As the production of renewable methanol continues to scale up, it will provide a long term, carbon-neutral energy solution to different transport sectors. However, the optimum design parameters for green methanol plants are substantially different to natural gas-based methanol plants and pose new challenges to the methanol loop designer. Connor Longland of Johnson Matthey (JM) discusses the challenges and presents the benefits of the tube cooled converter for e-methanol production.

Lisa Krumpholz, Managing Director of Navigance, delves into the world of artificial intelligence (AI) and discusses its potential to enhance process optimisation in syngas plants.

KBR offers an end-to-end digitalisation solution specifically designed for green ammonia plants to balance the available renewable resources and consistently deliver the lowest levelised cost of green ammonia (LCOA). This article outlines some of the key modules of the KBR end-toend digitalisation solution developed to overcome the challenges in green ammonia operation and achieve best in class, safe and reliable plant operation.

Ammonia prices are expected to remain soft moving through January into February, with little in the way of price support from both a supply and demand perspective. January’s Tampa settlement was $100/t down on December at $525/t CFR.

Incitec Pivot says that Mauro Neves de Moraes has been appointed as Chief Executive Officer and Managing Director from 22 January 2024. De Moraes has leadership experience in the mining and logistics sectors including as Asset President for BHP Mitsubishi Alliance (BMA) in Queensland, Australia and Asset President at BHP’s Escondida operations in Chile, the world’s largest copper mine.

OCI Global says that it has reached an agreement for the sale of 100% of its interest in its large-scale nitrogen fertilizer subsidiary the Iowa Fertilizer Company LLC, located in Wever, Iowa, to Koch Ag & Energy Solutions for $3.6 billion. Completion of the transaction remains subject to US anti-trust approval and other customary closing conditions. The transaction is expected to close in 2024. Morgan Stanley & Co. International plc is serving as financial advisor to OCI on the transaction. IFCO produced 1.2 million t/a of urea ammonium nitrate (UAN) in 2021 and 700,000 t/a of anhydrous ammonia, as well as 700,000 t/a of diesel exhaust fluid (DEF).

In spite of nearly two years of western sanctions, Russian exports of nitrogen fertilizer have recovered almost to pre-war levels, while high prices led to record earnings in 2022.

Today some 75% of all urea plants worldwide operate a prilling tower as the solidification and finishing technology. A prilling tower is a large hollow concrete tower in which concentrated urea melt is sprayed from the top via a rotating bucket or static shower heads. The urea melt droplets cool and solidify while falling down some 70-100 m. The heat is removed by ambient air flowing upwards either as a natural draft due to the temperature increase or forced by means of air blowers.

Maire Group subsidiary MyRechemical has been awarded a feasibility study for the integration of its proprietary waste-tosyngas technology in a large-scale conversion plant that would transform solid municipal waste into 120,000 t/a of sustainable aviation fuel (SAF). MyRechemical would provide the gasification unit to transform solid waste streams into synthesis gas, which would then be converted into low carbon ethanol and then to SAF.

As Europe struggles to move away from its previous dependence on imported Russian natural gas, prices have been high and volatile, with a corresponding catastrophic impact upon domestic ammonia production.
