RADIATION SCAVENGING OF ACETYLENE DISSOLVED IN LIQUID OXYGEN, PART 1. IN-PLACE CLEANING OF PIPING SYSTEMS, PART 2.

Abstract

Destroying acetylene dissolved in liquid oxygen by irradiation with gamma rays was investigated. It was found that 94-98% of the acetylene in a saturated solution of acetylene in oxygen was removed in 8 hours at a dose rate of 80,000 rads. On this basis calculations indicated that a 5 kilocurie source of Co(60) or a 7.8 kilocurie source of Cs(137) would prevent any build-up of acetylene in a 28,000-gallon tank for a 10-year period. The most effective means of removing or passivating hydrocarbon contaminants in missile handling systems were investigated. Various experimental methods--treatment with gaseous fluorine, fluorination in Freon solutions, electrochemical fluorination, and vapor phase degreasing with Freons-were investigated. It was concluded that vapor phase degreasing with Freons is the most promising means of cleaning a system, and a discussion is given of the various problems encountered in the use of this method.
