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 ).


Слайд 15
24/11/2014
BCM 501

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.

Слайд 16Supercritical 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
Supercritical carbon dioxide can also be used as a more environmentally friendly solvent for dry cleaning.

Слайд 18DFE(Design for environment)
EPA's Design for the Environment (DfE) works in partnership

with industry, environmental groups, and academia to reduce risk to people and the environment by finding ways to prevent pollution.
DfE has evaluated human health and environmental concerns associated with traditional and alternative chemicals and processes in a range of industries.

24/11/2014

BCM 501


Слайд 19What Does the DFE Label Mean?
EPA allows safer products to carry

the Design for the Environment (DfE) label. This label enables consumers to quickly identify and choose products that are safer for them, their families, and the environment.

When you see the DfE logo on a product it means that the DfE scientific review team has screened each ingredient for potential human health and environmental effects .

BCM 501


Слайд 26
In 1955 the first solar car invented was a tiny 15-inch

vehicle created by William G. Cobb of General Motors Called the Sunmobile.
Samsung India launched the first solar-powered phone, the Solar Guru 1107, which allows users to charge the phone anywhere the sun is shining.
1 hour of solar charging gives you 5 to 10 minutes of time to talk.

SOLAR ROAD
Netherlands on

12/11/2014 unveiled the world's first solar bike path, a revolutionary project to harvest the sun's energy that could eventually also be used on roads.
The so-called "SolarRoad" bike path is made of concrete modules each measuring 2.5 by 3.5 metres embedded with solar panels covered in tempered glass.

Слайд 29WIND POWER
Wind turbines converts the kinetic energy in the wind into

mechanical power that runs a generator to produce clean electricity.
wind energy contributes only 1% of global electricity generation.

24/11/2014

BCM 501


Слайд 30
In 1920 Betz showed that the maximum power that may be

a captured by a wind machine is 59.3% of the incoming energy in the wind.
The amount of electricity produced by one turbine depends on its size and quality of wind resource.
A typical 2-megawatt turbine, when placed in an appropriate wind resource, can provide enough emissions-free electricity to power about 500 average homes for a full year.

24/11/2014

BCM 501


Слайд 31WATER POWER
Hydroelectricity:-
Hydroelectricity uses the energy of running water to make Electrical

energy.
Hydro-electric stations are built where there is Running water is stored.

24/11/2014

BCM 501


Слайд 32
The amount of electricity generated is determined by the volume of

water and the amount of "head" (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.

24/11/2014

BCM 501


Слайд 33Wave 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.
Wave energy has the potential to be one of the most eco friendly forms of electricity generation.
The first tidal power station was the Rance tidal power plant built over a period of 6 years from 1960 to 1966 at La Rance, France.

Слайд 34

The pelamis is an offshore wave energy converter that uses the

motion of waves to generate electricity.
The machine operates in water depths greater than 50m and is typically installed 2-10km from the coast.
On average one machine will provide sufficient power to meet the annual electricity demand of approximately 500 homes.

Pelamis wave energy converter


Слайд 35GEOTHERMAL ENERGY
The term Geothermal originates from two Greek words 'GEO' and

'THERM'.
The Greek word ‘geo’ means the earth and ‘therm’ means heat from the earth.
Geothermal energy is energy derived from the heat of the earth.
