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.

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.

Muhammad Faisal Faraz and Abdullah Al Balushi of OQBi explain how by implementing a series of technical and process improvements, OQBi has successfully extended the lifespan of its reformer tubes by six years beyond the original design life of 100,000 hours.

Together with Slovnaft, Worley Comprimo has developed a near real-time monitoring dashboard using data sharing via the Cloud. Using a two-year data set containing minute average data, trends and insights were used to optimise performance. This paper describes the main learnings and improvements with respect to energy optimisation, which supports sustainability targets for Slovnaft.

While green hydrogen and green ammonia promise to be important clean energy carriers in future, there are significant challenges to be overcome not only in production storage and transport, but also financially realising the project. Innovate technology from thyssenkrupp Uhde, embodied in standardised, pre-integrated, modularised plant can deliver low cost of ownership and de-risks execution.

Risk analysis tools such as hazard identification (HAZID), is often a first step in broader risk management and is especially valuable for green ammonia, where new technologies and processes introduce novel risks. This article explores various aspects of HAZID, from the basics of hazard identification to unique considerations specific to green ammonia facilities.

In part 5 of this series on stripper efficiency issues we conclude the discussion with a focus on fouling inside stripper tubes.

Days 2 and 3 of the CRU’s 38th Nitrogen+Syngas 2025 Expoconference turned to the technical sessions, organised in three parallel streams covering: green ammonia technology, nitric acid and ammonium nitrate, plant operations and reliability, urea technology, digitalisation, carbon capture, emissions reduction and sustainable fertilizer production, and fertilizer finishing.

Sophisticated control of phosphates production is now possible thanks to the availability of real-time process analysers. The emergence of laboratory robots is also improving process efficiency and delivering cost savings.

Based on 16 years of experience, Muhammad Nabeel Shakir of Fatima Fertilizer Company outlines a methodology to achieve optimum performance of the PGM catalyst and catchment system in nitric acid plants.
