Fluor investigates how SO2 impacts the Claus furnace temperature in an SRU and the ways to mitigate it. This article studies the extent of quenching experienced in the Claus furnace with varying amounts of SO2 in the Claus feed. A case study is presented based on real operating data of a refinery Claus plant with a feed gas cocktail that includes substantial SO2 recovered from a regenerative flue gas desulphurisation unit.
Sulphur dust is one of the greatest hazards when producing and handling solid sulphur, and methods for its suppression are vitally important to prevent fire and explosion.
In 2019 Topsoe launched its ClearView™ technology for WSA and SNOx sulphuric acid plants. This article focuses on the results and learnings from the first implementation of ClearView™ at a new WSA plant at Anglo American Platinum’s Polokwane smelter in South Africa.
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.
Gasification, particularly of waste and biomass, is seeing interest as sustainable sources of syngas. But there are both technical and commercial challenges to wider adoption.
Combining a deep scientific knowledge, engineering and field experience with state-of-the art technology, Johnson Matthey is proud to introduce its next generation of digital simulation tools via its JM-LEVO™ digital portals to further support customers in achieving their operational and sustainability targets.
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.
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.
