1.Supercritical carbon dioxide.
It is a fluid state of carbon dioxide where
it is held above its critical temperature
and critical pressure.
Carbon dioxide usually behaves as a gas in
air at standard temperature and pressure
(STP), or as a solid called dry ice when
frozen.
It behaves as a supercritical fluid above its
critical temperature (304.25 K) and critical
pressure (72.9 atm ).

15. BCM 501 24/11/2014

USES
 In laboratories, supercritical carbon dioxide is used as an
extraction solvent.
Ex: In determination of total recoverable
hydrocarbons from soils, sediments, fly-ash, and other
media.

16.  Supercritical carbon dioxide is used to remove
organichloride pesticides from agricultural crops
without adulterating the desired constituents
from the plant matter in the herbal supplement
industry (Department of Pharmaceutical Analysis,
Shenyang Pharmaceutical University, Shenyang
110016, China).
Ex: DDT, Dicofol, Aldrin

(the height from the
turbines in the
powerplant to the water
surface) created by the
dam. The greater the
flow and head, the more
electricity is produced.
BCM 501 24/11/2014
32

33. WAVE POWER/TIDAL POWER
 Waves are generated by the
wind as it blows across the sea
surface. Energy is transferred
from the wind to the waves.
