Ammonia synthesis catalysts have seen major improvements over the last 100 years, and they are highly optimised with respect to activity, thermal stability, and poisoning resistance. Improving such catalysts even further requires a deep understanding of their structure and the impact of different parameters on performance. Clariant, Johnson Matthey and Topsoe report on their studies and developments in ammonia synthesis catalysts.
Casale has acquired Hong Kong-based Green Granulation Ltd (GGL), and its proprietary technologies for the design and construction of urea and calcium ammonium nitrate (CAN) granulation systems. Casale says that the takeover is part of a broader strategy aimed at strengthening its leading position in the nitrogen market by leveraging the widest integrated portfolio of efficient technologies, enabling the company to offer a ‘one stop shop’ for the entire production cycle of nitrogen-based fertilizers, from raw materials to final products. GGL’s addition to the Casale group includes the Cold Recycle Granulation process, an advanced fluidised bed technology designed to accept a lower concentration of urea feed melt (ca 96% urea and biuret), as well as a proprietary design for both granulator and scrubber, a team of experts and qualified technicians, and considerable experience in several industrial references. The CRG design has a horizontal layout, leading to lower structural costs and higher efficiency, as well as lower total investment costs and power consumption, lower power consumption and simplified operation, and higher operational flexibility in urea and CAN granulation.
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.
Late February saw the diplomatic crisis between Russia and Ukraine abruptly devolve into all-out war, on a scale not seen in Europe since the collapse of Yugoslavia in the early 1990s – some would argue not since the end of the Second World War. At time of writing, the conflict is still barely two weeks old, but has already produced an unfolding humanitarian catastrophe, and a refugee crisis of massive proportions. But over the medium and longer term, together with the international sanctions that have swiftly followed, it also has the power to deliver an economic shock to commodities markets in particular and the world economy in general that may be as bad if not worse than the crash of 2008-9.
Switzerland-based EuroChem Group AG says it has entered into exclusive negotiations to acquire the nitrogen business of the Borealis group, after having submitted a binding offer. One of Europe’s leading fertilizer producers, Borealis operates fertilizer plants in Germany, Austria and France, as well as more than 50 distribution points across Europe. It supplies 3.9 million tonnes of fertilizer products per year, including 800,000 t/a of technical nitrogen solutions and 150,000 t/a of melamine via the Borealis LAT distribution network. It is a market leader in melamine, with its operations in Austria and Germany supplying primarily the woodworking industry. EuroChem says that melamine and technical nitrogen solutions represent important new business lines for the company to expand its nitrogen-based product portfolio in Europe.
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.
The International Fertilizer Association (IFA) has signed a memorandum of understanding with the United Nations Food and Agriculture Organisation (FAO) over collaboration to support the FAO’s vision of transformative change and innovation in agriculture. Svein Tore Holsether, IFA Chair, signed the agreement at a live virtual signing in December together with FAO deputy director general Beth Bechdol. The agreement outlines collaboration to further shared goals and objectives with regard to the promotion of sustainable food and agriculture. Both parties will work together to raise awareness about the International Code of Conduct for the Sustainable Use and Management of Fertilizers (Fertilizer Code), promote education and knowledge transfer and continue their successful collaboration on fertilizer statistics.
More than 230 delegates from 45 countries participated in CRU’s Sustainable Fertilizer Production Technology Forum, 20-23 September 2021. To highlight this successful virtual event, we report on keynote and selected technical presentations.
Topsoe has begun operations at a demonstration plant for the production of methanol from biogas. The aim is to validate the company’s electrified technology for cost-competitive production of sustainable methanol from biogas as well as other products. The project is supported by the EUDP Energy Technology Development and Demonstration Program and is developed together with Aarhus University, Sintex A/S, Blue World Technology, Technical University of Denmark, Energinet A/S, Aalborg University, and Plan-Energi. The demonstration plant is located at Aarhus University’s research facility in Foulum, and will have an annual capacity of 7.9 t/a of CO 2 -neutral methanol from biogas and green power and is scheduled to be fully operational by the beginning of 2022. It uses Topsoe’s eSMR ™ technology, which is CO 2 -neutral when based on biogas as feedstock and green electricity for heating. It also uses half the CO 2 that makes up about 40% of biogas and typically is costly to separate and vent in production of grid quality biogas.
In China, requirements for methanol to produce olefins, mainly propylene and ethylene, from coal, has driven much of the growth in global methanol demand over the past decade. However, a new wave of ethylene cracker investment may put a stop to new MTO plant building.
