Predictive Maintenance Makes Refineries Safer
Ensure the mechanical integrity of critical process equipment with cost-effective predictive
maintenance programs
hrough OSHA-compliant process safety
management standards, petroleum
companies aim to prevent the release
of chemicals that may ignite, cause fires
and explosions, or have toxic impacts.
Mechanical integrity is chief among process
safety management elements because it covers
the maintenance of process equipment,
including pressure vessels, piping systems,
valves, pumps, and more. The key to maintaining
mechanical integrity within a large
chemical plant is to implement a successful
predictive maintenance program.
Predictive maintenance enables process engineers to monitor
the health of their process equipment, estimate machines' remaining
useful life, and pinpoint the root causes of problems before critical
failure. Unlike preventive maintenance-which relies heavily on
maintenance schedules and frequently takes equipment with usable
life offline-predictive maintenance is more cost-effective because
it helps engineers find the optimum time for maintenance.
Many engineers in the refining industry use MATLAB® and

Designing the condition indicators using
Predictive Maintenance Toolbox
Predictive Maintenance Toolbox™, engineers
can design condition indicators
using signal-based or model-based approaches.
Using condition indicators,
machine learning models can be trained
to detect anomalies, classify different
types of faults, and predict the transition
from healthy state to failure. Many
built-in functions are available to simplify
basic preprocessing, filtering, and
preprocessing in the time, frequency,
and time-frequency domains.
Simulink® products for predictive maintenance algorithm development
and deployment steps.
To develop a predictive maintenance algorithm, chemical engineers
must first preprocess raw equipment data to extract condition
indicators and distinguish between healthy and faulty conditions.
Preprocessing is often a time-consuming step. With MATLAB and
Another predictive maintenance challenge is aligning hardware
data with different sampling rates-specifically, accounting for
missing data, outliers, and insufficient data to cover various operating
conditions. Engineers can generate synthetic data for various
operating conditions through parameter estimation and process
equipment modeling in Simulink to build robust predictive maintenance
models without having a large data set featuring healthy and
faulty operations.
MATLAB and Simulink help chemical industry engineers create
and scale effective predictive maintenance programs that ensure
the mechanical integrity of their equipment and create safer processes.
Additionally, these predictive maintenance models can easily
be deployed to hardware or IT/OT systems to share the results
with plant operators.
