As the world focuses on clean fuels for the 21st century, there is an emerging opportunity to use ammonia as a source of hydrogen. Hydrogen fuel cells are expected to play a significant role as part of a clean energy portfolio. T2M Global and its development partner, SAFCell, are collaborating to develop a modular system to produce hydrogen from ammonia using a novel solid state separation system that does not require pressure or solvents. P. Patel of T2M Global, C. Chisholm of SAFCell and V. Pattabathula of Incitec Pivot explain the challenges, the opportunities and the current status of this new technology.

West Texas Intermediate (WTI) forward oil prices for May dropped into negative territory during mid-April, on fears of lack of storage capacity to deal with the excess production. Forward prices for June were also nosing to equally unprecedentedly low levels.Elsewhere, Brent Crude spot prices dropped to $20/bbl, a fall of $50/bbl from the start of 2020.

What are the limits for future single stream sulphuric acid plant capacities? H. Storch, C. Bartlett, and S. Mohsler of Outotec discuss design considerations for large capacity sulphuric acid plants with reference to the world’s largest acid plants built to date.

Tecnimont SpA has signed an EPC contract worth approximately e200 million with Gemlik Gübre Sanayii Anonim Sirketi for the construction of a new urea and urea ammonium nitrate (UAN) solutions plant at Gemlik, 125 km south of Istanbul. The plant will have a capacity of 1,640 t/d of granular urea and 500 t/d of UAN, and will be based on Stamicarbon urea technology, a fully owned subsidiary of the Maire Tecnimont group. The scope of work includes engineering, supply of all equipment and materials and construction and erection works. Project completion is planned within about three years of the contract beginning.

Haldor Topsoe has launched a new methanol synthesis catalyst, MK-181 PRIME, based on new technology developed via close study of copper-zinc interactions on the catalyst surface.

Olefins production from methanol, particularly in China, has come to dominate the methanol market over the past few years. However, environmental and market concerns complicate the outlook there.

As existing facilities grow older, service requirements increase. Equipment needs to be low maintenance and back in operation quickly after service and repair. Technology licensors are expanding their technical services with new digital tools, using digitalised expertise with real time insights and data driven analytics to boost chemical production and ensure that equipment operates reliably and efficiently, while maintaining product quality.

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.

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.
