Stefano Cicchinelli and Carmen Perez of Stamicarbon (MAIRE) explore the latest advancements in tertiary abatement technologies, their implementation in nitric acid plants, and the implications for the fertilizer industry.
Part 1 of this series on stripper efficiency issues provided a brief history of the CO₂ stripping process and discussed how the invention of the HP CO₂ scrubber back in the 1960s revolutionised urea technology. In part 2 we take a look at how high liquid load can affect stripper efficiency.
The pursuit of operational excellence requires continuous process monitoring, together with qualified analysis of the collected data. The Digital Process Monitor (DPM) provides a process digital twin which consists of an accurate process plant model that incorporates the licensor’s knowledge and expertise in sulphur recovery technology, thereby providing continuous insights into plant performance. This article provides an overview of the DPM features focusing on the related benefits in terms of overall operational improvements and plant efficiency for the sulphur recovery unit.
Representatives from across the global sulphur and sour gas community convened in Abu Dhabi from 20 to 23 May to discuss and debate the key strategic themes that are driving the industry. The Middle East Sulphur Conference (MEScon) is a premier event that brings together representatives from the entire sour gas and sulphur value chain to promote technology and innovation, lessons learned, best practices, knowledge transfer and R&D.
As Comprimo celebrates its 100th anniversary, we explore the group’s history from its earliest days in the Netherlands in the 1920s to its current status as a global leader in gas treatment and sulphur recovery technology.
We highlight recent innovations, including fertilizers recovered from industrial residues, novel controlled-release coatings, and products that incorporate biological components designed to benefit both crop nutrition and soil heath.
The need for immediate climate action and cuts in carbon emissions has never been more urgent, especially in a world where ecosystems are increasingly under threat. The production of green fertilizers offers a clear route to achieving these goals by decreasing the chemical industry’s reliance on fossil fuels. Stamicarbon’s Carmen Perez, Rolf Postma and Nikolay Ketov outline the company’s innovative and integrated approach to green fertilizer technology.
RNZ Group is positioning itself as the most innovative and sustainable fertilizer producer in the UAE. In partnership with Shell, the company has been manufacturing sulphur-enhanced fertilizers using Thiogro technology since the end of 2022. Raza Soomar , RNZ’s managing director, provides an overview of the company and highlights recent business successes.
Elessent Clean Technologies introduces the MECS digital advisor, a web-based dashboard for plant performance assessment, troubleshooting and a supplemental mentoring tool for less experienced engineers and operators.
Large-scale ammonia cracking technology and catalysts will enable the full potential of ammonia to be realised as industries transition towards low carbon energy. In this feature we report on the current status of ammonia cracking processes and catalysts.
