SmartCEMS® Proprietary gas path/cell

Our rental SmartCEMS® is fitted with 10.6 v PID. A unique feature is to allocate a gas channel to sensible sensors. Its design ensures the cells have a limited exposure to gases and therefore extends considerably their respective life-time.

Optimised integration
Our rental SmartCEMS® is a compact system delivered ready for installation. Thanks to its small size, the system is easy to locate, install and set-up. The routing of the cables and tubes to the instrument is simplified with all gas and electrical connections grouped onto a single interface plate.
Versatile
The SmartCEMS® sampling system configuration can be adapted to specific monitoring needs such as multipoint monitoring, redundancy, continuous or time set measuring cycles… When sampling from wet and hot gas, moisture content, condensates and salts are continuously removed by the use of one or several gas dryer(s) (Peltier or Nafion) equipped with built-in safety filter, condensate trap and safety inline particulate filters. Whether the SmartCEMS® uses the built-in sampling pump or the pressure from the source, the analyser is designed to work with overpressure. Single gas channel configuration can handle overpressure up 1.8 bar.
Pleasant interface
The SmartCEMS® powerful and pleasant PC interface provides operators and system integrators with a broad range of settings to adjust many aspects of the measurement tasks such as automated sampling, calibration, purge sequences, analogue outputs behaviour, data presentations… For large sites with complex monitoring requirements, the LAN and ModBus interfaces allow implementing in an efficient way large instruments networks with master/slave configurations and user settable monitoring functions.

SmartCEMS® Sampling System

Stationary Gas Sampling Probe

The SmartCEMS® stationary gas sampling probe has a modular design to fit most of CEMS and Process applications. The Probe configuration can be adapted to the sampling conditions and environment (gas temperature, dust load…). The SmartCEMS® stationary Gas sampling probe features insitu sintered stainless steel filter, Gas temperature measurement with K-type thermocouple, backflush valve (manual or automatic)to blowback the filter. The SmartCEMS® stationary gas sampling probe is typically flange mounted directly onto the sampling duct. Once extracted the sample is then directed to the gas conditioning system through heated or unheated sampling line.

MD3 Gas Conditioning Unit

The SmartCEMS® MD3 Gas Conditioning unit is equipped with a condensation dryer based on the Peltier element, built-in peristaltic pump for condensate removal, and large surface particulate filter. The SmartCEMS® MD3 gas dryer can be supplied mounted onto the same plate than the SmartCEMS® gas analyser or mounted on its own plate with its associated power supply. This allows locating the SmartCEMS® MD3 gas conditioning unit located directly at the sampling point.

Compact Wall Mount System

4 sensors (NDIR and electrochemical) – Up to 8 sensors in an extreme, unique configuration.
Large display with backlight, 4 lines x 20 characters.
Different types of gas dryers to fit the customer’s needs.
Application specific features and configurations (BTU, compensation, velocity).
Large selection of IO options.
Data-logger with SD card for results’ collection – Communication with PC via different interfaces (USB, LAN, RS485 and MODBUS).
Various operation modes: continuous measurements, time based, controlled with digital input, redundancy and multistreams monitoring.
Powerful PC program to adjust the analyser’s settings and to view the results.
Large range of add-ons and accessories.

SmartCEMS® Multipoint Monitoring

SmartCEMS® Twin Split Version is a Cold Dry Multipoint CEMS which uses two MD3 dryer with their own power supply added on separate mounting plates enabling measurements from two different locations (each dryer is installed near the sampling point). User programmable sampling sequences.

SmartCEMS® – Tailored to TODAY’s CEMS requirements

Typical Applications

Process gas and emissions monitoring in combustion plants, boilers, syngas, biogas, waste recycling facilities (Waste to Energy) and associated filtration systems are typical applications for the SmartCEMS® multiple gas channels configuration.

LARGE COMBUSTION PLANTS

In coal and gas fired power stations, cement kiln, foundry, paper mills… subject to regulatory requirements for emission monitoring and reporting. The SmartCEMS® enables efficient and flawlessly compliance for a large range of contaminants.

Gas Treatment Centres

Accuracy and high reliability in harsh conditions of operations makes the SmartCEMS® a powerful optimisation tool for waste recycling facilities (incinerator, water treatment plant).

SCR and SNCR Selective non-catalytic and catalytic reductions are designed to reduce the emissions of NOx by injecting ammonia is directly injected at the combustion chamber exhaust. This process causes the nitrogen oxides to react with the ammonium and turn into nitrogen and water. The SmartCEMS® is suited to upstream and downstream SNCR/SCR monitoring and provides plants operator with accurate data to control NOx regulatory emissions while optimising the denitrification process with upstream NOx measurements.

GTC and flue gas scrubbers reduce the emissions of acid gases such as SO2 with pulverised lime powder or solutions while the discharge of heavy metals and organic pollutants is controlled with the addition of activated carbon. Online monitoring of O2, SO2 upstream of the GTC allows reducing the quantity of reagents injected.
