MCERTS approval for Rosemount gas analysers

Emerson has gained UK MCERTS approval for the Rosemount Analytical range of gas analysers for continuous emissions monitoring systems to monitor for NOX, SO2, CO and O2, plus VOCs and hydrocarbons

Emerson Process Management has gained UK MCERTS approval for its Rosemount Analytical range of gas analysers for continuous emissions monitoring systems (CEMs).

The approval covers the MLT 1, MLT 2, MLT 3/4, TFID and CLD analysers, which have been tested and found to comply with the UK Environment Agency performance standards for emission monitoring.

In order to be granted MCERTS approval, analysers are performance tested in the laboratory, and are monitored on-line under real-world application and environmental conditions while installed in large combustion (power generation) and incineration plants.

Factors such as accuracy, repeatability, linearity and long term stability are monitored over an extended period.

These Rosemount analysers already comply with the exacting German TUV standard and, with the added benefit of UK MCERTS approval, the range now complies with the two most respected standards, recognised and accepted across Europe.

The approval covers the MLT series of NGA 2000 analysers, which offer multi-component, multi-method analysis using non-dispersive infrared (NIR), ultraviolet (NDUV) thermal conductivity, paramagnetic and electrochemical sensor technologies.

This Rosemount Analytical MLT series is used to measure the concentrations of NOx (NO and NO2), CO, SO2 and O2.

Also approved are the Rosemount Analytical TFID (Thermo Flame Ionisation Detector) and NGA 2000 CLD (Chemiluminescence Detector) analysers, which extend the emissions measurement capability to include measurement of volatile organic carbon (VOCs)/ total hydrocarbon (CH) and lower levels of NOx (NO/ NOx).

Rosemount Analytical gas analysers have proven world-wide performance in process gas analysis, emissions monitoring from internal combustion engines for engine development, and stack gas monitoring for industries that include gas, chemical and metallurgical, process power generation and waste incineration.

The UK Environment Agency promotes the use of Continuous Emission Monitoring Systems (CEMS) by industrial operators for compliance monitoring purposes.

To support this scheme, Her Majesty's Inspectorate of Pollution (HMIP), GAMBICA (The Association for the Instrumentation, Control and Automation Industry) and the DTI/DoE Joint Environmental Markets Unit (JEMU) funded a collaborative initiative to establish the basis for a UK certification service for CEMS and this is operated in the UK by SIRA, an independent testing laboratory.

The MCERTS Scheme is formally recognised in the UK and accepted internationally.

It provides instrument manufacturers with an independent authoritative endorsement of the practical performance of individual products.
