Shell and Tube Heat Exchanger System

July 26, 2022 06:18 PM
Two of the three shell and tube heat exchanger systems are pictured above. They each consist of a tank, pump, and heat exchanger. The flow though the tube side is measured and controlled and the steam pressure is also measured and controlled. Other variables are also controlled and measured via a Labview interfaced with a National Instruments cRIO-9074 interface.

Run the Shell and Tube Heat Exchanger System #1!


In order to run the experiment, you need to be onsite at BYU in the Clyde Building room CB217A. There you will log onto a CAEDM computer and use the Pale Moon browser to go to the following link:

Run S&T #1

  1. Ensure that you fully understand how to operate the equipment safely.
  2. Request control by right clicking on the graphical user interface (gui) after clicking on the above link in the Pale Moon browser.
  3. Remember to not run the pump without sufficient water in the tank. Also, please do not open the manual steam valve without water flowing through the system.
  4. Turn off the steam valve manually before stopping fluid flow. Then verify the fluid temperature is less than 50 C before ceasing fluid flow.
  5. Release control by right clicking on the graphical user interface after safely shutting down the equipment.

Catalytic Methanation System

Catalytic Methanation System

The catalytic methanation experiment consists of a catalytic reactor, a gas analyzer, and three gases (carbon dioxide, hydrogen and helium). The flow of those gases is controlled as is the reactor temperature. Control is by custom Labview software using a National Instruments cRIO-9074 chasis.

Problem Based Learning Projects

The Problem Based Learning lab requires students to build and operate a fluid flow system with a tank, pump, valves, and piping to achieve a defined objective. Labview is also used together with a labview chasis to program a control system with data collection.
