UreaKnowHow.com reviews the main production options for incorporating sulphur into urea, the world's most widely applied commodity fertilizer.

Metso describes how digital solutions can profit from the deep integration of using a digital process twin in sulphuric acid technology, helping to improve operation, monitoring and reporting.

IPCO highlights the reasons for converting sulphur into a solid form, and compares two of the technologies most commonly used to achieve this.

AMETEK Process Instruments has collaborated with Worley Comprimo, part of Worley’s Technology Solutions, to provide sulphur recovery unit (SRU) stakeholders with critical analytical measurements combined with advanced burner control technology to deliver enhanced automated air control management. The companies say that their 2ACT™ Solution is a fully automated system that minimises SRU upsets, enhances reliability, and delivers strong returns on investment. At the heart of this partnership, the innovative 2ACT™ Solution offers an all-in-one approach to advanced air control – significantly boosting SRU performance and efficiency while reducing operational costs. 2ACT uses AMETEK’s IPS-4 ultraviolet and infrared analyser to measure H2 S, CO2 , NH3 , H2 O and total hydrocarbons (THCs) by continuously sampling the acid gas upstream of the SRU. The change in air demand requirement is then calculated, with main and trim air adjustments implemented automatically by the feed forward control scheme designed by Worley Comprimo. The companies say that the benefits of the 2ACT Solution include maintaining an optimal H2S to SO2 ratio at the outlet of the Claus Plant to maximise recovery efficiency, mitigating damage to tail gas treatment unit (TGTU) components, lowering SO2 emissions and carbon footprint with improved uptime and plant throughput.

Topsoe has been selected by Zhongneng Yida New Energy Co., Ltd to deliver technology for production of sustainable aviation fuels (SAF) at a new facility to be located at the city of Shijazhuang in the Shenze Economy Development Zone of Hebei province. Zhongneng Yida plans to export the produced SAF to European and local Chinese markets. Topsoe will provide its HydroFlex® technology and catalysts as part of the agreement. The facility will produce 400,000 t/a of SAF, utilising used cooking oil for the feedstock.

In other news, AMETEK says that its 993X series of analysers, encompassing the 993X and 9933, are now ATEX and IECEx Zones 1 and 2, and ETL (North America) Class I Division 2 compliant for use in hazardous locations with ambient temperature up to +60ºC. Built with IP66 rated enclosures, the 993X analysers can be installed outdoors, or in minimally temperature-controlled enclosures, reducing both capital and operating costs.

Eurotecnica's Euromel® Melamine Technology selected by Zhongneng Chemical Co Ltd for new world-scale facility

A round-up of current and proposed projects involving non-nitrogen synthesis gas derivatives, including methanol, synthetic/substitute natural gas (SNG) and gas- and coal to liquids (GTL/CTL) plants.

This year’s International Methanol Technology Operators’ Forum (IMTOF) was held at the Holiday Inn Regents Park hotel, London, from June 15 to 18.

VK Arora of KPI examines the technical and operational challenges of decarbonising legacy and new ammonia plants, drawing on a European case study of full-scale conversion supported by robust process and integration design. It also presents three US case studies exploring partial strategies, such as green hydrogen blending and oxygen enrichment, to reduce CO2 emissions and improve throughput. Together, these examples highlight a phased, cost-effective approach to decarbonisation, with blue hydrogen serving as a near-term transitional feedstock.
