MATLAB and Simulink for the Chemicals and Petrochemicals Industry

Process engineers use MATLAB® and Simulink® to analyze real-time sensor data, implement control strategies, and create predictive maintenance systems based on big data and machine learning.

MATLAB and Simulink help process engineers:

  • Develop predictive maintenance systems by applying numerical techniques on high-speed sensor data
  • Use machine learning with historical data to troubleshoot process problems
  • Use data modeling to improve process performance 
  • Develop and implement advanced predictive control (APC) strategies
  • Adopt digitization without depending on data scientists or IT personnel 

"As a manufacturing company we don’t have data scientists with machine learning expertise, but MathWorks provided the tools and technical knowhow that enabled us to develop a production preventative maintenance system in a matter of months."

Dr. Michael Kohlert, Mondi Gronau

Beyond Process Simulators

Traditional process simulators are generally sufficient for steady-state conditions, but they cannot handle the dynamic nature of the inputs that real plants deal with. With MATLAB, you can write your own equations and algorithms, giving you full control over the entire model.

You can also integrate MATLAB with process simulators like Aspen Plus and gPROMS for custom unit operations, advanced analytics, designing control schemes, and exploiting optimization routines such as genetic algorithms.

Optimize Assets with Predictive Maintenance and Signal Processing

MATLAB can help you develop predictive maintenance algorithms customized to the specific operational and architectural profile of your equipment. Use Predictive Maintenance Toolbox™ to design condition indicators and estimate the remaining useful life of your rotary equipment.

You can use Signal Processing Toolbox™ to automate the monitoring of performance of your control loops, remotely determine the extent of corrosion or pitting in your pipelines, and detect the location and quantity of pipeline leaks.

Machine Learning and Big Data

Interactive apps in Statistics and Machine Learning Toolbox™ let you apply machine learning techniques without having to be an expert in data science. MATLAB also provides a single, high-performance environment for working with big data – be it structured or unstructured. This enables you to perform fault detection and diagnosis faster and better monitor your processes.

Read how Ruukki engineers reduced their analysis times from several days to less than a minute by integrating various databases and using machine learning for process optimization.

Image Processing and PDEs

Use Image Processing Toolbox™ apps to automate common processes like segmenting image data and batch processing large image data sets. You can use MATLAB in image processing applications such as flame characterization, thermal imaging of equipment, and plastic film quality inspection. With deep learning in MATLAB, you can learn feature representations directly from image and video data.

Use the functions in Partial Differential Equation Toolbox™ to quickly solve heat and mass transfer equations and partial differential equations (PDEs) using finite element analysis. The toolbox speeds up your analysis by allowing you to solve PDEs in just a few lines of code.

Process Improvement with Data Modeling

Use multivariate analysis tools in MATLAB to determine the independent driving variables affecting process performance. System Identification Toolbox™ lets you create and use models of dynamic systems that are not easily modeled from first principles or specifications. The toolbox also lets you interactively perform online parameter and state estimation. 

Watch how Shell used MATLAB (3:35) to develop models and perform real-time optimization on a batch process.

Develop and Implement APC Strategies

You can use MATLAB controls products to design controls schemes and perform dynamic simulations for better analysis of plant behavior. Validate your design with hardware-in-the-loop testing and rapid prototyping.

Controls engineers can also embed process models from Aspen Plus and gPROMS into Simulink. In this way, you can redeploy existing models to design a control strategy in your preferred environment.

Digitization

MathWorks can help you adopt and implement big data strategies specific to the needs of your organization. You can use prebuilt MATLAB toolboxes and reference architectures to simplify a wide range of applications: from integrating with enterprise IT systems, the cloud, and production data infrastructure to scaling your computation to clusters or deploying your models as applications to share with non-MATLAB users.

See how you can connect directly with OSIsoft PI systems and enable real-time operational intelligence. 

Watch how Shell embraced digitization (29:14) using MATLAB Production Server™. Shell engineers automated their processes for integrating data from different sources, building models, and deploying their analytics onto cloud and enterprise systems.

Simplify Planning and Scheduling Activities

Improve efficiencies in production and scheduling through discrete event simulation. With SimEvents™, you can study the effects of task timing and resource usage in a batch production process. Using MATLAB and Simulink products, you can also conduct operational research for decisions related to forecasting, capacity planning, and supply-chain management.

Read how SK Innovation developed an optimal crude selection strategy at their refinery using optimizers in MATLAB.

“Another advantage of developing our own system in MATLAB and Simulink is that we can capture the organizational knowledge and expertise accumulated by Johnson Matthey engineers rather than relying on another company’s one-size-fits-all solution.”
