When process or emission gas measurements are required from a fixed point or range of sample points, Protea can supply a bespoke fixed measurement system. At the heart of all ProtIR 204C gas monitoring systems is the 204M gas analyser, surrounding which is a configurable set of automation and control systems to allow Continuous Emissions Monitoring (CEM). Each 204C system is uniquely designed to apply the FTIR technology, dependent on the monitoring needs of the application.
As the systems are built around the MCERTS approved ProtIR 204M, guarantees of instrument accuracy and robustness are met. The 204M base provides heated gas cell, pressure sensor, dilution control, optional oxygen sensor and nitrogen purge. The 204M can be removed from the 204C enclosure for maintenance, but also if needed to be set-up for mobile emissions monitoring.
Each final 204C configuration is then built up to provide a bespoke solution relevant to the continuous monitoring application. This can include heated sample line, multi-stream selection valves, multiple I/O, flow measurement and control and many other additions to complete the system.
The ProtIR 204C analysers are designed to be run with Protea Analyser Software for Process (PAS-Pro). This software allows for the continuous collection, labelling and storing of spectral data and concentrations from the FTIR. It also allows complete management of the sampling system, running automated routines and handling any alarm scenarios.
PAS-Pro is based around components of the standard PAS software package. PAS is used to build analyser configurations and analysis routines, which can then be uploaded to PAS-Pro on 204C systems. Data collected can be opened back in PAS for advanced analysis offline.
A single fixed FTIR gas analyser can be used to measure from many different sampling points with a bespoke multi-point sampling system from Protea. Whether an automated or manual stream selection, Protea can deliver a sampling system that keeps the sample stream well-conditioned before passing to the analyser.
Automated multi-point sampling system controls can keep dozens of heated lines, heated probes and heated valve switches at the required temperatures. Stream selection can be automated to allow sequential measurement from multiple streams.
