The curtailment of ammonia production in Europe and reduction in export supply from Russia has led to an unprecedented year for the merchant ammonia market.

The latest improvements to melamine process technology now make it even easier to integrate a melamine plant with an ammonia and urea fertilizer complex. Guido Canti of Eurotecnica and Marc Wieschalla of thyssenkrupp Uhde discuss the benefits of plant integration.

Topsoe has made a number of changes to its board. Kim Saaby Hedegaard has been appointed as the company’s new Executive Vice President, Power-to-X. Hedegaard has served as interim Head of Power-to-X since May 2022. Before that, he held the position as Chief Operations Officer (COO). He joined Topsoe in 1999 and has since held various leadership positions within engineering, technology, and sales. Since 2017, he was responsible for Catalyst Production and Technology globally. He holds a MSc in chemical engineering from the Technical University of Denmark. He is replaced as COO by Andreas Bruun Jørgensen.

Industry focus on technologies to reduce the carbon intensity of ammonia and methanol production has been intensifying. In this article thyssenkrupp Uhde, Proton Ventures, Toyo Engineering Corporation, Stamicarbon, BD Energy Systems and KBR report on some of their latest technology developments towards decarbonisation.

Refractories are heat resistant materials used in high temperature processes to protect industrial equipment such as utility boilers, heaters, and ammonia primary and secondary reformers against heat and chemical attack. In this article Hasan Akbari of Kermanshah petrochemical Industrial company (KPIC) reports on experiences of different stages of refractory casting in the secondary reformer of an ammonia plant, located in Kermanshah province of Iran (KPIC – Phase II). The pouring operation was carried out in three stages and each section was cast nonstop for a period of three days in total.

Fischer-Tropsch technology has long offered alternative production routes to synthetic fuels, but has struggled to make a use case outside of some niche applications. Could the greening of the chemical industry offer another way forward for the technology?

Venkat Pattabathula, a member of the AIChE Ammonia Safety Committee, reports on the American Institute of Chemical Engineers’ Safety in Ammonia Plants and Related Facilities Symposium, held at the Hyatt Regency in Chicago, USA, on 11-15 September 2022.

Catalysts are of crucial importance in a number of chemical processes and hence, their quality has a direct impact on the efficiency and operating costs of chemical plants. This refers especially to ammonia production, since this process is energy-consuming.

Seshu Dharmavaram of Air Products and Venkat Pattabathula of SVP Chemical Plant Services describe the Dakar ammonia accident, which occurred in Senegal on March 24th, 1992. It is claimed to be the worst industrial ammonia accident ever, leaving 129 dead and 1,150 injured.

Maersk has ordered six more 17,000 teu (twenty-foot equivalent unit) container ships capable of running on methanol from Hyundai Heavy Industries (HHI). The order brings Maersk’s total order book of dual-fuel vessels capable of running on methanol to 19. Maersk said the new ships will replace existing tonnage in its fleet when they’re delivered in 2025. When all 19 vessels on order join the fleet and replace older tonnage, CO2 savings will be around 2.3 million t/a, according to Maersk. Maersk has committed itself to renewable methanol as a pathway to zero emissions shipping. Its first vessels are due for delivery from Q1 2024. The company has also signed several green methanol fuel supply agreements and joined a partnership to create the first e-methanol plant in Southeast Asia. Maersk is also working with Japanese trading house Mitsui and the American Bureau of Shipping (ABS), to jointly conduct a detailed feasibility study of methanol bunkering logistics in Singapore.
