Getting Started with Coil Wound Heat Exchange in Aspen Exchanger Design and Rating 1: Creating a Coil Wound Simulation

Description

Begin with Aspen EDR, learn how to create a new Aspen Coil Wound model, then become familiar with the application user interface and capability, while discovering best practices before building a case.

About the Series

Coil Wound heat exchanger, also known as Spiral Wound or Wound Coil exchanger, is a principal heat transfer equipment in LNG process. Using Aspen Coil Wound, available in Aspen EDR from V9.1 and beyond, you can rigorously rate and/or simulate Coil Wound Exchanger.

In this Getting Started series, you will learn how to simulate a multi-stream heat exchanger using Aspen Coil Wound. Using the provided inlet conditions, stream compositions, and exchanger geometry data in Coil Wound Getting Started Guide provided in the product documentation, you will build a simulation case to determine the outlet conditions of the streams.

1.     Creating a Coil Wound Simulation

2.     Configuring Stream Occupancy

3.     Defining Stream Process and Property Data

4.     Specifying Coil Wound Bundle Geometry

5.     Viewing Coil Wound Results

By the end of the series, you will be able to understand the model requirements, and simulate a principle heat transfer equipment in LNG process using Aspen Coil Wound.

Script: Creating a Coil Wound Simulation in EDR

Getting started with Aspen Coil Wound in Aspen EDR, available in V9.1 and beyond. In this video, I will show you how to create a Coil Wound model

But first, for those of you who may not be as familiar with EDR, it allows you to create a new model by clicking File | New. Or recently opened cases associated with the Recent command. Or restart from an existing model by navigating to the file using the Open dialog.

Let's start a new Coil Wound model. To do this, Click New right from the main window. Select Coil Wound Exchanger and click Create.

Using Aspen Coil Wound, you can: rigorously simulate and/or rate a Coil Wound Exchanger. Simulation calculations predict outlet conditions, heat transfer, and pressure drop.

Checking or Rating mode answers the question whether if a given exchanger can provide the desired service.

In terms of inputs, both run modes require similar amount of information: occupancy, process data - that is the inlet and outlet conditions - stream compositions are typically composed of refrigerants and natural gas - and finally, exchanger geometry that you receive from the manufacturers.

Note the units of measurement. All of the Aspen EDR programs defaults are in traditional U.S. units.

I recommend reviewing the units of measurement for your data before getting started. If you need to adjust the global unit setting, do so now by using the Set Units option on the Home Ribbon Unit group. From the drop-down menu, choose your desired unit. For examples, here I will select SI unit set to reflect my data.

If desired, you can also set the default Units of Measure from File | Options | General, and select from the drop down menu here.

Finally, all EDR applications offer context sensitive product help. You can access the help at any time by pressing F1.

For other kinds of information, use the commands on the application Resources tab on the Ribbon.

Playing the Viewlet

A Viewlet is an animation sequence constructed by capturing a series of screen shots from a software application. Viewlets are used to demonstrate product features and to train users in simple procedures.
