Chapter 13: Unsteady State Nonisothermal Reactor Design

The ARSST: Testing for Runaway Reaction Temperatures


The Advanced Reactive System Screening Tool (ARSST) is a batch reaction used to identify potential safety hazards.  It consists of a well instrumented batch reaction that is heated in such a manor so as to raise the temperature at a uniform rate.  It is primarily used for liquid phase reactions.

For more information, visit www.ARSST.com

 

A batch reactor is heated by an external heater at a rate of 0.2 C/min. Plot T vs. t and find the ignition temperature.

 

Solution

For
dividing by V,

Using Polymath to Solve:
The ignition temperature is approximately 338K.
