    Product Description

    The measurement of SO3 within an industrial plant process can be challenged by various factors, including the type of fuel, process conditions (moisture, temperature, particulate levels) and the presence of pollution control devices such as SCRs, ACI systems and FGD scrubbers. Yet accurately monitoring SO3 levels is critical to controlling process parameters that can provide cost savings, extend the life of process equipment and reduce the risks of the “blue plume” effect outside the stack. The Arke SO3 System provides true continuous SO3 monitoring capabilities with relatively fast response times, which can assist in optimizing your sorbent usage. Utilizing an advanced QC Laser-based platform, the Arke SO3 System maximizes the sensitivity and selectivity of SO3 measurement. The Arke SO3 System comprises of the Thermo Scientific 9800 SO3 Analyzer and the Thermo Scientific PRO9805 Dilution Extractive Probe.
