In-Situ CEMs

In-situ Continuous Emissions Monitoring (CEM) analysers are flange mounted to the emissions point, with an in-situ sample cell inserted into the stack. Installing an in-stack CEM analyser removes the need for costly and high-maintenance sample handling components. Protea offers both Infra-Red (IR) and Ultra Violet (UV) in-situ gas analysers.

The in-situ CEM systems are multi-component and can monitor multiple gases species simultaneously. The analyser also monitors water vapour and so the pollutant gases can be reported on a wet or dry bases depending on the local environmental agencies requirements.

The Protea In-Situ Analyser incorporates an automatic zero and calibration gas unit and is controlled by the microprocessor in the analyser.

This allows the periodic zero and calibration to be carried out, fully challenging the system.

The stack mounted analysers can accept up to five analogue inputs from third party instruments such as Oxygen, Velocity and Particulate. This gives the system the capability to report pollutant concentrations normalised and in mass units such as kg/hr.

The stack mounted analyser is connected via a serial link to the analyser control unit, which displays, data logs and re-transmits the concentrations (ppm, mg/Nm3, %) of the monitored flue gas components. Up to eight (8) analysers can be connected to a single Protea Analyser Control Unit.

Certification with environmental monitoring equipment standards is dependent on analyser series and application. Certification of models includes EN 15267-3 MCERTS; EN 14181 QAL 1 and US EPA 40cfr part 60 & 75.

Comparison Continuous Emission Monitoring Techniques

Protea 2000 In-Situ Infra-red gas analyser connected to a Protea Control Unit forms the basis of a Continuous Emission Monitoring System (CEMS). The Stack Mounted In-Situ analyser monitors the stack gas without the need for any sample handling equipment making it a cost effective solution to Continuous Emission Monitoring and Process applications. The analyser monitors the stack gases “wet”, water vapour is continuously monitored enabling the pollutant gases can be reported on a wet or dry basis.

Data Sheet

MCERTS Product Conformity Certificate

Protea 5000 is an ultra-violet (UV), continuous emission monitoring analyser, designed for in-situ analysis of gas-phase emission components. Using absorption spectroscopy, Protea 5000 stores and analyses the full UV spectrum and calculates the gas emission concentrations.

Data Sheet

In addition to collecting data from Protea’s P2000 and P5000 analysers, it is configured to receive data from complementary devices, e.g. Dust / Opacity, Oxygen and Flow. This enables the system to display gas concentrations on a normalised basis and, if required, in mass units e.g. Kg/hour. The analyser communicates via a serial data link to the control unit, which can be located up to 1200m from the CEMS. Intuitive software is designed to utilise either a pointing device or touch screen for all operator functions. The Protea S-PC is capable of supporting up to six Protea Analysers with associated third party devices.
