As a quick glance through the Index of last year’s articles and news items in this issue of the magazine will amply demonstrate, 2021 was a year full of project announcements for low carbon ammonia and methanol projects of all hues; blue, green, turquoise and many other shades besides. Market analysts CRU said in December that they calculated that there have been a total of 124 million t/a of low carbon ammonia projects announced, 80 million t/a of which came in 2021 alone, equivalent to 55% of current ammonia capacity. These range from tentative pilot plants that are fully costed and often with government grants already secured to blue sky visions of vast electrolysis hubs in the deserts of Arabia with timescales towards the end of the decade – it’s often the case that the longer the proposed timescale, the less likely a project is to happen.

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.

The Bia Energy Operating Company says that it is evaluating a $550 million blue methanol plant at the port of Caddo-Bossier in Shreveport, Louisiana. The unit would have a capacity of 530,000 t/a of methanol using natural gas feedstock with downstream carbon capture, reducing CO2 emissions by more than 90% compared to other methanol plants. The company is expected to make a final decision in 1Q 2022, with construction expected to last approximately two years, and commercial operations to begin soon after.

Last year the International Energy Agency (IEA), in conjunction with IFA, published the Ammonia Technology Roadmap, which looks at ways of achieving decarbonisation of the nitrogen fertilizer industry by 2050. In this article we look at the scenarios and technology options that will define the industry over the next three decades.

As the world looks to a lower carbon future, refineries are having to examine their operating models, and look to, for example, renewable hydrogen production for desulphurisation technologies.

Global demand for oil products has seen strong recovery in 2021, but depressed kerosene demand from the aviation sector continues to be a major barrier to full recovery, according to data and analytics company GlobalData. The company’s analysis of oil product flows suggests that when kerosene is excluded, oil product demand in Q3 2021 had fully recovered compared to the same period in 2019. However, demand for kerosene, mostly used for jet fuel, has hovered at around two thirds of pre-Covid-19 levels throughout the year, and when that is taken into account, total oil product demand was 3% below pre-Covid levels for Q3 2021. Kerosene demand saw the greatest impact from Covid-19 due to restrictions on air travel. While the sector recovered, to an extent, in the second half of 2020, recovery stalled in 2021 due to new waves of infections and restrictions, with new restrictions linked to the Omicron variant likely to have hit demand again in Q4.

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.

Reducing carbon footprint in the synthesis of chemicals is a new challenge, a necessary requirement in the pursuit of sustainable products designed to minimise environmental impacts during their whole lifecycle. So-called “green” technologies for ammonia, methanol and hydrogen are being developed to meet these challenges. Casale, Linde, thyssenkrupp Industrial Solutions, Toyo Engineering Corporation, Haldor Topsoe and Stamicarbon report on some of their latest developments.

A detailed rain and wastewater concept is an important part of a urea plant to meet current stringent environmental standards. Wastewater can originate from the process reaction or from outside the process equipment. In order to optimise the wastewater system of a urea plant, both the amount and type of contamination need to be known. With this knowledge, non-contaminated rainwater as well as process drains can be kept separate as much as possible to minimise the amount of wastewater to be treated, saving costs and energy. Wastewater treatment concepts from thyssenkrupp Industrial Solutions and Toyo Engineering Corporation are described.
