Objective:
Build a flow cart that would illustrate
process control to future chemical
engineering students here at RIT.
Controls based on temperature feedback
loops must be incorporated.
Temperature changes used for process
control were achieved through the use of
a shell-and-tube heat exchanger.

Description
Water bath limited to a max of 0.5 GPM
Bath will operate between -4° F and
392° F
Bath will operate between -4° F and
392° F
Design for safe operation
Design for use by three students
during allotted lab time
Portable
Easily connected/disconnected
for lab use
Robust design
Minimal maintenance
requirements
Utilize a control loop based on
temperature changes
Require control of heated
process flow and cooling
exchange flow rates
Operate both manually and
through process control
programming in Labview
Capable of manual and
automatic data collection
Operating Requirements:
•
•
•
•
•
•
•
120 VAC for Instruments and Controllers
25 psi instrument air
80 psi compressed air
Fluid viscosity between 1 cP and 10 cP
Process mass flow rate between 500 g/min and 1500 g/min
Temperature range for process effluent of 70 °F and 130 °F
Heating fluid flow (water) rate between 1 GPM and 4 GPM
Status Key
Specification Met
Working exception to specification, will not negatively impact functionality
Needs to be addressed in order to function as required
Final Conclusions:
• Finished cart successfully provides a learning tool for students
to use a temperature feedback control system
• Delivered cart includes a Labview interface for students to
interact with the system.
Special Thanks to: Faculty guide Steve Possanza, the RIT
Chemical Engineering Department and Kodak for their
generous contributions.
