P. O’Connell and I.A. Alami of Saudi Aramco discuss the new technology, its benefits and current stage of development.
State-of-the art technologies offered by thyssenkrupp, Casale and Stamicarbon are helping make nitrates production more secure and sustainable.
Yara and Lantmännen have signed an agreement to bring fossil-free mineral fertilizers to market.
The production of syngas from hydrocarbon feedstock uses a number of catalytic steps to increase efficiency and maximise conversion while minimising energy consumption. In this article we report on the latest developments in water gas shift catalysis from Johnson Matthey, Clariant and Topsoe, and shift converter design from Casale.
The Bia Energy Operating Company says that it is evaluating a $550 million blue methanol plant at the port of Caddo-Bossier in Shreveport, Louisiana. The unit would have a capacity of 530,000 t/a of methanol using natural gas feedstock with downstream carbon capture, reducing CO2 emissions by more than 90% compared to other methanol plants. The company is expected to make a final decision in 1Q 2022, with construction expected to last approximately two years, and commercial operations to begin soon after.
Decreasing the carbon intensity of sulphur recovery is one of the many actions that operators can take to help meet their climate ambitions. It is also becoming increasingly rewarding financially because of the rising cost of carbon emissions. In this article, G. Kidambi of Shell Projects & Technology demonstrates the potential to cut the carbon intensity of tail gas treating units by more than 50% through swapping to the latest SCOT ULTRA amine solvent and catalyst technologies.
As the world looks to a lower carbon future, refineries are having to examine their operating models, and look to, for example, renewable hydrogen production for desulphurisation technologies.
Global demand for oil products has seen strong recovery in 2021, but depressed kerosene demand from the aviation sector continues to be a major barrier to full recovery, according to data and analytics company GlobalData. The company’s analysis of oil product flows suggests that when kerosene is excluded, oil product demand in Q3 2021 had fully recovered compared to the same period in 2019. However, demand for kerosene, mostly used for jet fuel, has hovered at around two thirds of pre-Covid-19 levels throughout the year, and when that is taken into account, total oil product demand was 3% below pre-Covid levels for Q3 2021. Kerosene demand saw the greatest impact from Covid-19 due to restrictions on air travel. While the sector recovered, to an extent, in the second half of 2020, recovery stalled in 2021 due to new waves of infections and restrictions, with new restrictions linked to the Omicron variant likely to have hit demand again in Q4.
Sulphur processing from sour gas fields dominates regional production, but the geographical remoteness of the area from end use markets and restrictions on sulphur storage means that producers often opt to reinject acid gas into oil and gas wells.
Like the vital nitrogen fertilizer they handle, seasonal cheer will be in short supply for Europe’s ammonia producers and buyers this festive season, after many difficult months in which upward price trajectories showed no sign of slowing.
