Boiling Liquid Expanding Vapor Explosion (BLEVE): An Introduction to Consequence and Vulnerability Analysis in the Chemical Engineering Curriculum


  • C. Téllez University of Zaragoza
  • J.A. Peña University of Zaragoza


The objective of this article is to familiarize the student with risk analysis in the process industries.  The case selected to introduce ChE students to risk analysis is a Boiling Liquid Expanding Vapor Explosion (BLEVE) of a tank truck of liquid propane.  The blast and thermal effects (consequence analysis) have been calculated by several methods.  The vulnerability to persons and/or installations affected has been calculated using the Probit methodology.
