Sulphur recovery units in petroleum refineries and natural gas processing plants utilise incineration as a final treatment step for tail gas, ensuring that residual sulphur compounds are converted to less harmful emissions. Elmo Nasato of Nasato Consulting Ltd compares the two sulphur plant incinerator options – thermal incineration and catalytic incineration – including key considerations for policymakers, businesses, and environmental advocates.
Efficient sulphur recovery is essential for modern refineries to meet stringent environmental regulations and support sustainability goals. Fluor examines the key design considerations, smart design strategies and flexible sulphur block configurations that are essential in achieving an overall optimised design. Together, these strategies enhance efficiency, reduce emissions, improve reliability, and provide flexibility for changing crude qualities, ensuring compliant and economically robust refinery operations.
Worley Comprimo has carried out an evaluation of technologies allowing 99.8+% sulphur recovery for an Indian refinery case. The TopClaus process was compared to alternative technologies, focussing on modern technical challenges, investment operation and maintenance costs, as well as CO2 considerations.
Diaphragm seals are applied when pressure or level transmitters need to be protected against harsh conditions like the corrosive ammonium carbamate in urea plants. The process pressure is transmitted via the flexible diaphragm and transmission fluid to the measuring instrument as shown in Fig. 1 below.
NX eBlue™ is a next-generation hydrogen production technology, ready for industrial deployment, that integrates electrification with renewable energy to deliver a low-carbon, high-efficiency alternative to traditional steam methane reforming. M. Antonelli, M. Mennella, and Dr. S. Romagnuolo of KT Tech S.p.A. describe NEXTCHEM’s proposal for the electrification of steam methane reforming.
Toyo Engineering Corporation (TOYO) has developed two proprietary technologies – g-Methanol ™ and SUPERHIDIC ™ – to enable ultra-low carbon e-methanol production.
As demand for green methanol grows, the Kassø e-methanol plant in Aabenaa, Denmark represents a significant milestone as the first commercial-scale e-methanol production facility in operation with a nameplate capacity of 42,000 t/a. European Energy and Clariant describe the technical collaboration between them in executing this pioneering e-methanol project
The selection of the post-combustion carbon capture technology to be implemented for a decarbonisation project is a crucial element during the early feasibility phases and it is strongly affected by the characteristics of the plant on which it has to be installed. NextChem highlights the comparative advantages of absorption technologies and the alternative opportunities of using a cryogenic configuration to reach the desired carbon capture rate.
In this study Kinetics Process Improvements (KPI) demonstrates that controlled ethane co-feeding combined with intermediate methanol condensation in the synthesis loop provides a practical, low capital, low-risk revamp strategy to increase ATR methanol plant capacity by approximately 5% while remaining fully within existing equipment, metallurgical, and compression limits.
Clariant demonstrates how ammonia plant performance can be maximised through advanced low temperature shift solutions. Clariant’s combination of ShiftMax 217 Plus and CLARITY Prime delivers benefits that neither superior catalysts nor digital tools could achieve alone.
