   More like "latent heat of vaporization", especially for water vapor.  You   
   don't care about the gas removed, and what its condition is, only that it be   
   vented outside.  But you need to be sure the "treated mass" is kept warm, to   
   keep the offgassing rate    
   up.   
      
   Now you need to consider what you allow back in as you relieve the vacuum.    
   I'd recommend a low output ozone generator, such as you might bubble into a   
   glass of water.  But not required, could be the headspace of a vinegar bottle,   
   if you can stand that    
   smell any better.

   Consider that you have a sponge, with soap in it.  You want to get "all" the   
   soap out.  If you just squeeze it, you'll get a lot out.  But you will get   
   more out, and faster, if you allow fresh water in, and repeat a few times.    
   Same with this setup.
