Abstract
A system and method for the co-production of a densified, liquid oxidant and a densified liquid methane fuel to a space vehicle launch facility is provided. In one embodiment, a low pressure gaseous oxygen stream is piped from a nearby air separation unit to the space vehicle launch facility where it is then liquefied and densified in a two-stage, integrated liquefaction/densification system that also densifies a source of liquid methane. In an alternate embodiment, a liquid oxygen stream produced at an air separation unit is densified in a two-stage, integrated densification system configured to densify both the liquid oxygen as well a source of liquid methane at or near the air separation unit with the resulting densified liquid products transported via truck/trailer to a nearby space vehicle launch facility.
