It’s a slightly dispiriting fact about the sulphur industry that most of its producers don’t really want it. If you’re a refiner or a sour gas producer, you mainly care about the diesel and gasoline or natural gas that you can process and sell, and the sulphur is just the inconvenient component that the law and your customers force you to remove. But at times when sulphur prices, as they have at the start of this January, reach levels as high as $300/t, then the industry standing joke is that sulphur suddenly stops being a by-product or waste product, and starts to become a ‘co-product’ instead.

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.
Catalytic converters are the heart and hub of sulphuric acid plants. Converter replacement of equipment that has come to the end of its life is an opportunity to make improvements to the performance, productivity, reliability, durability and plant emissions. NORAM discusses design and project execution considerations for SO2 catalytic converter replacement and Chemetics considers the challenges and opportunities of converter retrofits.
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.

China’s private sector Shenghong Petrochemical refining complex is targeting a startup in late November, following the receipt of its first cargo of crude in October. The greenfield refining complex in the eastern Lianyungang petrochemical zone has a capacity of 16 million t/a, including a 320,000 bbl/d crude unit – the largest single stream CDU in China – and a 76,000 bbl/d naphtha reformer. Product capacities include 56,000 bbl/d of gasoline, 41,000 bbl/d of diesel and 32,000 bbl/d of jet fuel. Construction began in mid-2019, delayed from 2018 by late approval of its environmental impact assessment, but has been achieved within two months of the scheduled completion date in spite of the coronavirus pandemic. Shenghong Petrochemical is owned by Eastern Shenghong, a producer of petrochemical products and chemical fibres.
