Edwards CLF3

Chorine Trifluoride Ton Container Management

This project entailed chemical neutralization of three materials that were formerly investigated for use as liquid rocket propellant oxidizers located at Edwards Air Force Base.  The project required the management of 27 cylinders containing oxygen difluoride, 16 one-ton containers of chlorine trifluoride, 1 cylinder of chlorine trifluoride, and 1 cylinder of perchloryl fluoride.

All of the target containers had been in storage since their use as a rocket propellant was investigated during the 1950's and 1960's.  Since that time, the materials had been held in storage in anticipation of future research and even pilot scale operations.  In the absence of further development, the materials were viewed as a liability due to their high reactivity and toxicity.

Removal of these dangerous chemicals to an off site commercial disposal facility would require transported over public thoroughfares and through potentially populated areas.   Such an activity would pose logistical and permitting concerns.  Due to these concerns, IES was asked to  provide personnel and equipment to neutralize the chemicals on site.                                    

IES proposed onsite neutralization of the various target materials and developed processing information for the local and state regulatory review.  When the project received the environmental permits, IES mobilized a three man crew. Given the quantity of material, IES rented large tanks from local vendors and took delivery on bulk quantities of reagent.

Processing went as anticipated but was routinely interrupted by wind conditions which, by regulation, required the work to cease.  Winter weather, which included cold temperatures and snow contributed to the difficult conditions.
 
The crew was challenged by inoperable valves.  The low vapor pressure of the target gases favored accessing by tap and saddle.  However, the gas itself had the potential to react with metal shaving and with the unpassivated steel tap with the end result being fire.  IES had developed procedures to minimize this potential and they worked without fail.  The extraction of target material by tap would necessarily had required the processing of gas vapors.  This would had required an inordinate amount of time particularly in view of the cold ambient temperatures.  IES had developed a procedure of inserting a dip tube into the tapped hole and extracting the material in liquid phase.  This proved to be very efficient.

Despite weather related interruptions, the project was completed on time and without incident.
