Due to ever stricter legislation towards lower SO2 emissions, superior catalyst shape and composition has become ever more important. Jochen Willersinn of BASF SE explains how BASF’s high-performance catalyst O4-116 Quattro combines the benefits of an increased surface area with a superior caesium-promoted active phase composition enabling significantly lower ignition and operating temperatures and thus reducing SO2 emissions.

This study introduces a new platinum-promoted honeycomb catalyst for sulphur dioxide oxidation, designed to enhance energy efficiency and reduce emissions in sulphuric acid production. Compared to conventional vanadium oxide based catalysts, the platinum-based catalyst demonstrates higher catalytic activity, lower ignition temperature, and significantly reduced toxicity.

Johnson Matthey technology selected for one of the largest planned e-methanol plants in Europe Reolum project represents the fifth win contributing to JM’s strategic milestone of 20 sustainable technologies project wins by the end of 2025/26 JM has won 15 major energy transition projects since 1st April 2022 Sustainable energy project to operate in region […]

India’s phosphate production is using increasing volumes of sulphuric acid, but new domestic smelter and sulphur burning acid capacity may mean reduced imports in future.

NextChem has been awarded two contracts to upgrade and expand the capacity of the Heydar Aliyev Oil Refinery (HAOR) industrial complex in Baku by state oil company SOCAR. As part of the contract, NextChem will conduct a technological assessment and deliver a process design package to upgrade the existing sulphur recovery unit (SRU) with oxygen enriched air, a cost-effective and flexible solution for expanding its current sulphur production capacity. Additionally, NextChem will provide the licensing and the process design package based on its proprietary NX SulphuRec TM technology for a new SRU. NX SulphuRec TM is a portfolio of proprietary sulphur recovery technologies, based on the integration of modified Claus and tail gas treatment processes, aimed at reducing the environmental impact of acid and sour gases produced during the refining process.

The development and implementation of modern process instruments and control systems in sulphur recovery units has increased significantly over the last decade. In this article, the impact of BTEX on sulphur plant operations and how the BTEX concentrations can be measured are discussed.

Marcus Weber of Fluor discusses degassing units for large scale sulphur recovery units, evaluating the pros and cons of various available commercial technologies with the emphasis on mega size sulphur recovery units and focussing on how technology can lower degassing capex via economy of scale for new facilities or existing facilities undergoing expansion.

CRU’s 38th Nitrogen+Syngas Expoconference will be held on 10-12 February 2025 in Barcelona. The most respected technical event for the global nitrogen and syngas community offers an ideal platform for industry professionals to connect, do business and learn about the latest innovations in operations, technology, process and equipment. The annual meeting attracts a global audience of producers, licensors and materials and equipment providers representing an unparalleled opportunity for business networking and peer-to-peer knowledge sharing.

In Part 3 of this series on stripper efficiency issues, we continue the discussion on some some of the many causes of lower stripper efficiency. Here we discuss liquid divider fouling and bad installation of liquid dividers.
