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.

Casale’s fluid bed granulation tail gas treatment for nitrogen-based fertilizer employs double temperature scrubbing technology, which handles the granulator exhaust air separately from the cooler exhaust air. The technology can combine dust removal with ammonia abatement in the same installation to meet strict tail gas limitations such as 10 mg/Nm3 for dust and 10 mg/Nm3 for ammonia. Ken Monstrey of Casale explains the key features of the Casale scrubbing technology.

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.

Refinery sour water strippers are an often overlooked resource of low GWP ammonia. Martin A. Taylor and Charles L. Kimtantas of Bechtel Energy Technologies and Solutions, Inc. (BETS) show the results of a study on reusing an existing SWS as one of the major systems in a SWSPlus unit for the recovery of ammonia for sale. Relative cost factors will compare a complete SWSPlus unit versus reusing an existing SWS.

Optical gas imaging technology, enhanced by artificial intelligence, offers a groundbreaking approach to monitoring SO2 emissions in real time. Andrés Russu of SENSIA introduces SENSIA’s RedLook solution which offers fully autonomous, 24/7 continuous monitoring of SO2 leaks, providing industries with the tools they need to maintain environmental integrity and operational safety.

As Comprimo celebrates its 100th anniversary, we explore the group’s history from its earliest days in the Netherlands in the 1920s to its current status as a global leader in gas treatment and sulphur recovery technology.

A plant operating a spent acid decomposition furnace as part of its sulphuric acid production facility desired to increase acid production primarily by processing additional spent acid while making minimal modifications to the plant equipment and operations. The Messer solution entailed introducing oxygen in two steps, both as an enrichment to the combustion air and by direct injection into the furnace. The resulting performance improvements exceeded the project objectives for acid production and spent acid decomposition, without increasing NOx emissions. This paper provides a summary of the system start-up and tuning and presents the resulting improvements and lessons learned.

A review of the current slate of plans for green and blue ammonia production.

The production and use of nitrogen fertilizers are responsible for around five percent of global greenhouse gas (GHG) emissions. The fertilizer industry will need to drastically cut these emissions by 2050 as part of its contribution to the 1.5 °C global warming target. Yet around 48 percent of the global population rely on crops grown with nitrogen fertilizers. Guaranteeing food security, by continuing to supply affordable crop nutrients at scale, while transitioning to a low-carbon future, is therefore the collective challenge for the global fertilizer industry and world agriculture.

The need for immediate climate action and cuts in carbon emissions has never been more urgent, especially in a world where ecosystems are increasingly under threat. The production of green fertilizers offers a clear route to achieving these goals by decreasing the chemical industry’s reliance on fossil fuels. Stamicarbon’s Carmen Perez, Rolf Postma and Nikolay Ketov outline the company’s innovative and integrated approach to green fertilizer technology.
