1. Basic understanding of process engineering
2. Aspen Plus Software installed on your computer
3. Have a Computer
4. Have a Desire

In this part the instructor talks about different concepts and definitions used in Aspen Energy Analyzer and based on the definitions and the type of the example, HI Project template is selected. Then based on the general procedure proposed by Aspen Tech, he at first defines process streams, then defines utility streams and finally checks the economics of the example.

Overview

Introduction to Heat Integration Manager

Heat integration in Aspen Energy Analyzer (formerly called HX-Net) is designed for analyzing and improving the performance of heat exchanger networks (HEN). Aspen Energy Analyzer focuses on analyzing the networks from operations’ as well as design’s point of view.
HEN operations features are designed to provide you with an understanding of current plant operation and related issues such as fouling. Furthermore, fouling mitigation strategies can be studied and simulated in Aspen Energy Analyzer.
HEN design features assist the designer in understanding the gap between current operation and the thermodynamic optimum operation. Furthermore, the designer can use Aspen Energy Analyzer to identify and compare options to improve the performance and reduce the gap between current and thermodynamic optimum operations.
To perform any heat integration study from a design or operations perspective, Aspen Energy Analyzer needs the process requirements and the HEN that achieves the process requirements. The terminology that is used in Aspen Energy Analyzer is “scenario” for process requirements and “design” for the HEN.
Aspen Energy Analyzer exposes the heat integration functionality through the HI Case and HI Project operations:

• HI Case limits you to working with one scenario and one design. Thus HI Case is suitable for users who want to perform a quick energy analysis or for users who wan to study current plant operation.

• HI Project enables you to work with multiple scenarios and each scenario could have multiple designs. Thus, HI Project is more suitable for users who want to make structured modifications and compare those modifications. HI Project is also suitable for performing revamp studies.

In this part he runs the software to check the optimal designs offered by Energy Analyzer and finally investigates which one is the best design for that case.
