Re: [PSUBS-MAILIST] Methane scrubber
I'll do some further research. There are a couple
of chemists where I work, and I'll ask them too. I
can't imagine methane would be a concern for normal
PSUB use, but for heavy use perhaps. Anyway, it is an
interesting problem. I have actually been spending my
time going over biological air recycling because I am
very interested in under-sea habitats.
