At the present time, there is no practiced method of
extracting the water found in the industrial plants. Some work has been
done on using mechanical heat rejection to condense water vapor. Such
systems would require massive and expensive heat rejection equipment,
would be severely limited by high ambient temperatures, and would result
in decreased gas turbine performance.
Absorption system is applied where gas mixture is mixed with a liquid
for preferentially dissolving components of gas. It provides a solution
in form of liquid. It provides tested solutions for solute removal.
Absorption systems are more complex than conventional air conditioning,
but they offer a potential increase in efficiency if high temperature
waste heat is available.
The development of a liquid absorption system to reduce power plant
water consumption through flue gas recovery is founded on commercial
process technology currently used for industrial dehumidification
applications, such as natural gas dehumidification.
This new application for this technology represents significant
scientific/technological advancements in several areas:
- The desiccant absorber-contacting process must be scaled up from
its relatively small commercial basis to the very large volumetric
flow rates of power plant flue gases to result in economically
acceptable equipment.
- The dehumidification process must be properly integrated with
available low-grade heat sources and cooling sources in the power
plant to maintain acceptable power plant thermal efficiency and to
result in economic feasibility.
