The present invention provides compact adsorption systems that are capable of
rapid temperature swings and rapid cycling. Novel methods of thermal swing adsorption
and thermally-enhanced pressure swing adsorption are also described. In some aspects
of the invention, a gas is passed through the adsorbent thus allowing heat exchangers
to be very close to all portions of the adsorbent and utilize less space. In another
aspect, the adsorption media is selectively heated, thus reducing energy costs.
Methods and systems for gas adsorption/desorption having improved energy efficiency
with capability of short cycle times are also described. Advantages of the invention
include the ability to use (typically) 30-100 times less adsorbent compared to
conventional systems.
