The first half of 2021 has been characterised by tight supply in the ammonia market, exacerbated by plant outages in Europe, Trinidad, Saudi Arabia and Indonesia. At the same time, higher spot demand has fuelled significant price increases in both the eastern and western hemispheres. Low inventories and reduced export availability in the Far East forced Indian phosphate producers and industrial consumers of ammonia to source product from other locations.
Johnson Matthey’s latest methanol synthesis catalyst, KATALCO™ 51-102, was introduced in 2018 to offer improved catalyst stability and therefore higher end-of-life activity and extended lifetimes than conventional methanol synthesis catalysts. Since launch, KATALCO 51-102 has been successfully installed in two methanol plants and a third is planned for later in the year. In this article Johnson Matthey provides an update on the proven performance of KATALCO 51-102 during lab and pilot scale testing as well as in customer plants. The application of catalysts made using the KATALCO 51-102 technology for methanol synthesis via new ‘green’ routes, such as using captured and purified CO2 in conjunction with ‘green’ hydrogen, is also discussed.
Johnson Matthey and MyRechemical have formed an alliance to commercially develop waste to methanol technology. In this article, two different approaches to waste disposal and chemical production are analysed: a post combustion scenario with waste incineration and hydrogenation of the CO2 recovered from flue gas to produce methanol, and a precombustion approach with waste gasification followed by conversion of synthesis gas into methanol.
MegaZonE™ is a newly introduced layered loading technology for boiling water-cooled reactors used for methanol synthesis. This new concept is one of the latest results of the long-standing collaboration between Air Liquide Engineering & Construction and Clariant Catalysts to improve the methanol process flowsheet and optimise catalyst performance in the complete reactor system.
Ammonia markets continue to be dominated by unplanned outages in Saudi Arabia (where the SAFCO 4 and one of the Ma’aden ammonia plants are both down, removing 2.3 million t/a of merchant ammonia from the market). This comes on top of other shutdowns earlier in the year on Trinidad, in the US and Australia.
A round-up of current and proposed projects involving non-nitrogen synthesis gas derivatives, including methanol, hydrogen, synthetic/substitute natural gas (SNG) and gas- and coal to liquids (GTL/CTL) plants.
The Chemical & Process Technologies business unit of thyssenkrupp Industrial Solutions is celebrating a milestone in 2021. It is one hundred years since engineer and entrepreneur Friedrich Uhde founded his own plant engineering company in a barn at his parents-in-law’s farm in Dortmund-Bövinghausen on April 6th, 1921. Now, in this centenary year, the origins of the firm are to become visible in its name again: thyssenkrupp is changing the business unit’s name to thyssenkrupp Uhde.
February saw ammonia prices jump due to a series of plant outages, including EBIC in Egypt, and several plants in North America, including two on Trinidad; the 760,000 t/a Nutrien 4 plant and 500,000 t/a Tringen 2 plant, both due to gas shortages, as well as Yara and BASF’s 750,000 t/a unit at Freeport, Texas.
The ammonia industry has always dealt with fluctuations in supply and demand as well as volatile feedstock and energy costs. The unexpected global pandemic that started in 2020 has injected a higher degree of uncertainty for ammonia manufacturers’ operating costs and product demand for fertilizer. W. Poe of AVEVA discusses how advanced process control systems can help ammonia producers turn economic uncertainty into a competitive advantage.
A recent report from BloombergNEF (New Energy Foundation) looking ahead to 2050 argues that green hydrogen can be cheaper than natural gas. It finds that ‘green’ hydrogen from renewables should become cheaper than natural gas (on an energy-equivalent basis) by 2050 in 15 of the 28 markets modelled, assuming scale-up continues. These countries accounted for one-third of global GDP in 2019. In all of the markets BNEF modelled, ‘green’ hydrogen should also become cheaper than both ‘blue’ hydrogen (from fossil fuels with carbon capture and storage – CCS) and even ‘grey’ hydrogen from fossil fuels without CCS. The cost of producing ‘green’ hydrogen from renewable electricity should fall by up to 85% from today to 2050, the report predicts, leading to costs below $1/kg ($7.4/MMBtu) by 2050 in most markets. These costs are 13% lower than BNEF’s previous 2030 forecast and 17% lower than their previous 2050 forecast. Falling costs of solar photovoltaic (PV) electricity are the key driver behind the reduction; BNEF now believes that PV electricity will be 40% cheaper in 2050 than they had thought just two years ago, driven by more automatic manufacturing, less silicon and silver consumption, higher photovoltaic efficiency of solar cells, and greater yields using bifacial panels.
