Fill'er up -- Where did the RP-1, LOX 7 H2 come from?
The otherwise exceptional "Moonport" does not discuss
where the massive quantities of propellants needed came from. I infer there were no plants built on-site, but it had to come from somewhere, by rail I'd assume. Any suggestions as to where to look for details? -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |

The RP-1 was provided by the Moonshine Growers Association of Georgia as a contribution to the effort to beat the Russians and preserve the Moonshine industry for mankind by preventing the commies from taking over and forcing them to grow Vodka instead. Thank you, RJ...er, OM. I'm sure that's an answer some of our more squirrelly regulars can comprehend and endorse. Now I'll do my Verne-answer: LOX is manufactured by fractional cryogenic distillation of air, raw materials being air and electricity to run compressors and heat exchangers. There's a plant in nearby Mims; delivery is by insulated tank truck now, might have been by rail then. It's common to see trucks of LOX and LN2 and other cryogenic gases in most big cities. LH2 is manufactured in Louisana or thereabouts by steam reduction of natural gas; liquification is similar to LOX production but more energy-intensive. Delivery by (highly) insulated tank truck. Petroleum industry uses LOTS of hydrogen, much more than NASA, but generally in gaseous form I think. RP-1 is manufactured by the petroleum industry to specification just like regular kerosene (fractional distillation of petroleum), but with additional steps to provide purity (specific HC molecular chains and very low contaminants). Delivery probably by truck or by rail from where-ever. Storage of cryogens is obviously short-term, so production is more or less continuous and delivered as needed. RP-1 is probably much more long-term storable. --Damon |

Sure it is, but a truck or two won't do the job we're discussing. But then, an underground pipeline of any length would be ...interesting.... A railcar seems to hold about 10,000 gallons...

RP-1 is manufactured by the petroleum industry to specification just like regular kerosene (fractional distillation of petroleum), I agree that kerosene is easy...by comparison.

A railcar seems to hold about 10,000 gallons... Yeah, it's a fleet of tank trucks, both for LOX and LH2. I watched one campaign in late 2000 where truck after truck trundled down to Titusville and over to the Shuttle launch complex from the Mims facility. Might have been ten or more trucks hauling oxidizer, but still only a small part of the total industry fleet of cryo tanker trucks. --Damon |
