The Sulphur Institute is holding its annual meeting in Chicago, Illinois this year from April 20th-22nd.

Applied Analytics discusses potential improvements made possible with data and analytical measurements fed into improved mathematical models to produce a more proactive approach to control and better performance of sulphur recovery units, AMETEK Process Instruments explains the benefits of feed forward control, SICK reports on reliable continuous emission monitoring systems and WIKA introduces a new purge-free system to measure refractory temperature in the Claus reaction furnace.

This year appears to be determined to illustrate the limitations of forecasting. Projecting trend lines into the future, looking at expected completion dates for major projects and global economic projections are all worthwhile activities, and can provide valuable insights for business people, but any prediction is apt to be derailed by what one of our prime ministers supposedly once described airily as; “events, dear boy, events.”

Although North America is no longer the world’s largest sulphur exporter, it remains a major producer and consumer, and there are still significant exports and imports of sulphur into and out of the region.

Fluor/GAA continue to strive to improve the performance of the D’GAASS out-of-pit liquid sulphur degassing technology based on commercial operating experience and ever-changing environmental emissions regulations. T. Chow and S. Fenderson of Fluor Energy & Chemicals/ Goar, Allison & Associates discuss operating experience that has led to the improvements of the new patent-pending third generation D’GAASS 3G technology.

China’s copper industry is facing difficulties caused by the coronavirus outbreak in the country. Prolonged factory closures, particularly in Hubei province, at the centre of the outbreak, as well as neighbouring Guangdong and Zhejiang, also badly affected, have caused a slump in demand for copper domestically as copper fabricators remain on extended closure. However, smelters have resisted cutting production. Daye Nonferrous, based in Huangshi at the centre of coronavirus outbreak, continues to operate at 80% of its 600,000 t/a capacity for 1Q 2020, according to the company, in spite of quarantine and transport restrictions which have reduced truck shipments to the smelter – Daye is reportedly still able to receive copper concentrate shipments via the Yangtze River to Huangshi port.

Claira Lloyd, Sulphur Editor and Sulphur Fertilizers Team Leader, Argus Media, assesses price trends and the market outlook for sulphur.

Kuwait is in the middle of a major overhaul and expansion of its refining capacity, as well as boosting LPG output and sour gas processing.

J. C. Bourdon, F. H. Brown and P. J. Photos of Streamline Innovations Inc. present the development and commercialisation of the Valkyrie™ process, which employs new chemistries and advanced control systems to remove H2 S from natural gas at size scales ranxging from single wells to entire fields, providing an operationally sustainable and commercially attractive alternative to standard H2 S removal technologies.

The Abu Dhabi National Oil Co. (ADNOC) has awarded two EPC contracts with a total value of more than $1.65 billion for the offshore Dalma sour gas development, 190 km northwest of Abu Dhabi city. Dalma is one of the fields in the offshore Ghasha ultra-sour gas concession, which ADNOC views as central to the UAE achieving self-sufficiency in domestic gas supplies.
