Overall the market finds itself in a period of illiquidity, and is exposed to further uncertainty in 4Q because of the European energy crisis. Spiralling natural gas costs in Europe, with Dutch TTF gas prices trading around e200/MWh, are forcing European fertilizer producers to close ammonia capacity and buy in from overseas.
Temperature dependent rate constants for the hydrolysis of CS2 and COS across Claus Al2 O3 and TiO2 catalysts are valuable tools for the design and optimisation of new, as well as existing, sulphur recovery units. In this context, Alberta Sulphur Research Ltd (ASRL) has measured CS2 and COS hydrolysis rates over a range of temperatures for both Al2 O3 and TiO2 catalysts under start-of-run and, more recently, end-of-run first converter conditions. In this article Christopher Lavery, Dao Li, Ruohong Sui, and Robert A. Marriott of ASRL report on their methodology and the utility of the kinetics calculated from their data and draw comparisons between the start-of-run and end-of-run results.
On February 27th, in a speech to the Bundestag, Germany’s chancellor Olaf Scholz described the events then unfolding as a “zeitenwende” – a historical turning point. He was speaking of German foreign and security policy, but it seems likely that Russia’s February 24th invasion of Ukraine may end up marking a break with the past in many different ways. Last issue’s Editorial was written when Russia’s ‘special military operation’ was still only a few days old, and the situation was still very fluid. Two months on, and for all of the uncertainties remaining, some glimpses of the way that things are changing are becoming clearer.
Yara and Mosaic shocked markets with a settlement of $1,625/t c.fr for April, up $490/t on March, and the highest ever price recorded at Tampa, as the removal of Russian and Ukrainian ammonia supply impacted global prices, and Baltic rates soared to $1,500/t. However, April saw some of the global dislocations caused by the Russian conflict begin to ease, while the high prices saw buyers in the US delay purchases, leading to the Tampa price falling back $200/t for May loadings.
The ammonia market, already seeing record pricing in the wake of the winter’s gas price squeeze, is braced for even higher pricing in the wake of the Russian invasion of Ukraine. The impact upon gas prices has been most marked, with rates of over $65/MMBtu seen in European forward pricing as the threat of a cessation of Russian gas exports loomed. This will undoubtedly lead to widespread idling of ammonia capacity in Europe.
INEOS says that it is aiming to forward its plans for a ‘net zero’ future for its Grangemouth site in Scotland by inviting major engineering design contractors to tender for the next stage of the design of a world scale carbon capture enabled hydrogen plant and associated infrastructure.
The CRU Nitrogen + Syngas Conference returns to Berlin for a live event from 28-30 March 2022. The conference will be run as a hybrid event giving participants the option to attend live in-person or online via the virtual platform.
New innovations, services and latest technologies to improve the operation and reliability of steam methane reformers from AMETEK Land, Kontrolltechnik, BD Energy Systems, Koch Engineered Solutions, and Quest integrity.
Ricardo L. Sepulveda of PegasusTSI reviews options to decrease the CO2 footprint of a fertilizer industrial complex and illustrates the technical and economic feasibility of utilising clean energy from a sulphuric acid plant in a fertilizer complex to produce green hydrogen, which in turn can be used to produce green methanol or green ammonia.
The production of syngas from hydrocarbon feedstock uses a number of catalytic steps to increase efficiency and maximise conversion while minimising energy consumption. In this article we report on the latest developments in water gas shift catalysis from Johnson Matthey, Clariant and Topsoe, and shift converter design from Casale.
