| Emerson
Process Solutions’ Hydrocarbon and Energy Industry Center created
KC-CEMS: a complete package for continuous and predictive emissions
data collection, storage, and retrieval. This advanced data acquisition
and reporting system (DARS) addresses the specific requirements of
environmental regulatory monitoring and reporting for stack emissions. |
| |
| The
Challenge |
|
| The
challenge in managing stack emissions is meeting stringent dynamic
requirements for continuous emissions monitoring system (CEMS) and
predictive emissions monitoring system (PEMS) reporting. A system
that is reliable, sometimes sacrifices flexibility. |
| |
| The
Solution |
|
| KC-CEMS
is a revolutionary monitoring, storing, and processing technology.
Integrating the latest programmable logic controller (PLC) and human
machine interface (HMI) technologies with a relational database reporting
application, KC-CEMS meets the data collection and reporting requirements
of USEPA 40CFR Part 60 and Alberta CEMS Code REF 107. It is customizable
for specific regional and local emissions rules. |

Benefits |
|
| |
|
|
| |
The
client/server architecture and open systems design of KC-CEMS ensures
reliability and flexibility without compromise. The robust application
and hardware platform, which are gauged to meet our customers’
specific requirements, ensures reporting needs are achieved without
expensive development costs. Configuration changes and inhouse maintenance
are important considerations in the design. A friendly, configurable
approach permits source additions and changes. We also offer remote
technical support, if required.

Technology
Expertise |
|
| |
|
|
| |
The
customizable, robust design of KC-CEMS features several technology
advantages.
|
|
| |
PLC
Interface and Control |
|
| |
KC-CEMS
uses a PLC to interface with analyzers and flow meters, gather data,
calculate and store averages, perform daily auto-calibration drift
checks, and control stream sampling for time-shared analyzer configurations. |
|
| |
HMI |
|
| |
Data
from the PLC, including proactive warnings of impending permit violations,
is displayed to the operator through a feature-rich HMI. The design
includes: |
|
| |
•
operator settings and data entry |
|
| |
-
operator-set warning alarm setpoints
- daily calibration drift schedule |
|
| |
-
calibration gas data |
|
| |
•
measured and recorded values
- NOX, SOX, CO, H2S, NMHC ppm
- NOX, SOX, ppm @ 3% or 15% O2
- NOX, SOX mass rates |
|
| |
•
real-time and historical trending
- emissions concentrations
- emissions mass flow rates
- fuel and stack rates |
|
| |
•
typical alarms and statuses
- CEM in manual or auto calibration mode
- auto-calibration drift check fail
- excessive analyzer drift (out of control) |
|
| |
•
standard reports
- shift (raw data)
- daily hour, monthly hour, monthly day, yearly
month, and quarterly summary
- event (alarms and status) |
|
| |
Hardware
Scalability |
|
| |
KC-CEMS
is scaleable from a self-contained, single computer package for small
sites to a multi-node, network version for large or multiple plants. |
|
| |
Client/Server
Design |
|
| |
The
KC-CEMS architecture uses an open systems design philosophy in both
single- and multi-node versions. KC-CEMS’ robustness and flexibility
ensures that the product will not be superseded by a change in technology. |
