Metso launches Cu POX leaching process for copper extraction industry - solution maximises copper recovery while reducing environmental impact
NextChem (Maire) is awarded a three-year engineering and technology services contract by Satorp in Saudi Arabia to improve energy efficiency and carbon footprint
Days 2 and 3 of the CRU’s 38th Nitrogen+Syngas 2025 Expoconference turned to the technical sessions, organised in three parallel streams covering: green ammonia technology, nitric acid and ammonium nitrate, plant operations and reliability, urea technology, digitalisation, carbon capture, emissions reduction and sustainable fertilizer production, and fertilizer finishing.
Syngas generation units (SGU) represent a large portion of the capital and operational expenditure of ammonia plants and are critical from a mechanical reliability standpoint. Related capex/opex optimisation and mitigation of possible operational problems are key targets for ammonia plant owners. Giovanni Manenti introduces NITROQUENCH® technology which focuses on these key targets for ammonia SGU.
Revamping aging urea plants with the latest urea technology brings many benefits. Not only can greenhouse gas emissions be reduced, but the overall performance and sustainability of these facilities can also be optimised. Hiroo Kunii of Toyo Engineering Corporation discusses TOYO’s approach to urea plant revamping.
The ‘golden batch’ refers to stable periods at production plants that consistently generate high quality NPK products at high output. Yara’s Golden Batch digital tool digitises and stores past data from optimal production runs, making these easy to retrieve and implement again in future. Yara’s Marianne Ytterbø provides an overview of this novel digital tool, explains how it was developed, and highlights key benefits.
Aparna Saiju and Nishevitha U G of SLB-MPS explore the concept of energy optimisation using power recovery turbine (PRT) technology in amine sweetening units, focusing on its potential benefits, implementation strategies, and environmental implications.
Addressing the ‘leaky’ nature of nitrogen fertilizers is a longstanding priority for growers, fertilizer producers and retailers alike. Dr Karl Wyant, Nutrien’s Director of Agronomy, examines the valuable role enhanced efficiency fertilizers (EEFs) can play in improving nitrogen use efficiency.
Ammonia has been recognised as an advantageous hydrogen and energy carrier. This article focuses on the use of ammonia as fuel in steam reformers and ammonia crackers in order to reduce or completely eliminate direct CO2 emissions. Ammonia combustion knowledge is especially important for ammonia crackers with respect to the recycling of unconverted ammonia. Air Liquide is constructing an industrial scale pilot plant in Antwerp, planned to be operational in 2024, that will be used to demonstrate ammonia cracking and combustion in a process furnace with a multiple burner configuration.
Sulphur Experts outline the steps required to determine optimised SRU incinerator operating conditions. Although a proper determination of the ideal SRU incinerator operating conditions for any given facility is complicated by a combination of inconsistent permitting standards and poor understanding of the role of the SRU incinerator, the payoff for incinerator optimisation is a significant decrease in natural gas usage with corresponding savings in operating costs, a decrease in CO2 emissions, and a simultaneous reduction in NOx and SO3 emissions.
