Products
SAChE Products can be used and adopted to learning environments including students in many different fields (such as chemical and mechanical engineering as well as chemistry and materials science) and practicing engineers (such as in safety training programs). We attempt to put the materials in an easy to use format, and modifications can be made to the materials to fit the circumstances.

Runaway Reactions -- Experimental Characterization and Vent Sizing
Sponsors
Description
This module is an updated and revised version of the module entitled “A Unit Operations Laboratory Experiment for Runaway Reactions”, published by SACHE in 2001. The title has been changed to reflect the more general utility of the module for education, training and instruction of personnel in industrial, governmental or other laboratories who are concerned with the characterization and sizing of relief vents for runaway reactions, in addition to universities who would like to include this subject matter in lecture and/or laboratory courses concerned with process safety.
The Advanced Reactive Screening Tool (ARSST) is an easy to use and cost effective calorimeter that can be used to quickly and safely identify potential chemical reactivity hazards. It can also yield critical experimental data on the kinetic characteristics of runaway reactions that can be scaled up to full scale process conditions and can be used directly to estimate the size of a relief device that would be required to protect the reactor against the over-pressure that would result from a runaway reaction.
This instruction module describes the ARSST and its operation, and illustrates how this instrument can easily be used to experimentally determine the transient characteristics of runaway reactions, and how the resulting data can be analyzed and utilized to size the relief vent for such systems. It can also be easily incorporated into a Chemical Engineering Unit Operations Laboratory as an effective educational laboratory experiment utilizing a practical and physically realistic example reactive system.

Solutions to Student Problem Set Volume 1
Sponsors
Description
"Safety, Health, and Loss Prevention in Chemical Processes - Problems for Undergraduate Engineering Curricula" Volume 1 was originally published by CCPS in 1990. Copies were given to universities and sold to industry. This was a very popular and valued product that is currently out of print. J. Wagner (Oklahoma State University) recently put this product in electronic format for distribution here. The problems are available via the Links menu on this site and to students logged into the site.
The 90 problems involve issues of safety, health, and loss prevention and provide students and new engineers with important insights to industrial processes. This material can also be used as a reference for industrial courses for new engineering employees. These safety problems and solutions further demonstrate that safety and health issues are handled with basic engineering principles and logic. Finally, through the use of this material, we hope to instill in students and engineers an increased recognition of the importance of chemical process safety and the recognition that they have the professional and ethical responsibility to provide safe chemical plants, processes and products.
The problems were designed to use in existing engineering courses, such as: stoichiometry, material balance, mass transfer, heat transfer, thermodynamics, process control, and design courses. The authors believe that it is important that students work on these problems while attending there undergraduate courses and throughout their education. This process should develop a safety culture within engineers that will help them throughout their careers.

Description
"Safety, Health, and Loss Prevention in Chemical Processes - Volume 2" was originally published by CCPS in 2002 and distributed to SACHE University Members. This was a very popular and valued product that is now out of print. R. Willey recently put this volume in electronic form for distribution here. The problems are available on the Links menu on this site and to students logged into the site.
Like the Volume 1 problems, the 218 problems teach safety, health, and loss prevention. This solution set represents problems and solutions produced by SACHE in the period 1990 to 2000.
The problems were designed for use in existing engineering courses, such as: Stoichiometry, Thermodynamics, Fluid Mechanics, Kinetics, Heat Transfer, Process Dynamics and Control, Computer Solutions, and Mass Transfer. The authors believe that including these problems in a required undergraduate course helps engineering students develop a safety culture and mind set that will benefit them throughout their careers.
