Abstract:
A method for concentrating a dilute rocket or laser fuel solution comprising:(a) introducing a working fluid into an apparatus comprising:a fluid dryer;a pump for compressing and moving the working fluid through the fluid dryer;a mass transfer device in fluid communication with the fluid dryer; anda heating source which is in contact with at least a portion of the mass transfer device;(b) operating the pump to compress the working fluid;(c) moving the working fluid into the fluid dryer;(d) operating the fluid dryer to remove water and/or water vapor from the working fluid to yield a low dewpoint working fluid;(e) moving the low dewpoint working fluid into the mass transfer device; and(f) contacting the low dewpoint working fluid with the dilute rocket or laser fuel solution in the mass transfer device to remove a diluent yielding a concentrated rocket or laser fuel solution.
