Toyo Engineering Corporation has developed two new digital solutions, MethaMaster™ and MethaDynamics™ , which enhance the operational efficiency of e-methanol production from variable renewable energy.
The production of urea, a critical component in the fertilizer industry, involves highly corrosive environments, particularly in the high-pressure sections of the process. This necessitates the use of advanced materials that can withstand such aggressive conditions to ensure long life and efficiency of urea production plants. Alleima, Stamicarbon, Saipem and TOYO report on their advanced material and equipment solutions for the urea industry.
CRU’s 38th Nitrogen+Syngas Expoconference will be held on 10-12 February 2025 in Barcelona. The most respected technical event for the global nitrogen and syngas community offers an ideal platform for industry professionals to connect, do business and learn about the latest innovations in operations, technology, process and equipment. The annual meeting attracts a global audience of producers, licensors and materials and equipment providers representing an unparalleled opportunity for business networking and peer-to-peer knowledge sharing.
In October, ammonia benchmarks were more or less stable across the board. West of Suez, supply from Algeria was constrained by an ongoing turnaround at one of domestic player Sorfert’s production units. Still, demand from NW Europe remained quiet, although CF was set to receive a 15,000 tonne spot cargo from Hexagon some time in November, reportedly sourced somewhere in the region of $530/t f.o.b. Turkey. While regional supply appeared tight, steadily improving output from Trinidad and the US Gulf could alleviate recent pressures, with many players of the opinion that Yara and Mosaic could agree a $560/t c.fr rollover for November at Tampa as a result.
An ammonium nitrate industry geared around producing explosives for the mining sector is now being joined by a major urea project and a number of renewables-based products for export of green ammonia.
Ammonia prices could remain stable for the duration of October, with any further increases likely to be capped by a lack of demand. The outlook for November is more positive for buyers, with prices set to ease off once turnarounds at key export hubs are concluded.
In spite of increasing environmental concerns over the use of coal as a feedstock, it continues to provide around one quarter of the world’s ammonia. But in a world that is decarbonising, is there still a future for coal-based capacity?
Urea revamp activities are performed to achieve improvements of the urea plant. Besides the typical capacity increase there are many options to reduce operation costs, increase plant availability or reduce environmental impact. In this article Marc Wieschalla of thyssenkrupp Uhde GmbH provides an overview of some of the options from an EPC contractor point of view.
One challenge of a green revamp by stepwise injection of green hydrogen into existing ammonia/urea complexes is to cover the nitrogen demand for the ammonia synthesis while stepwise reducing the front-end load, usually by applying a cost-intensive air separation unit (ASU). thyssenkrupp Uhde GmbH has developed an advantageous concept whereby, instead of an ASU, the nitrogen gap is closed by the introduction of pretreated reformer flue gas back into the ammonia process, with the side effect to also enhance CO2 production.
In recent years, extensive and severe internal attack has been observed of carbon steel equipment and lines in aqua ammonia service at several Yara manufacturing sites across the globe. In all cases, the damage has a distinct flow-accelerated corrosion (FAC) signature which challenges the current understanding of FAC. All features typically observed for this kind of damage mechanism, that seem to be specific to the NH3 recovery section of ammonia plant, are reported. Upgrading the material of construction for this unit, will solve this failure mode, but a leak would potentially generate health and safety problem for the release of ammonia.
