Experience, performance, reliability and support for mercury determination at petrochemical plants and refineries

Jan 09 2019 Read 123 Times

The presence of mercury (Hg) in petrochemical samples is very bad news. Even at ultra-low concentrations mercury is corrosive to gas plant components and infrastructure, poisonous to expensive downstream precious metal catalysts and exposes workers to highly toxic workplace conditions.

It’s no wonder that petrochemical plants and refineries spend vast sums every year removing even small concentrations of Hg from their precious gas and liquid sample streams. It is also no wonder that they wish to maximise the efficiency of their Hg removal systems and to achieve this, highly accurate and sensitive monitoring and measurement of Hg is required. Sub part per trillion sensitivities is the normally requirement.

For over 30 years PSA has been at the forefront of trace Hg determinations. PSA partners with many companies to monitor and help manage this Hg removal process. This partnership happens from the research bench through to production with PSA taking a pivotal role in ensuring successful removal technologies are deployed in the real world.

PSA have analysers to suit all aspects of the monitoring and analysis of Hg, including laboratory instruments and on-line analysers for gases and liquids. More recently PSA have provided solutions for speciation (fractionation) analysis and also waste water systems associated with petrochemical processes.

Employing atomic fluorescence spectroscopy as the means of detection the PSA analysers provide ultimate detection performance. With literally thousands of systems in the field today, and support networks in Europe, USA and SE Asia, PSA offers the ideal package of performance, reliability and support.
