Predict Heat Exchanger Fouling
Reduce the downtime of heat exchangers by building predictive
maintenance programs and digital twins with MATLAB
leaning heat exchangers is expensive. Maintenance can cost
hundreds of thousands of dollars annually. However, operating
a fouled exchanger affects the energy efficiency of the process
by requiring additional utilities such as steam and natural gas.
Hence, it is important to clean neither too often (too costly and
higher HSSE risk) nor too infrequently (higher operational cost
and low efficiency). Implementing a predictive maintenance program
can address these issues. By estimating the remaining useful
life (RUL) of exchangers, process engineers can take timely
action to both prevent unexpected equipment downtime and reduce
unnecessary maintenance expenditures.
Key to developing a predictive maintenance program is having
a finely tuned first-principles model for the heat exchanger
along with appropriate
sensor data. MATLAB allows
engineers to build
models of heat exchangers
using prebuilt libraries of
equipment. Simulink and
Simscape allow engineers
to perform rigorous heat
and mass transfer calculations
and incorporate pressure
and temperature-dependent behavior of fluids. They can also
assess the effect of temperature on component and process-level
C
performance. By tuning
the model to match sensor
data using Simulink
Design Optimization, engineers
can create a physics-driven, up-to-date representation of
the heat exchanger in the field. This digital twin is then operationalized
to make accurate predictions of heat exchanger performance.
Once the digital twin is created, Predictive Maintenance
Toolbox lets users estimate the RUL of exchangers. The toolbox
provides multiple functions and an interactive app for extracting
and ranking features for exploratory and predictive analytics.
Failure criteria for components, including time, pressure, or temperature-based
conditions, can be specified, allowing engineers
to track system changes and determine the presence of anomalies
and faults. This approach enables the detection of any drift in the
operation of the heat exchanger so that operational issues, such
as fouling, and off-spec products can be mitigated.
Engineers and operators need to use the validated digital twin
in an operational environment. Standalone executable applications
and dashboards can be created with App Designer and MATLAB
Compiler. This way, models built in MATLAB can be either deployed
onto the DCS or shared with anyone via an internal web application
without involvement by IT.
