OIL CONTAMINATION IN OXYGEN SYSTEMS

Abstract

A test program was conducted to determine the ignition limits of oil contamination in 1/2 in. monel pipe when pressurized with 3000 psi oxygen. The oils investigated were 2190 lubricating oil and Habcool No. 318 cutting oil. The test results showed little danger of compression ignitions at oil concentrations below 160 mg./sq ft of 2190, or below 110 mg./sq ft for Habcool. Concentrations of both oils above 260 mg./sq ft will ignite when rapidly pressurized with 3000 psi oxygen. The results also showed that ignition will not occur with oil droplets or puddles smaller than 100 microl in size and that a pressure rise greater than 25% will not occur below oil concentrations of 500 mg./sq ft. As a result of this test program, it is recommended that the oxygen clean standards be relaxed to 1.5 mg./sq ft.
