BASF has developed a new generation of promoter system compatible with MDEA solutions named OASE® yellow. The new promoter system increases the selectivity and capacity of the amine solvent, resulting in improved performance of tail gas treating units and allowing the processing of more sour crudes. A. Kern and G. Vorberg of BASF discuss two case studies demonstrating the benefits of OASE yellow.
When producing from shale reservoirs, technologies such as horizontal drilling and hydraulic fracturing have been used successfully to access hydrocarbons that otherwise could not be. A less publicised issue in producing from certain hot shale gas reservoirs (T > 100°C) is the presence of H2 S and organo-sulphur compounds in the production fluids. In trying to understand the non-biogenic sources of H2 S, Alberta Sulphur Research Ltd has been involved in studying the decomposition of chemicals used in hydraulic fracturing when exposed to high temperature and high pressure.R.A. Marriott, J.J. Marrugo-Hernandez and R. Prinsloo of ASRL discuss the findings of the study.
Haldor Topsoe has launched a new methanol synthesis catalyst, MK-181 PRIME, based on new technology developed via close study of copper-zinc interactions on the catalyst surface.
Imagine an industry that only uses carbon-free fuels and does not have any carbon footprint. Assume this is feasible within a decade. Now wouldn’t that be an ambition worth pursuing? Duiker believes this is achievable. A. Lanser provides Duiker’s view on how its SCO technology can act as an enhancer for reducing industrial carbon footprint.
As existing facilities grow older, service requirements increase. Equipment needs to be low maintenance and back in operation quickly after service and repair. Technology licensors are expanding their technical services with new digital tools, using digitalised expertise with real time insights and data driven analytics to boost chemical production and ensure that equipment operates reliably and efficiently, while maintaining product quality.
Paving the way for commercially attractive, sustainable, decarbonised fertilizer production, J. Dobrée of Stamicarbon BV discusses the latest developments for nitrate fertilizer production based on renewable feedstocks sourced from solar and wind energy. Stamicarbon has upgraded plant designs used in the past to create a new type of small-scale fertilizer plant capable of producing a product mix that can be adjusted to meet specific local requirements with maximised output value, thereby maintaining a competitive position towards imported products and large-scale producers.
Crystallisation, as a powerful separation technology and production process, is helping the fertilizer industry diversify its product mix, improve profitability and enhance sustainability, as Sana Boulabiar and Matias Navarro, of Veolia Water Technologies North America, explain.
Evaporation and crystallisation are widely used throughout the fertilizer industry. Major applications and the types of equipment used are reviewed by Laurent Palierne and Norbert Strieder of GEA Group.
Digitalisation and the analysis of big data are playing an increasing role in fertilizer production. Innovative digital and cloud-based services are being offered by a range of technology companies, including Casale, tkIS, Topsoe and TOYO.
We highlight recent innovations in sulphuric acid plant design and construction. NORAM and CPPE are offering a new hybrid sulphuric acid process. KVT, meanwhile, has upgraded its wet sulphuric acid technology to reduce capex, opex and emissions. Improved methods of construction and new materials from Koch Knight are also helping to optimise acid tower design
