Aspen Plus – Basic Process Modeling (Very Recommended)
Aspen Plus – Intermediate Process Modeling (Somewhat Recommended)
Description

This BOOTCAMP will show you how to model and simulate common industrial Chemical Processes.

It is focused on the “BOOTCAMP” idea, in which you will learn via workshops and case studies, minimizing theory to maximize learning.

You will learn about:

Better Flowsheet manipulation and techniques
Understand Property Method Selection and its effects on simulation results
More than 15 Unit Operations that can be used in any Industry
Model Analysis Tools required for process design
Reporting Relevant Results Plot relevant data
Analysis & Optimization of Chemical Plants
Economic Analysis
Dynamic Simulations
At the end of this Bootcamp, you will be able to model more industrial processes, feel confident when modeling new processes as well as applying what you have learnt to other industries.

This is a slideshow / resource / support material of the course. Get full access (videlectures) https://www.chemicalengineeringguy.com/courses/aspen-plus-bootcamp-with-12-case-studies/ x-x-x Requirements Basic understanding of Plant Design & Operation Strong Chemical Engineering Fundamentals Aspen Plus V10 (at least 7.0) Aspen Plus – Basic Process Modeling (Very Recommended) Aspen Plus – Intermediate Process Modeling (Somewhat Recommended) Description This BOOTCAMP will show you how to model and simulate common industrial Chemical Processes. It is focused on the “BOOTCAMP” idea, in which you will learn via workshops and case studies, minimizing theory to maximize learning. You will learn about: Better Flowsheet manipulation and techniques Understand Property Method Selection and its effects on simulation results More than 15 Unit Operations that can be used in any Industry Model Analysis Tools required for process design Reporting Relevant Results Plot relevant data Analysis & Optimization of Chemical Plants Economic Analysis Dynamic Simulations At the end of this Bootcamp, you will be able to model more industrial processes, feel confident when modeling new processes as well as applying what you have learnt to other industries.
