The Nigerian National Petroleum Corporation (NNPC) says that it plans to build a $3 billion methanol plant on Brass Island in the Niger Delta to produce up to 10,000 t/d of methanol using from gas supplied by Shell. A final investment decision was made by NNPC, DSV Engineering and the Nigerian Content Development and Monitoring Board, a state agency set up to ensure Nigerian involvement in oil and gas projects. Around 70% of funding for the project will come from international lenders, including the China Export-Import Bank, the African Development Bank and international commercial banks, with the rest funded from an equity issue. BP has signed a 10 year offtake deal for the plant’s output with the Brass Fertilizer & Petrochemical Company, the entity set up to operate the plant. Construction of the plant is expected to be completed by 2025.

From new materials of construction and improved equipment designs to the latest digital tools, Casale, thyssenkrupp Industrial Solutions, Saipem, TOYO and Stamicarbon report on some of their latest achievements.

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.

It can’t have escaped anyone’s notice that the question of the carbon intensity of ammonia and downstream nitrogen compound production has been one of the main industry talking points for the past year. Everyone seems to be talking about ammonia of different colours – green ammonia, blue ammonia, and all shades of turquoise in between. If you are confused, it may not be surprising, as these words have come to cover a wide variety of different methods and technologies for producing ammonia, and their green credentials consequently come in a whole range of different shades.

The year 2020 will be remembered as an uncertain, demanding and challenging year. When faced with a global pandemic, companies have adopted new approaches and remote inspection, monitoring and training using the latest digital tools has been key for the successful completion of projects. Stamicarbon, Casale and KBR share some of their experiences of the past year.

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.

NOx emissions from chemical processes such as steam methane reforming contribute to air pollution. The chemical industry is required to take steps to lower such emissions. Technology, developed for related industries, can be designed and optimised to reduce NOx emissions from steam methane reformers. Emission control experts can use a combination of modelling and experience to guide plant operators in recommending and designing optimum, sometimes tailor-made solutions. In this article different options are discussed including low NOx burners, selective catalytic reduction, selective non-catalytic reduction and high emissivity ceramic coatings.

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.

The following case studies describe serious incidents associated with leak detection system failures. Incident 4 relates to the failure of the active pressurised leak detection system for the loose liner of a urea reactor and Incident 5 relates to a passive leak detection system which failed to work leading to serious corrosion of the carbon steel wall of the HP scrubber.
