Stamicarbon has been awarded a contract for the licensing, process design package (PDP) and the supply of proprietary equipment for a new urea plant in Eastern China.

Potash and phosphate have been added to the updated 2025 List of Critical Minerals published in the US Federal Register on 6th November.

The 2026 Nitrogen+Syngas Expoconference will take place in Barcelona, Spain, from 9-12 February. Join us at this industry leading event where leading market and technology experts and producers will gather to connect, share knowledge and learn about the latest developments in operations, technology, processes and equipment.

Maximising sulphur recovery in a modified Claus SRU/TGTU requires controlling and monitoring COS and CS2. Leveraging decades of monitoring experience, AMETEK Process Instruments discusses the formation, impact and monitoring of COS and CS2.

The Sulphur Institute celebrates its 65th anniversary this year. In this article the organisation describes its lasting legacy and global impact.

Joel Cantrell of Bryan Research & Engineering and Clay Jones of INEOS GAS/SPEC re-evaluate the historical practice of intentionally adding strong base such as caustic (NaOH) to amine with the purpose of improving performance and reducing corrosion by “neutralising” heat stable amine salts (HSAS) which have accumulated in the amine.

Platinum-promoted honeycomb catalyst bricks offer function as total oxidation catalysts that convert all oxidisable species under appropriate temperature and oxygen conditions. P&P Industries presents a case for a H2S-rich gas stream – relevant to the fibre industry, Claus offgas treatment, and other chemical sectors.

A full sulphur pit turnaround and rehabilitation is typically a once in a lifetime experience for refinery personnel. Specialists in sulphur pit turnarounds, Gavin Palmer of Brindley Engineering, Tom Kline and Bob Hall of Structural Technologies have compiled a database based on multiple sulphur pit turnarounds to identify typical deficiencies in mechanical systems, along with improvements to enhance operability, restore functionality and meet all codes/standards and best practices.

Continuous monitoring of sulphur recovery units (SRUs) has proven to be an excellent tool for energy optimisation and emissions reduction, yielding financial incentives in the form of CO2 credits and sustainability. Even in markets with limited CO2 credits, significant economic benefits can still be realised through reduction in utility consumption, as demonstrated by a recent collaboration between Worley Comprimo and PRefChem in Malaysia.

MHI has successfully completed the Ghorasal Polash Urea Fertilizer Project in Bangladesh - the country’s largest fertilizer complex. Key features of the project include: the KM CDR Process™ that captures CO2 , cuts emissions and boosts urea output; an energyefficient granulation unit using a bulk flow cooler to reduce power demand; and reinforced digital safety management.
