Re: [PSUBS-MAILIST] Methane scrubber



Hi Warren,

thanks for the reply.  I'm just researching submarine life support requirements at present.  I had thought one of the list members had mentioned this as areq for their sub (multiday missions).

In my research i have been hitting NASA sites pretty heavily - especially those related to long mission closed system life support (eg the mars mission), and it was certainly an issue for them  Flatulence may not be a problem (unless i had a lot of vegetarian passengers hahah), and this is one place i am seeking advice.  is it an issue, or at what mission length does it need to be factored in.

I am also interested in methane removal on another unrelated project and i thought this group may have some expertise.

thx in advance
peter

Methane? The scrubber technology I have played with
won't remove methane. Carbon Monoxide and Carbon
Dioxide. Why are you concerned about methane? :)
