Contract awarded for nitric acid plant

NextChem has also announced that its nitrogen technology licensing division Stamicarbon, has been a licensing contract and the project development process for a new nitric acid plant in China. The project entails the application of Stamicarbon’s state-of-the-art mono-pressure technology, part of NX STAMI™ Nitrates series, which uses oxygen instead of air as feed for the process, enabling high energy recovery and low operational costs. NextChem says that the award builds on the Group’s longstanding expertise in nitrogen technologies and reflects its commitment to industrialising efficient, low-emission solutions for the agricultural supply chains.

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.
