Shell and Tube Heat Exchanger Design Using Aspen EDR Software

Minimize Capital Cost and Improve Process Design

The Aspen Exchanger Design & Rating product family integrates rigorous process models with the industry’s most comprehensive heat exchanger modeling capabilities.

Benefits include:

• Typical savings of 10-30% on the equipment cost per heat exchanger.
• Potential savings of millions of US dollars annually through integration with Aspen Plus® and Aspen HYSYS® to identify areas to reduce energy, capital and operational costs.
• Increased engineering efficiency, particularly fast-track front-end engineering, through fully integrated tools for process design.

Aspen HTFS® Research Network

Aspen HTFS Research Network compiles AspenTech’s proprietary theoretical  models

and correlations developed through more than 40 years of experimental  study and analysis. Customers  can access the research  network from Aspen EDR to validate their design practice against documented methods, models and source data

Best-in-Class Physical Properties Methods and Data

The Aspen EDR product family accesses the world’s largest database of pure component and phase equilibrium data for conventional chemicals and electrolytes.  The database is regularly updated  from the U.S. National Institute of Standards and Technology (NIST), which ensures  easy access to the best available experimental  property data. Accurate transport properties and phase equilibrium data are essential  to accurate exchanger design and simulation.

Wide Range of Applications

The products facilitate the full range of practical process applications for a wide range of exchanger types including: shell & tube, double pipe, multi-tube hairpin, air coolers, economizers, plate and frame, plate fin, coil-wound and fired heaters from conceptual  design to operational troubleshooting. This flexibility allows process streams to be single phase, boiling or condensing  vapors, single component or any mixture with or without non- condensable gases in any condition.

Common User Interface

All seven products in the Aspen EDR product family operate within a common user interface which automates data transfer from one program to another, allowing engineers to compare the advantages of different exchanger types. Access to AspenTech’s world class property package with more than 25,000 components and 35+ vapor equilibrium methods is accessible in each program.

The Aspen EDR product family uses the power and flexibility of the Microsoft® Windows environment, allowing you to fully explore unit geometry and performance detail. Products support “drag & drop” interfacing with Microsoft Excel® as well as high-level communication with other software and the programs are tightly integrated with Aspen Simulation Workbook, providing easy and robust case studies within Microsoft Excel.
