Optical gas imaging technology, enhanced by artificial intelligence, offers a groundbreaking approach to monitoring SO2 emissions in real time. Andrés Russu of SENSIA introduces SENSIA’s RedLook solution which offers fully autonomous, 24/7 continuous monitoring of SO2 leaks, providing industries with the tools they need to maintain environmental integrity and operational safety.
Refinery sour water strippers are an often overlooked resource of low GWP ammonia. Martin A. Taylor and Charles L. Kimtantas of Bechtel Energy Technologies and Solutions, Inc. (BETS) show the results of a study on reusing an existing SWS as one of the major systems in a SWSPlus unit for the recovery of ammonia for sale. Relative cost factors will compare a complete SWSPlus unit versus reusing an existing SWS.
Join us at the CRU Sulphur + Sulphuric Acid 2024 Conference and Exhibition in Barcelona, 4-6 November, for a global gathering of the sulphur and sulphuric acid community. Meet leading market and technology experts and producers, network, share knowledge, and learn about market trends and the latest developments in operations, process technology and equipment.
Innovative catalyst systems from Heraeus and Łukasiewicz Research Network – New Chemical Syntheses Institute contribute to reach climate goals by reducing N2 O emissions during nitric acid production. Dr Uwe Jantsch and Jens Hesse of Heraeus Precious Metals report on the process performance results achieved for N2 O reduction in nitric acid production using FTC gauze systems and iron oxide based secondary catalysts.
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.
TOYO has recently introduced new proprietary urea technologies to its technology portfolio including a novel dust scrubbing system with integrated wet electrostatic precipitator (WESP) for ultimate clean-up of granulation or prilling exhaust air, to achieve urea dust emissions of less than 5 mg/Nm3 . Takuhiro Minato of Toyo Engineering Corporation explains how the new system works.
A plant operating a spent acid decomposition furnace as part of its sulphuric acid production facility desired to increase acid production primarily by processing additional spent acid while making minimal modifications to the plant equipment and operations. The Messer solution entailed introducing oxygen in two steps, both as an enrichment to the combustion air and by direct injection into the furnace. The resulting performance improvements exceeded the project objectives for acid production and spent acid decomposition, without increasing NOx emissions. This paper provides a summary of the system start-up and tuning and presents the resulting improvements and lessons learned.
While the events of the past few years have been difficult for Europe on many fronts, including a wholesale realignment of its energy sources with the restriction of access to Russian oil and gas, the effect on Europe’s sulphur production seems likely to be just as profound.
Sulphur plays an important role in crop nutrition. Indeed, sulphur is increasingly being recognised as the fourth major crop nutrient alongside N, P and K. However, a combination of intensive agricultural practices, increasing application of high-analysis fertilizers and tighter air quality regulations has led to increasing sulphur deficiency in soils. In this insight article, CRU’s Peter Harrisson looks at what’s driving sulphur deficiency and whether there’s a gap in the market for sulphur fertilizers.
To comply with environmental legislations, all new and most existing nitric acid plants must implement measures to reduce N2 O emissions to the atmosphere. This article explores the opportunities presented by Stamicarbon’s tertiary abatement technology for both existing and grassroots nitric acid plants to enhance sustainability and efficiency and discover the advantages of incorporating these technologies into a green fertilizer complex.
