In 1967 Stamicarbon revolutionised the urea process by the invention of the high-pressure CO 2 stripper by Petrus J. C. Kaasenbrood (pictured, left). The high-pressure CO 2 stripper led to following benefits:

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.

Worley has been awarded a contract to supply Chemetics’ CORESO2™ technology for a sulphuric acid plant and associated oxygen unit at the Arafura Rare Earths project, sited 135 km north of Alice Springs in Australia’s Northern Territory. A greenfield mine will extract and process neodymium and praseodymium to create ultra-strong permanent magnets for a range of applications, such as household electronics and high-performance motors for electric vehicles.

A reader wrote to me recently asking if I had considered the impact of general artificially intelligent systems like ChatGPT on the publishing industry. As a matter of fact I had, but only, somewhat narrowly and selfishly, on how it might impact my own job in the future. But the dramatic shift in AI capabilities that we have seen in the past couple of years is certainly food for thought, and I’ve seen no end of articles predicting the death of the creative industries.

New sulphur burning capacity in India is expected to come online in the coming months at fertilizer producer operations. This will lead to an increase in sulphur import demand but also impact sulphuric acid imports to the country.

BASF is challenging traditional catalyst shapes and performance relationships by introducing a radically new shaping concept resulting in materials with step change properties and performance. This innovative concept using 3D-printing technology is applicable to a wide range of reactions in the chemical industry and BASF is using sulphuric acid catalysts as the pilot to pioneer new ground.

Inshan S Mohammed of Sulfur Recovery Engineering shares the lessons learned from an emergency shutdown of an MCRC sulphur recovery unit in the middle of a cold Canadian winter where temperatures can be -30°C.
