A cleaner future for us all Gas analysis is essential to creating cleaner plant and refin - ery operations. It also supports emerging trends in the industry, such as the desire for greater process optimisa- tion, the move towards cleaner fuels, and the achievement of higher product yields. This wide range of objectives requires an equally wide range of sensing technologies, so partnering with an expert gas analysis supplier offering a diverse selection of technol- ogies is vital to ensure the best fit and most cost-effective solution for each application. When developing partnerships with suppliers of gas analysers and other key systems, it is also important to look at the sustainability of those organisations to ensure they have a demonstrable and measurable commitment to oper- ating responsibly. Service support is another key consideration in maintain- ing gas analysis systems at peak performance to ensure plant operations remain as clean as possible. By combining all these elements into a coherent, con- nected clean air strategy supported by accurate and reli- able gas analysis, plants and refineries can fully address the impact of their operations on the environment, helping to create a better, cleaner world.
performance while minimising pressure drop. More pre- cisely, it incorporates a large and uniform open area in every direction and under any orientation, maximising surface exposure to liquid and vapour while reducing the likelihood of dry zones. The only random packing types in PEEK available on the market before NeXRing were obsolete second-generation rings, forcing users to compromise, as they had to choose between performance or resistance. Therefore, replacing older-generation random packings made of metal or other materials with the latest NeXRing can lead to considerable enhancements in productivity, efficiency, and through - put. VICTREX PEEK material was selected after extensive testing as it proved to offer the best properties for many applications. Even more, compared to earlier random packing gen- erations, the new solution can support the use of smaller columns while offering higher capacity and the same or improved separation performance. This can further reduce capital expenditure in new units or, when retrofitting exist - ing columns, increase throughput and yield.

ExxonMobil launches world’s largest low-carbon hydrogen project
Sulzer Chemtech’s advanced thermoplastic polymer supports processing of harsh chemicals The proprietary NeXRing in VICTREX PEEK polymer from Sulzer Chemtech is ideal for supporting the processing of harsh chemicals, thanks to its high temperature (up to 250°C) and chemical resistance. In effect, PEEK (poly ether ketone) is a thermoplastic and is versatile. It is designed to meet the need for component reliability and efficiency in challenging environments. Providing enhanced support for key processes, typi- cal NeXRing applications include separations that involve caustic soda, sulphur dioxide, phosphoric acid, halogenated organic compounds, chlorosilanes, acetic acid, seawater and, when concentrations are less than 10%, nitric and hydrochloric acids. Therefore, the technology can benefit companies in a variety of sectors, from chemical and petro- chemical to refining industries. By utilising this random packing product in new or exist- ing columns, companies can benefit from considerable cost savings, as it is possible to operate at optimum conditions while reducing the frequency of maintenance activities and their associated expenses. In addition, PEEK-based compo- nents tend to be more economical than exotic alloys, lower- ing the initial investment. The use of an advanced thermoplastic polymer also improves the mechanical strength, wear resistance, and separation performance of NeXRing. This fourth-genera- tion random packing was developed to optimise hydrau- lic performance, maximising capacity and separation
An ExxonMobil facility deploying the largest low-carbon hydrogen project in the world will incorporate Honeywell technology to enable capture and storage of carbon dioxide. ExxonMobil plans to deploy one of Honeywell’s carbon capture technologies, the CO₂ Fractionation System, at its facility in Baytown, Texas, the second largest refinery in the US (based on production). The technology will be integrated into the design of ExxonMobil’s new hydrogen production assets and enable the capture of about 7 million tons of CO₂ per year at the facility – the equivalent of the emissions of 1.5 million cars for one year.¹ The technologies that make up the CO₂ Fractionation System could allow ExxonMobil’s Baytown facility to cap- ture more than 98% of associated CO₂ emitted from the hydrogen plant and deliver low-carbon-intensity hydro- gen.² The CO₂ captured in this process will then be seques - tered in underground storage by ExxonMobil. The facility is expected to produce around one billion cubic feet of low-carbon hydrogen per day. ExxonMobil’s Baytown inte- grated complex is home to the largest olefins plant in the US. The site is located on approximately 3,400 acres along the Houston Ship Channel. According to ExxonMobil, the low-carbon hydrogen, ammonia, and carbon capture facility is expected to be the largest low-carbon hydrogen project in the world, with a planned start-up in 2027-2028. Carbon capture, utilisation and storage (CCUS) technologies are designed to capture CO₂ from the atmosphere or a source, such as an industrial
