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.
EcoMax™ tail gas catalysts offer a sustainable and cost effective choice for tail gas catalysts. They are made from spent hydroprocessing catalysts, which reduces the environmental and socioeconomic impacts of sourcing fresh cobalt and molybdenum and therefore supports operators’ sustainability goals. B. Visioli of Porocel (a part of Evonik) discusses the benefits of catalyst reuse from hydroprocessing for tail gas treating.
Ammonia synthesis catalysts have long lives and catalyst replacement is an infrequent activity. Many people will go through their careers in the ammonia industry without ever having to replace a synthesis catalyst and the infrequent nature of catalyst replacement means that many plants may not have direct experience of this activity. Ammonia synthesis catalyst can present a range of hazards throughout the replacement process, from transport through loading, reduction, start-up, shutdown and discharge, but the good practice illustrated in this article, and collaboration between catalyst suppliers and end users can ensure safe and successful catalyst changeouts.
Because of the ongoing pandemic, this year’s CRU Nitrogen + Syngas conference was held as a ‘virtual’ event, in early March 2021.
Copenhagen Infrastructure Partners (CIP) has unveiled plans to build Europe’s largest power-to-ammonia facility at the Danish port of Esbjerg, based on electricity from offshore wind turbines. The company said the plant will consist of 1GW of electrolysis capacity, capable of supplying sufficient hydrogen to produce 300,000 t/a of ammonia, and that the ammonia will be used as both as agricultural fertiliser and as fuel for the shipping industry. Excess heat generated in the process would be used to provide heating for around one third of local households in communities around the plant, to be sited on the west coast of Denmark. The company has signed a memorandum of understanding for the project with companies from both the agriculture and shipping sectors, including Danish Crown, Arla, DLG, Maersk and DFDS Seaways. CIP anticipates that it would cost approximately $1.2 billion to build the facility. They are currently seeking investors for the project and expect that the investment decision would be reached by 2023. The plant could enter commercial operations in 2026.
Newly-developed froth flotation equipment and reagents are improving selectivity and the grade and recovery of phosphate concentrates.
Clariant, says that Conrad Keijzer become its new chief executive officer as of January 1st, 2021. Interim executive chairman Hariolf Kottmann has thus returned to his position as chairman of the board. Keijzer is a Dutch citizen with a long track record in the chemical industry, including 24 years with leading global paints and coatings manufacturer AkzoNobel, where he was CEO of the Performance Coatings Division and a member of the Executive Committee. Most recently, Conrad Keijzer was CEO of Imerys, a French supplier of mineral-based specialty solutions.
Johnson Matthey (JM) has secured a multiple licence for China’s Ningxia Baofeng Energy Group’s latest project to develop five of the largest single train methanol plants in the world. Located at Baofeng’s Ordos City complex in Inner Mongolia, the five plants each have a planned capacity 7,200 t/d. Under the agreement Johnson Matthey will be the licensor of all five plants and supplier of associated engineering, technical review, commissioning assistance, and catalyst. The plants will take synthesis gas as a feed and use JM radial steam raising converters in a patented series loop. Within the design, there is potential for 1-2% more feedstock efficiency over the life of the catalyst. Thanks to JM’s methanol loop synthesis technology, the plants will provide enhanced energy savings along with low OPEX, CAPEX and emissions. When complete, the plants will represent JM’s 13th operating license in China for a mega-scale plant (>5,500 t/d) and the fourth JM methanol design licensed by Ningxia Baofeng Energy.
This year the CRU Nitrogen + Syngas conference is going virtual. From 1 to 3 March 2021, the CRU virtual event will offer a live and on-demand agenda, interactive exhibition and enhanced networking capabilities on a platform tailored to make remote access as easy as possible.
Building on its long experience and leading position within global ammonia production, logistics and trade, Yara says that it aims to capture opportunities in green shipping, agriculture and industrial applications; a market expected to grow by 60% over the next two decades. A major first step includes plans to fully electrify its ammonia plant at Porsgrunn, Norway, with the potential to cut 800,000 t/a of CO 2 , equivalent to the emissions from 300,000 passenger cars.
