Aspen Plate Exchanger

Design, rating and performance simulation of plate & frame heat exchangers


 

Based on the familiar Aspen HTFS user interface, Aspen Plate Exchanger provides users with a common environment for easy comparison of plate heat exchangers with shell and tube units. It is a single solution for the design, checking (rating) and performance simulation of plate heat exchangers, either gasketed plate and frame or welded or brazed plate. In design mode, it can determine the optimum heat exchanger configuration. It can also check or simulate geometrically specified heat exchangers allowing users to troubleshoot or de-bottleneck operating units.

These exchangers are used for general heating and cooling duties, including vaporization and condensation. They are also an alternative to shell and tube in many applications. Plate handles characteristics common to many commercially available plate & frame heat exchangers.

Key Technical Features

  • Program Modes
    • Design – optimizes the selection based on area
    • Checking/Rating – assesses adequate surface area and allowable pressure drops
    • Simulation – calculates heat load, outlet temperatures, and pressure drops for a given heat exchanger
    • Design for a given plate – calculates the number of plates required for a specified heat duty
  • Maximum of 5 passes for either hot or cold streams
  • Co- or counter-current flow
  • Evaluates flow maldistribution
  • Non-Newtonian fluids
  • Proper handling of fluids with two liquid phases
  • Double banking
  • User supplied Colburn j and friction factors (to model special proprietary plate types)
  • Database of commercially available plates from 3 leading suppliers
  • Outputs
    Aspen Plate Exchanger uses the power and flexibilty of the Microsoft Windows environment to allow you to explore exchanger geometry and performance detail. In addition, Aspen Plate Exchanger is designed to support “drag & drop” interfacing with Microsoft Excel, as well as high-level communication with other software.
    Thermal output includes:
    • Optimization path that identifies the design selection with smallest area, possible alternative designs, and controlling design constraints
    • Extensive warning and error reporting, alerting you to potential operational problems
    • Summary of exchanger performance
    • Details for pressure drops and hold-ups
    • Stream conditions at inlet and outlet of each pass
    • Stream conditions along the exchanger
    • Exchanger layout drawings
    • Extensive graphing capabilities
