Sulphur is becoming an increasingly important crop nutrient, due to a combination of lower airborne sulphur emissions, the increasing prevalence of high analysis fertilizers, and higher cropping intensities.

Although the number of new sour gas developments has slowed in recent years compared to the large boost of the previous decade, sour gas projects continue to be a major source of new sulphur production.

Considering the current shift to produce biofuels instead of conventional oil products, M. van Son of Comprimo discusses the impact that this may have on the ability to process the sour water acid gas streams produced in existing or new sour water strippers.

Developments in sulphuric acid technology and engineering know-how are highlighted by recent project case studies from DuPont Clean Technologies, Metso Outotec and thyssenkrupp Uhde.

The Valkyrie™ process was first introduced as a reborn version of redox technology for treating H2 S in natural gas processing.In this article Streamline Innovations Inc. highlights some of the new developments and successful applications of the Valkyrie process and its redox technology, in both gas and water streams.

M. Rameshni and S. Santo of RATE discuss different sour water stripping gas processing options, depending on contaminants in the sour water streams and site-specific requirements.

New low-cost metal oxide solid scavengers for hydrogen sulphide (H2 S) removal from wet and dry natural gas have been developed and deployed at commercial scale. The desulphurisation process uses a proprietary sorbent chemistry to achieve a high sulphur capacity and removal efficiency. G. Alptekin, F. Kugler and M. Schaefer of SulfaTrap LLC describe the new technology and its performance.

Major fertilizer industry players such as Stamicarbon, Nutrien and CF Industries are ramping up investment in ‘green’ and ‘blue’ fertilizer production. Consequently, low-carbon production technologies are being scaled-up and deployed commercially.

Buss ChemTech AG offers the international phosphate industry a robust solution to create added-value products from fluorosilicic acid (FSA). Thomas Dahlke, the head of the company’s process engineering department, and Emre Sen, sales manager for fluorine technologies, explain how this can be done in a sustainable manner.

Johnson Matthey’s latest methanol synthesis catalyst, KATALCO™ 51-102, was introduced in 2018 to offer improved catalyst stability and therefore higher end-of-life activity and extended lifetimes than conventional methanol synthesis catalysts. Since launch, KATALCO 51-102 has been successfully installed in two methanol plants and a third is planned for later in the year. In this article Johnson Matthey provides an update on the proven performance of KATALCO 51-102 during lab and pilot scale testing as well as in customer plants. The application of catalysts made using the KATALCO 51-102 technology for methanol synthesis via new ‘green’ routes, such as using captured and purified CO2 in conjunction with ‘green’ hydrogen, is also discussed.
