Ease of Operation & Maintenance
AMP-Cherokee’s Walk-in Extractive
CEMS can be customized for wall-mount or instrument rack components. Our
walk-in shelters are available for either general purpose or explosion proof
applications.
The local touchscreen HMI interface
and plug-and-play functional design sets a new standard in reliability and ease
of operation.
System Redundancy
System uptime is
protected, with numerous redundant sampling features available as follows:
• Redundant SQL databases (standard)
• Redundant local and remote data logging
(standard)
• Redundant sample, blowback, and calibration
tubing (standard)
• Redundant secondary filtration (standard)
• Redundant pre-cooler (standard)
• Redundant analyzers used as standby or back-up
(optional)
• Redundant monitoring
utilizing integrated PEMS module
(optional)
Parameters Monitored
AMP-Cherokee CEM systems
can be configured to monitor for one or all of the following:
• NOx • SO2 • CO2 • O2 • CO • THC • TRS • Hg • H2S
• HCl • HF • NH3 • Opacity • Volumetric Flow • Moisture •
Particulate
Background
There are three general types of
CEMS as follows:
• In-situ: the measurement is performed in the stack or duct
• Direct Extractive: sample pump draws sample from the stack and delivers it to
the CEMS
• Dilution Extractive: a precision eductor extracts a sample from the stack while
diluting it and then delivers the diluted sample to the CEMS
Predictive Emissions Monitoring Systems (PEMS)
A fourth type of emissions
monitoring called Predictive Emissions Monitoring (PEMS) has emerged in the
last decade which is a software based technology that uses sensor inputs from
the process unit (boiler, turbine, etc.) to predict pollutant emissions. All
four types of emissions monitoring have been approved by EPA and state
regulatory agencies and are widely used throughout the United States.
Data Acquisition and Handling System (DAHS)
AMP-Cherokee is one of just a few
CEMS integrators that offers our own Data Acquisition and Handling System
(DAHS) software, ProLogix. ProLogix is the only DAHS on the market which has an
integrated PEMS module that can be used as follows:
