Challenges in the conversion to clean ammonia

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.

Axens expands TGT catalyst production

Axens says that it has completed the expansion of its Axens Catalyst Arabia Ltd site, aimed at providing local and regional partners with the latest tail gas treatment catalysts, in addition to the site’s legacy catalyst hydroprocessing manufacturing capacity. This makes Axens is the first and only company to produce tail gas treatment catalysts in the Middle East. The company says that the expansion consolidates its capacity to serve its regional customers to meet regulatory requirements and maximise sulphur recovery by up to 99.9%, minimising SOx emissions. The production site supplies the region’s refining and gas industries with the latest generation of Axens’ catalysts, capable of operating at lower temperatures than conventional catalysts, and resulting in lower energy consumption.

Hybrid hydrogen-diesel retrofits for greener shipping

lomarlabs, the innovation arm of Lomar Shipping, has announced a strategic collaboration with Newlight, a technology company specialising in hybrid hydrogen-diesel engine retrofits, to accelerate the adoption of cost-effective, lower-emission solutions for the shipping industry. This collaboration will focus on retrofitting conventional diesel engines to operate on a hydrogen-diesel mix, reducing fuel consumption on average by 20% and significantly lowering greenhouse gas emissions. Savings of up to 30% have already been demonstrated in workshop trials and this new collaboration will seek to replicate this onboard vessels.
