Title: Custom Built System for Deflagration/Detonation Determination of Gaseous Mixtures
Client Challenge:
This project required evaluating the stability of ClF3 and F2 flammability with fluorocarbons, and tested flammability of propane with air over a range of temperature.
MCL Approach:
Explosivity testing determines the flammability limits (both upper and lower) of gaseous chemicals or fuels with oxidants. These limits are a measure of the fire and explosion hazard associated with the gases and may be used to prevent and mitigate explosions through gas composition control and equipment design. The flammabilities of gaseous and liquid chemicals are measured at initial pressures from subatmospheric to several atmospheres. The initial test temperatures can range from ambient to over 575 °F. Tests are conducted according to ASTM E-918-83 (Reapproved 1993) Standard Practice for Determining Limits of Flammability of Chemicals at Elevated Temperature and Pressure.
MCL custom built a system to determine the deflagration/detonation of gaseous mixtures as per the specific testing requirements of the client. This system was employed in the testing of ClF3 and F2 flammability with fluorocarbons. Subsequently, similar flammability tested of propane with air was conducted. This project demonstrates MCL’s ability to work safely with uranium hexafluoride and other highly corrosive materials.
Outcome:
The client was able to accurately assume the deflagration, detonation, and flammability potential of gaseous mixtures at various concentrations and temperatures.
