  • Aspen Exchanger Design & Rating Family

    A family of products to model process heat exchangers from cost optimized designsto rating and simulation

    Heat exchangers can comprise up to 30% of capital equipment and impact 90% of the energy used ina petrochemical process. Major savings are available by implementing best practices with the AspenExchanger Design & Rating (Aspen EDR) product family.

    The Challenge: Simplifying the Engineering Lifecycle

    Conventional workflow for the design of heat exchangers requires manual data transfer from process engineer to thermal and

    mechanical experts to a cost estimator. The design cycle involves several iterations and is prone to data transcription errors.

    This approach also excludes the process engineers visibility into problem details, making it difficult to investigate multiple

    process scenarios to arrive at a fully optimized process.

    The AspenTech Solution: Minimize Capital Cost and Improve Process Design

    The Aspen Exchanger Design & Rating (EDR) product family provides the industrys most comprehensive suite of programs for

    heat exchanger design, simplifying the engineering cycle through a single, integrated framework. Companies deploying these

    solutions reduce capital equipment cost and engineering man-hours, optimizing the operation of their processes.

    High degree of accuracy

    Aspen HTFS Research Network

    Aspen HTFS Research comprises both on-going experimental study and expert analysis to develop

    AspenTechs proprietary theoretical models and correlations, ensuring your exchangers are designed to the

    highest degree of accuracy. Customers may license access to the Aspen HTFS Research Network 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 worlds 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 providing accurate

    equipment design calculations.

    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,

    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 six products that comprise 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 various

    heat exchangers. Access to AspenTechs world class property package with more than 25,000 components and

    35+ vapor equilibrium methods is accessible through each program.

    Aspen EDR product family uses the power and flexibility of the Microsoft Windows environment, allowing you

    to fully explore unit geometry and performance detail. It supports drag & drop interfacing with Microsoft

    Excel as well as high-level communication with other software and is tightly integrated with Aspen Simulation

    Workbook, providing easy and robust case studies within Microsoft Excel.
