Phosphogypsum is finding increasing use in plaster and cement manufacture, roadbed construction and afforestation. We look at how previously unwanted solid waste generated by the phosphate industry is being turned into a valued resource.
Shutdowns in technical ammonia capacity due to the pandemic have contributed to make 2020 a turbulent year for ammonia markets, but plant shutdowns, strong fertilizer demand and a shortage of new merchant ammonia capacity are contributing to finally removing the burden of overcapacity.
As industry trends add pressure to optimise processes, new digital technologies for roundthe-clock, data-driven decision-making can help plants boost production efficiency without time-consuming manual analysis or large-scale investment. Here, Dr S. Werner of Navigance explores their potential and shares the difference they are already making.
From new materials of construction and improved equipment designs to the latest digital tools, Casale, thyssenkrupp Industrial Solutions, Saipem, TOYO and Stamicarbon report on some of their latest achievements.
Copenhagen Infrastructure Partners (CIP) has unveiled plans to build Europe’s largest power-to-ammonia facility at the Danish port of Esbjerg, based on electricity from offshore wind turbines. The company said the plant will consist of 1GW of electrolysis capacity, capable of supplying sufficient hydrogen to produce 300,000 t/a of ammonia, and that the ammonia will be used as both as agricultural fertiliser and as fuel for the shipping industry. Excess heat generated in the process would be used to provide heating for around one third of local households in communities around the plant, to be sited on the west coast of Denmark. The company has signed a memorandum of understanding for the project with companies from both the agriculture and shipping sectors, including Danish Crown, Arla, DLG, Maersk and DFDS Seaways. CIP anticipates that it would cost approximately $1.2 billion to build the facility. They are currently seeking investors for the project and expect that the investment decision would be reached by 2023. The plant could enter commercial operations in 2026.
Suddenly it’s a good time to be a sulphur producer again. Sulphur prices started 2020 at a low point of $40/t, a level not seen for a decade or more. However, after a slight recovery when the pandemic hit and refineries began reducing production, since August the market trend has been rapidly upwards, now approaching levels of $200/t that have not been seen for a couple of years.
The profound demand shock caused by Covid-related lockdowns has had a major impact upon the refining industry. Run rates have been at low levels in North America and Europe, and a new wave of rationalisation is under way, at the same time that capacity continues to grow in Asia. Will this spur diversification into petrochemicals and low carbon options for Atlantic basin refiners?
Sour gas processing presents a number of unique challenges, especially at high levels of hydrogen sulphide and carbon dioxide content.
Automatic identification and optimum online monitoring using sonic velocity measurements can now be used to determine the concentration of both sulphuric acid and oleum.C. Kahrmann and T. Knape of SensoTech report on a new user-friendly method of measurement providing a significant step towards automated process control.
