An investigation of hydrocarbon film ignition was started. Hexadecane was deposited on films of different thicknesses upon the inner wall of a section of 1-in. stainless steel pipe. Ignition was attempted with an electric spark and duPont electric match. The spark method proved more favorable. Tentative results from these first series of tests point to a safe upper limit for hydrocarbon film thickness greater than the 4000 microgramssq ft. A program was initiated for determining the filtration characteristics of solid CO2 from liquid oxygen. A system of liquefaction, filtration, and analysis of LOX was set up and test runs were started. The data show an apparent effect of the Reynolds Number effectively - liquid velocity of the liquid at the surface of the filtering medium. The concentration of the CO2 in the filtrate remains in the filtrate. This amount, approximately the solubility limit, will precipitate out of solution as the LOX is handled further or vaporized while in storage.
