 Continuous
Emission Monitoring System
Emerson Process Management understands the challenges our clients face
when meeting today’s stringent and dynamic requirements for CEMS
and PEMS reporting. Using our knowledge of PLCs and Data Acquisition
Systems, we provide a total solution approach for continuous, predictive,
and enhanced emissions data collection, storage, and retrieval.
The specific requirements of regulatory monitoring and reporting
of stack emissions are addressed by our data acquisition systems
(DAS).
Environmental Monitoring
Emerson Process Management introduces KC-CEMS, a complete package for
continuous, predictive, and enhanced emissions data collection,
storage, and retrieval. This data acquisition system (DAS) addresses
the specific requirements of regulatory monitoring and reporting
of stack emissions. Analyzer or Predictive Model data can be routed
to a PLC where calculations are performed and the results are displayed
via a modern HMI. Data is written from the HMI real-time database
directly to Microsoft SQL Server®, a robust Database Management
Systems (DBMS). Control of analyzer subsystems by the PLC is accessible
from the HMI. Time-shared and dedicated analyzer configurations
are supported. KC-CEMS is a revolutionary step in monitoring, storing,
and processing technology. Integrating the latest PLC control and
HMI with a relational database reporting application, KC-CEMS meets
the requirements of 40 CFR 60 (NSPS) and can be tailored for specific
regional and local emissions rules.
System Overview
Consisting of a Programmable Logic Controller (PLC), analyzer subsystem,
and a HMI and real-time database, our solution brings reliability
and flexibility without compromise.
The PLC interfaces with analyzers and flow meters in the analyzer
subsystem to gather data, calculate averages, control auto-calibrations,
and shift stream sampling on time-shared analyzer configurations.
The HMI is a powerful and flexible interface that provides adjustable
controls, measured and recorded values, real-time and historical
trending, and real-time alarming.
The collection of data via the real-time database allows for daily
reports averaged for last 24 hours, monthly reports, daily and monthly
exception reports, and quarterly reports including three month emissions
summary, maintenance data for each train, and quarterly emissions
exceptions.
Hardware Scalability
Scalable from a self contained, single computer package for small
sites to a multi-node network version for large plants, KC-CEMS
hardware and software can be configured to meet the needs of any
size facility. Processing power can be any one of the latest PC
platforms running Windows™ NT operating systems.
Client/Server Design
Client/Server architecture utilizing an Open Systems design philosophy
in both single and multi-node versions provide a robust and flexible
product that will not be superseded by a change in technology. Simply
selecting the desired relationships from a predefined screen to
produce ad hoc reports can create custom SQL queries.
Benefits and Economics
Today’s challenges include meeting stringent dynamic requirements
for CEMS and PEMS reporting. A system that is reliable sometimes
sacrifices flexibility as a result. Client/Server architecture and
Open Systems design enable our solution to offer both reliability
and flexibility without compromise. Starting with a robust application
and hardware platform gauged to meet your particular requirements
ensures future reporting needs can be met without expensive development
cost.
Configuration changes and in-house maintenance are very important
considerations in this design. A friendly, configurable approach
permits source additions and changes to be implemented as required.
Emerson Process Management's remote support is available if necessary.
