Chemical Process Modeling And Simulation
Simplified Introduction
Chemical Process Modeling and Simulation
What do we do?
• Perform mass and energy balance across various unit
operations and processes
• Mass Balance 
•
Raw Material requirement
• Product and by-product formation
• Waste formation
• Energy Balance 
•
Energy required
• Opportunity for energy saving

Key- areas
Approach to plant performance improvement/ revamp/ modification/
optimization
Typical steps involve:
•
Collect Data form plant or lab
•
Develop, Calibrate and Validate Process Simulation
Model using Plant/Test Run/Lab data
•
Define target performance
•
Perform Optimization, Sensitivity and Parametric
Studies and identify optimum solutions that meet
target performance with the lowest cost of
implementation
•
Estimate revamp/modification project cost and
perform benefit/saving/payback analysis to customer
to enable them in their decision-making process.
•
Help customers implement the modification and
achieve target performance.
