Hello all,
I have been curious about what can be used for pressurizing gasses for liquid
oxygen. The only two contenders I ever hear about are helium and nitrogen. Each
if these seems to have its problems. Helium is quite expensive and rare while
nitrogen will readily dissolve in lox. I'm having some trouble finding what is
and isn't soluble in lox but I would imagine that using gox could be a
solution. Obviously high pressure gox introduces some hazards but other
industries like scuba diving use it successfully. Are hazards the only reason
it is not widely used. What about other less expensive gasses like co2. Any
insights would be very helpful.
Thank you,
Zachary Martinez
