Industrial plants using synthesis gas at elevated temperatures risk metal dusting attack on the equipment, which are typically made of steels or Ni-based alloys. Parameters which impact the metal dusting risk are discussed and factors affecting the material selection and processing are described. One important focus is surface preparation, showing that grinding (40 grit) improves the metal dusting resistance compared to glass bead blasting and brushing. The surface treatment outweighs the impact of welds or the manufacturing route.

Hanwha Corporation and INEOS Nitriles have announced their intention to collaborate in a study for a new low-carbon ammonia facility with carbon sequestration in the USA, with a capacity of more than 1 million tonnes per annum. The location of the plant is yet to be determined. The two companies have agreed heads of terms, under which Hanwha and INEOS will jointly explore the feasibility of a facility to meet the growing global demand for ammonia with low-carbon emissions. A final investment decision is planned for 2026 with planned commercial operation in 2030.

A review of the current slate of plans for green and blue ammonia production.

With all of the focus on low carbon ammonia and methanol developments, one could occasionally be forgiven for forgetting that most of the syngas industry relies upon natural gas as a feedstock, and that gas pricing and availability remain the key determinants of profitability for producers. As our article this issue discusses, even low carbon ammonia is likely to be largely based on natural gas, albeit with carbon capture and storage, at least for the remainder of this decade.

The International Fertilizer Association (IFA) elected seven new representatives to its Board of Directors at its Annual General Meeting, held in Singapore on 22 May. The AGM took place on the final day of the IFA Annual Conference 2024. The seven new Board Directors elected by the membership are: Bruce Bodine , Mosaic; Soufiyane El Kassi , OCP Nutricrops; Xiaofeng Hou , China BlueChemical; Dmitry Konyaev , Uralchem JSC; Jahangir Piracha , Fauji Fertilizer Company Ltd; Edward Weiner , Trammo, Inc.; and Kelvin Wickham , Ballance Agri-Nutrients.

In 1967, Stamicarbon revolutionised the urea production process with the invention of the HP CO₂ stripper by Mr Petrus JC Kaasenbrood. At a time when there was an energy crisis in many parts of the world, the HP CO₂ stripper led to three main benefits:

While there has been a lot of talk about decarbonising ammonia and methanol production, for as long as blue and green production is more expensive than conventional production, uptake will be dependent upon markets which are prepared to pay a premium for such chemicals, perhaps because they have no other reasonable choice, given environmental mandates. One sector above all has dominated the prospects for medium term demand for low carbon ammonia and methanol alike, and that is shipping.

Although global ammonia supply is set to increase this year, there is a shortage of new merchant capacity after 2024 which may lead to rising prices in the medium term.

Large-scale ammonia cracking technology and catalysts will enable the full potential of ammonia to be realised as industries transition towards low carbon energy. In this feature we report on the current status of ammonia cracking processes and catalysts.

BASF, SABIC, and Linde have jointly inaugurated the world’s first demonstration plant for large-scale electrically heated steam cracking furnaces at BASF’s Verbund site in Ludwigshafen, following three years of development, engineering, and construction work. The three companies signed a joint agreement to develop and electrically heated steam cracking furnaces in March 2021.
