Global Earth Warming is considered as one of the most dangerous
environmental problem that the World is suffering from . Some
observed changes are associated with the impact of Global Earth
Warming on our planet such as ; elevated temperature of the
biosphere, melting of polar ice, flooding, desertification, stress and
death of vegetation and migration of animals, shift in ranges of plant
and animal species, the increase of natural disasters ; earthquakes,
tsunami, flooding, and certain coastal areas will be exposed to
increasing risks such as coastal erosion due to sea-level rise resulting
in the disappearance of most of the coastal major cities, the expected
severe shortage of fresh water supplies and migration of disease
vectors.
It is undoubted that one of the main cause of Global Earth Warming
is the increase of carbon dioxide gas emission , resulted mostly from
the consumption of gaseous, liquid, or solid fossil fuels and burning
such fuels as a conventional sources of energy generation all over the
world, especially in the industrial and civilized countries.

There are several methods aimed to reduce or eliminate carbon
dioxide gas as follow:
1- Reduce the consumption of fossil fuels, which will seriously affect
the world economics.
2- Deviation to the non-conventional energy resources such as; solar
energy, wind energy, tidewater energy, earth geothermal energy,
….etc., which still highly expensive sources of energy when

compared to the cost-effective fossil fuels energy.
3- The absorption of carbon dioxide gas in chemical solutions such as
mono-ethyl amine and di-ethyl amine followed by stripping the
carbon dioxide gas from the solution and liquefy the gas by cooling
under high pressure. The liquefied carbon dioxide gas is then
pumped through a high pressure pipelines network may reach to
Tens of kilometers to be injected in geological special under-
ground
Stores far from the ground level or sea bottom level by a depth
that
Could reach 10 kilometers. It could also be injected in the old and
non-productive oil-wells and coal mines.
4- The adsorption of carbon dioxide gas onto metallic oxides such as
magnesium oxide and calcium oxide by allowing the favorite
Reaction conditions of temperature and the suitable contact time
For each reaction to produce landfill products.
5- The absorption of carbon dioxide gas in alkaline solutions such as
sodium hydroxide under pressure to produce sodium carbonate
which has different industrial uses.
The 5 Drawbacks of the Applied Technologies to
Reduce or Eliminate Carbon Dioxide Gas
1- The reduction in the consumption of fossil fuels, will seriously
Affect the world economics and most of the industrial countries did
not adopt it to realize the required success of most of the
International conventions and conferences negotiating the Global
Earth Warming Mitigation.
2- Non-conventional energy resources such as; solar energy, wind
Energy, tidewater energy, earth geothermal energy,..etc, is
still highly expensive sources ; when compared to the cost-
effective Fossil fuels energy.
3- The absorption of carbon dioxide gas in chemical solutions such as
mono-ethyl amine and di-ethyl amine followed by stripping the

3. Prof. Dr. Gamil Radwan IERC 77 GGlloobbaall EEaarrtthh WWaarrmmiinngg MMiittiiggaattiioonn

Carbon dioxide gas from the solution and liquefy the gas by
cooling under high pressure. The liquefied carbon dioxide gas
is then pumped through a high pressure pipelines network that
could reach tens of kilometers to be injected in geological special
under-ground stores far from the ground level or sea bottom level
by a depth that could reach to 10 kilometers. It could also be
injected in the old and non-produced oil-wells and coal mines which
requires expensive industrial technology. Moreover this technology
did not eliminate the carbon dioxide gas, but allows the injection,
storing and the accumulation of the carbon dioxide gas inside the
earth. Carbon dioxide gas is an acidic gas which injected, stored and
accumulated inside the earth under high pressure and at high
temperature. There are no reliable studies that can predict the
dangerous environmental effects of carbon dioxide gas on the long
run on the geological structures of the earth in such carbon dioxide
gas geological stores.
4- The adsorption of carbon dioxide gas onto metallic oxides such as
magnesium oxide and calcium oxide by allowing the favorite reaction
conditions of temperature and the suitable contact time for each
reaction to produce landfill products will not eliminate the carbon
dioxide gas but the carbonate products will accumulate inside the
earth.
5- The absorption of carbon dioxide gas in alkaline solutions such as
sodium hydroxide under pressure to produce sodium carbonate,
which has different industrial uses, will not eliminate thousand
million tons of the carbon dioxide gas annually emitted from the
world. The produced sodium carbonate is of limited use and the
excess amount may be subjected to landfill which may cause an
environmental problems in the future. .

This invention Adopt the following topics:
Eliminate the carbon dioxide gas without injection, storing,
or accumulation of the carbon dioxide gas inside earth as
previously mentioned .
Minimize the high cost of absorption of carbon dioxide gas
in chemical solutions such as mono-ethyl amine and di-ethyl
amine followed by stripping the carbon dioxide gas from the
solution and liquefy the gas by cooling under high pressure.
The liquefied carbon dioxide gas is then pumped through a
high pressure pipelines network may reach to tens of
kilometers to be injected in geological special under-ground
stores far from the ground level or sea bottom level by a
depth may reach to 10 kilometers or also may be injected in
the old and non-productive oil-wells and coal mines which is
very
Expensive industrial technology.
Enrich the environment with Oxygen gas, as one of the
products accompanying the complete elimination of the
carbon dioxide gas.
This invention will realize the
complete elimination of carbon
dioxide gas and will effectively
participate in the Mitigation of
Global Earth Warming.

This invention, IERC 77, is prepared from 77
chemical compounds. The compounds of IERC 77
are mixed thoroughly and added during agitation to
distilled water at a temperature not less than 25o
C
and not more than 35o
C.
The resulting solution combines with carbon dioxide
CO2 gas.
More than 95% of the carbon dioxide CO2 gas will be
removed and the products are only Oxygen gas O2
and Nitrogen N2.
Moreover the resulting solution will continue
reacting with Carbon dioxide to produce Oxygen gas
O2 and Nitrogen gas N2 when a make-up solution is
added.
In case of continuous operation of the reaction when
carbon dioxide gas passing through an absorption
tower , each 4 kilogram of carbon dioxide gas will
produce 1.1 kilogram of oxygen gas.
IERC 77is the patent which will
effectively participate in the
Mitigation of Global Earth Warming.
