Rupture of a Nitroaniline Reactor


Ronald J. Willey (Northeastern University)


This case study of the rupture of a nitroaniline reactor demonstrates safety concepts that are especially important to both new and experienced engineers including:
  • Runaway reactions need to be understood and appropriately controlled to prevent major losses.
  • A Safety review is an important process for identifying potential problems and developing approaches to solve the problems.
  • Redundant controls are needed in critical applications.
  • Relief systems consisting of a rupture disk followed by a spring operated relief valve must be properly installed and maintained.
  • Training operators and engineers to recognize the consequences of operating errors is important.
  • Management decisions to override safety systems must be thoroughly thought through before implementation of such action.
The lessons of this product are very important, and they will be true and relevant forever. The PowerPoint presentation in this product includes problems (with solutions for the instructor). A pdf document provides background for the presentation.
