Hazardous area certifications for wall mountable analysers


Hazardous area certifications for wall mountable analysers

AMETEK says that its 993X series of analysers, encompassing the 993X and 9933, are now ATEX and IECEx Zones 1 and 2, and ETL (North America) Class I Division 2 compliant for use in hazardous locations with ambient temperature up to +60ºC. Built with IP66-rated enclosures, the 993X analysers can be installed outdoors, or in minimally temperature-controlled enclosures, reducing both capital and operating costs.

The 993X series of analysers use ultraviolet spectroscopy to measure hydrogen sulphide, carbonyl sulphide, and methyl mercaptan in natural gas and biomethane gas streams. These analysers are also used to measure hydrogen sulphide, carbonyl sulphide, carbon disulfide, sulphur dioxide, and hydrogen in sulphur removal and recovery operations.

Michael Gaura, senior product manager explained, “Due to increasing demand from our customers and with the need to deliver an analyser that meets strict safety standards, we have continued to extend the capabilities of our highly successful 993X analysers. Using an integrated cooling system to maintain internal temperatures of the enclosure, the 993X analysers are designed to operate in higher ambient temperatures and locations where explosive atmospheres may occur, making the analysers compliant to ATEX & IECEx Zone 1 & Zone 2, as well as Class I and Division 2 locations.”

Challenges in the conversion to clean ammonia

VK Arora of KPI examines the technical and operational challenges of decarbonising legacy and new ammonia plants, drawing on a European case study of full-scale conversion supported by robust process and integration design. It also presents three US case studies exploring partial strategies, such as green hydrogen blending and oxygen enrichment, to reduce CO2 emissions and improve throughput. Together, these examples highlight a phased, cost-effective approach to decarbonisation, with blue hydrogen serving as a near-term transitional feedstock.

Axens expands TGT catalyst production

Axens says that it has completed the expansion of its Axens Catalyst Arabia Ltd site, aimed at providing local and regional partners with the latest tail gas treatment catalysts, in addition to the site’s legacy catalyst hydroprocessing manufacturing capacity. This makes Axens is the first and only company to produce tail gas treatment catalysts in the Middle East. The company says that the expansion consolidates its capacity to serve its regional customers to meet regulatory requirements and maximise sulphur recovery by up to 99.9%, minimising SOx emissions. The production site supplies the region’s refining and gas industries with the latest generation of Axens’ catalysts, capable of operating at lower temperatures than conventional catalysts, and resulting in lower energy consumption.
