GAS-L: Re: Evaporative Cooling for Biomass Drying?

["Harry W. Parker" <MIHWP@TTACS.TTU.EDU>]

The energy cost to produce the vacuum to dry the biomass for fuel would
be excessive.  In addition, you still have to supply about 1000 BTU/lb
water evaporated.  Yes the biomass would have to be heated.

Warm vegetables fresh from the fields, such as lettuce,  have been
chilled before shipping by pulling a vacuum on them to evaporate a small
amount of water.

ANOTHER TOPIC --  Our Texas Tech ChE dept policies/goals have changed
and so I am probably not going to have summer salary this summer. For
that reason,  I would be pleased to consider professional engineering
consulting activities for some of you all this summer.  Please contact
me directly at H.Parker@ttu.edu.
