VK Arora of KPI examines the technical and operational challenges of decarbonising legacy and new ammonia plants, drawing on a European case study of full-scale conversion supported by robust process and integration design. It also presents three US case studies exploring partial strategies, such as green hydrogen blending and oxygen enrichment, to reduce CO2 emissions and improve throughput. Together, these examples highlight a phased, cost-effective approach to decarbonisation, with blue hydrogen serving as a near-term transitional feedstock.

Casale is specialised in revamping natural gas-based methanol plants. Decarbonisation of methanol plants is a goal for many producers achievable with a proper revamping strategy. Pietro Moreo of Casale discusses how Casale’s innovative technologies and extensive experience ensure reliable efficient capacity and performance enhancements together with CO2 emissions reduction tailored to meet revamping project targets.

This article describes an unusual tube failure incident which resulted in fire escaping the furnace box during normal operation of a hydrogen plant. Ken Wohlgeschaffen of Chevron Products Company shares the sequence of events leading up to the incident, the extent of damage caused by the incident, and most importantly the causes and lessons learned from this incident to prevent recurrence.

The production of methanol from waste offers a groundbreaking solution for sustainable urban waste management as well as producing an alternative renewable fuel for maritime transport. Giacomo Rispoli, Andrea Angeletti and Alessia Borgogna of Nextchem provide an overview of the waste conversion process and its application.

No longer viewed as only a chemical feedstock, methanol is increasingly being regarded as a low-carbon energy carrier. Zinovia Skoufa of Johnson Matthey discusses the role of sustainable methanol as a multi-pathway fuel for the energy transition.

By combining oxygen-blown Lurgi™ autothermal reforming (ATR) technology with Cryocap™ H2 carbon capture technology, Air Liquide offers an innovative plant configuration to meet the need for a central production facility offering flexible product diversification with hydrogen and ammonia at a scale that satisfies extensive decarbonisation targets.

Green urea is urea based on green ammonia produced from renewable power via electrolysers and bio-based carbon dioxide and its colour is the same as normal urea. But in this round table discussion we discuss the possible causes for urea turning a green colour as found by the initiator of this discussion. We will learn that the colour of urea can be reddish or brownish in certain conditions where corrosion rates are high and/or oil fouling is high. But what can cause urea to turn green? n

Common risks of ammonia cracking as a new technology and how these risks can be recognised and mitigated by applying an innovative approach of the technology maturation process is described as seen through the eyes of an end user/investor. Addressing those risks is pivotal to enable end users to choose the best technology for their needs. Albert Lanser of Duiker Clean Technologies discusses some of these risks and how they have been addressed in its novel technology for producing the lowest levelised cost of hydrogen via its unique ammonia cracking process.

NextChem compares KPIs and overall costs to evaluate the performance of several low carbon (blue) hydrogen production technologies. A detailed comparison of SCT-CPO, SMR and ATR technologies is reported.

Muhammad Faisal Faraz and Abdullah Al Balushi of OQBi explain how by implementing a series of technical and process improvements, OQBi has successfully extended the lifespan of its reformer tubes by six years beyond the original design life of 100,000 hours.
