Particulate emission measurement in wet gas stream TUV-tested

Accurate particulate emission measurement in wet gas stream processes, such as monitoring after wet scrubber abatement systems and processes where the flue gas falls below the dew point or has water droplet presence can be challenging. The new PCME STACK 181 WS utilises an extractive approach with heating which overcomes the problem of interference from condensation and water droplets when using an in-situ particulate monitor after wet collectors.

Recently passing TUV testing against the QAL1 performance requirements, with a particulate monitoring certification range of 0-15 mg/m3 for wet gas streams marks a significant milestone.

The system uses an advanced ProScatterTM Light Scatter sensor (PCME QAL 181) which is certified by TUV and MCERTS as QAL1 compliant. With certification ranges covering both 0-15 mg/m3 and 0-100 mg/m3 dust levels and an operational range of 0-200 mg/m3, the sensor is suitable for monitoring the highly abated emissions found after Flue Gas Desulphurisation Plant (FGD). In addition, the instrument is able to monitor a saturated flue gas which is critical for the application of monitoring emissions from a coal fired power plant fitted with a wet FGD system and meets the requirements of
PS-11 and EN 14181.

Importantly, automatic zero and span checks on both the instrument and sample handling system are provided to ensure good quality measurements and to permit early diagnosis of any deterioration in system performance.

Easy and safe operator access to the measurement volume for external auditing with reference materials proves useful in satisfying AST linearity test requirements for
EN 14181 compliance and absolute correlation audit for PS-11 compliance.
