This article dives into Chemetics’ rich history and key innovations that have shaped and moulded the industry.

Venkat Pattabathula, a member of the AIChE Ammonia Safety Committee, reports on the American Institute of Chemical Engineers’ (AIChE) Safety in Ammonia Plants and Related Facilities Symposium held in San Diego on 8-12 September 2024.

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.

Stefano Cicchinelli and Carmen Perez of Stamicarbon (MAIRE) explore the latest advancements in tertiary abatement technologies, their implementation in nitric acid plants, and the implications for the fertilizer industry.

As the industry pushes towards more sustainable practices, ammonia is emerging as a promising alternative fuel for ships. Effective management of by-product NOx, NH3 and N2 O emissions from the combustion of ammonia is crucial to the success of ammonia as an alternative fuel. A new catalyst has been developed by Enercat to treat these three molecules in one bed. Jean-Rémi Stephany and Emmanuel Rohart of Enercat – Alsys Group report on this new technology which has been developed in marine ammonia combustion engine conditions.

Innovative catalyst systems from Heraeus and Łukasiewicz Research Network – New Chemical Syntheses Institute contribute to reach climate goals by reducing N2 O emissions during nitric acid production. Dr Uwe Jantsch and Jens Hesse of Heraeus Precious Metals report on the process performance results achieved for N2 O reduction in nitric acid production using FTC gauze systems and iron oxide based secondary catalysts.

Join us at the CRU Sulphur + Sulphuric Acid 2024 Conference and Exhibition in Barcelona, 4-6 November, for a global gathering of the sulphur and sulphuric acid community. Meet leading market and technology experts and producers, network, share knowledge, and learn about market trends and the latest developments in operations, process technology and equipment.

In this case study, CS Combustion Solutions presents a comprehensive strategy for the capacity enhancement and optimisation of a sulphuric acid plant that was facing several operational challenges.

This troubleshooting case study describes an incident at one of the sulphur recovery units at BPCL Kochi Refinery, India. Following a maintenance turnaround of the unit in 2022, unusually high H2 S and SO2 were observed at the outlet of the Claus section. This created an additional load on the tail gas reactor, which led to frequent plugging in the quench column and frequent outages in the tail gas unit, creating environmental and reliability issues in the unit. The activities to identify the root cause of the incident are described and the measures to solve the problem are shared.

Large-scale ammonia cracking technology and catalysts will enable the full potential of ammonia to be realised as industries transition towards low carbon energy. In this feature we report on the current status of ammonia cracking processes and catalysts.
