Aged sulphur products can be friable and fragile, which can lead to sulphur dust during handling. Because sulphur dust can lead to dust explosions and excessive wet sulphur contact corrosion, shipping and handling specifications for the safest products are used by producers, shippers and consumers to limit dangerous incidents. Metastable polymeric sulphur in the solid product limits friability and is rarely cited as a measured quantity within sulphur specifications, but often discussed when explaining best handling and forming practices. In this article, ASRL discusses why sulphur tends to be friable and explores several measurements cited in many specification documents, with the purpose of focusing on several modern solid forms. In addition, the measurement of total and extraneous water is explored.

Pejman Djavdan , CEO of Stamicarbon looks at the ways in which the fertilizer industry must grapple with issues such as decarbonisation, sustainability and more efficient use of nutrients.

Johnson Matthey (JM) has signed an LCH™ technology licence with Equinor and Linde Engineering for H2H Saltend, one of the UK’s largest low carbon hydrogen projects. JM was selected alongside EPC partner Linde Engineering for the major FEED contract by Equinor. The licence counts towards JM’s milestone of winning more than ten additional large-scale projects by 2023/24.

Further downward corrections are possible but the rate of demand is stabilising, suggesting the market floor is in sight, though some have suggested that May could bring another sharp reduction in the Tampa contract price towards the mid$300s c.fr. Demand remains sluggish in both eastern and western hemispheres.

Advances in clean hydrogen and ammonia production is fuelling worldwide interest in a new market for hydrogen and ammonia to provide a reliable low-carbon energy future. Ammonia cracking, the dissociation of ammonia back into hydrogen, delivers a pathway to large-scale sustainable hydrogen production. In this article KBR, Johnson Matthey, thyssenkrupp Uhde, Duiker, Proton Ventures and Casale report on their technologies and approaches to ammonia cracking in a low carbon economy.

With the market for green ammonia set to grow significantly in the coming years, modularisation of ammonia plants can bring many benefits to new projects, including optimised cost, speed of delivery and reducing overall risks. thyssenkrupp Uhde is committed to further develop standardised, modular solutions for its clients. Tobias Birwe and Dustin Mayor explain the company’s modularisation concept.

Pipe reactors in ammonium nitrate plants suffer from short lifetimes due to serious corrosion and erosion issues. A new solution from NobelClad could provide a unique opportunity to address the problem faced by licensors and end-users in the pipe reactors of ammonium nitrate plants. The NobelClad solution provides higher safety and reliability standards and less downtime and maintenance leading to an attractive payback time.

New methods for low-carbon ammonia production are emerging, while project activity is also rising rapidly.

Single superphosphate (SSP) is relatively easy and cheap to make. Yet traditional gas scrubbers often limit production and create plant maintenance issues.Fortunately, an innovative scrubbing technology developed by Armatec Environmental can overcome many of these problems. Based on high efficiency void towers, this new approach helps SSP producers meet stringent global emissions standards, explains Armatec’s Shane Pope , while simultaneously maximising production and improving worker conditions.

The production of renewable fuels by retrofitting existing refineries and their infrastructure is witnessing exponential growth. The impact on the existing amine, sour water and sulphur recovery units is inevitable. Based on several case studies, Marco van Son, Shashank Gujale and Tammy Chan of Worley Comprimo discuss the various options available to holistically review the sulphur block to determine the impact and mitigation of processing bio-feed.
