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.
Rapidly escalating natural gas prices forced plant closures across Europe during September. Worst affected was the UK, where a fire at a cross-Channel electricity cable and low output from wind energy has, combined with low domestic storage capacity led to a surge in demand for gas for power stations and wholesale gas prices reached a record 350 pence per therm (equivalent to $46/ MMBtu) in October. On September 15th, CF Industries announced that it was halting operations at both its Billingham and Ince fertilizer plans due to high gas prices. Although ammonia prices have also risen, they have not kept pace with gas price rises, and there is a limit to what farmers could be expected to pay. CF CEO Anthony Will said: “$900 is the gas cost in a tonne of ammonia and the last trade in the ammonia market that was done was $700 a tonne”. As these plants supply most of the UK’s carbon dioxide for food and drink manufacture, the government said it would provide “limited financial support” to keep the Billingham plant operational, and that plant re-started on September 21st. Meanwhile, BASF closed its Antwerp and Ludwigshafen plants in Belgium and Germany due to what the company called “extremely challenging” economics. Fertiberia ceased production at its Palos de la Frontera site in Spain, and Puertellano remained down for scheduled maintenance. Yara shut 40% of its European ammonia production in September, and OCI partially closed its Geleen plant in the Netherlands. Achema in Lithuania decided against restarting its ammonia plant following maintenance in August, and OPZ in Ukraine shut one ammonia line at Odessa, with Ostchem and DniproAzot likely to follow. Borealis in Austria also reduced production.
China’s private sector Shenghong Petrochemical refining complex is targeting a startup in late November, following the receipt of its first cargo of crude in October. The greenfield refining complex in the eastern Lianyungang petrochemical zone has a capacity of 16 million t/a, including a 320,000 bbl/d crude unit – the largest single stream CDU in China – and a 76,000 bbl/d naphtha reformer. Product capacities include 56,000 bbl/d of gasoline, 41,000 bbl/d of diesel and 32,000 bbl/d of jet fuel. Construction began in mid-2019, delayed from 2018 by late approval of its environmental impact assessment, but has been achieved within two months of the scheduled completion date in spite of the coronavirus pandemic. Shenghong Petrochemical is owned by Eastern Shenghong, a producer of petrochemical products and chemical fibres.
Major fertilizer industry players such as Stamicarbon, Nutrien and CF Industries are ramping up investment in ‘green’ and ‘blue’ fertilizer production. Consequently, low-carbon production technologies are being scaled-up and deployed commercially.
BHP has finally given the go ahead for stage one of its Jansen potash mine project in Saskatchewan, Canada.
OCI subsidiary Fertiglobe says that it has partnered with the Abu Dhabi National Oil Company (ADNOC), to enable the sale by ADNOC of the first cargo of blue ammonia to Itochu in Japan, for use in fertilizer production. Fertiglobe, a 58% − 42% partnership between OCI and ADNOC respectively, will produce the blue ammonia at its Fertil plant at Ruwais in Abu Dhabi for delivery to ADNOC’s customers in Japan. This represent the first production milestone of a planned scale-up of blue ammonia production capabilities in Abu Dhabi, which is expected to include a low-cost debottlenecking program at Fertil. In addition, it was announced in June that Fertiglobe will join ADNOC and sovereign wealth fund ADQ as a partner in a new world-scale 1.0 million t/a blue ammonia project at Ta’Ziz in Ruwais, subject to regulatory approvals. The design contract for this project has been awarded, with a final investment decision expected in 2022 and start-up targeted for 2025. A feasibility study was also agreed in July betweenh the state-owned Japan Oil, Gas and Metals National Corp. (Jogmec), Inpex and JERA as well as ADNOC to explore the possibility of producing 1.0 million t/a of blue ammonia in Abu Dhabi and transporting it to Japan.
Although the stranded gas boom that led to the construction of the region’s nitrogen capacity in the 1980s-2000s may be largely over, the Middle East remains the largest nitrogen exporting region in the world.
