DESALINATION PLANT NEAR OCEANS


We all know there is a huge shortage of drinking water across the world. In fact all major countries are facing the water crisis. People across the world trying new measures to save precious water like rain harvesting, formation of new ponds etc. This is for saving the water for future requirement.

However, as well all know that 75% portion of our earth is covered by Oceans which contains Saline water. But we cannot use this water for our daily purposes like drinking, washing etc.

But why we can't use this water?

We can easily process this salty water so that the salt content present in it can be removed and used further for domestic purposes.

We have the capability to install "Desalination Plants" near the oceans as water is easily available at free of cost.

However operational cost may be more but water problem may can easily be removed from the world if we can construct small sized plants near the shore.

EXTRACTION OF HYDROGEN FROM WATER



Development & modernization of any country is respectable but depletion of all its resources by means of progress is not favorable which is very common these days.

Every nation is trying to build its value and exhausting its resources like petrol, diesel, gasoline etc. As a matter of fact, in coming years all the natural resources tends to over, then what?

For this we have to think about some alternate option so as to avoid the situation of emptiness. That alternate option for fuel can be HYDROGEN.

As, Calorific Value of Hydrogen is maximum within common fuels. Below is the list which shows the comparison of Hydrogen with other fuels.

Fuel
Calorific Value
kJ/kg
Butane
49510
Charcoal
29600
Diesel fuel
44800
Gasoline
47300
Hydrogen
141790
Kerosene
46200
Methane
55530
Methanol
23000
Oil, heavy fuel
43000
Petrol
48000
Petroleum
43000
Propane
50350

So, why can’t we do the following:-
1.) Extract the Hydrogen gas from the easily abundant water (from ocean) and use it further as a fuel?

By means of it, we can use the Hydrogen gas as fuel and inbuilt some technology for hydrogen based engines.

CONVERSION OF POLYTHENE IN TO PETROL?



Being a science student and living in an gadget world, many things come into my minds which are quite basic but it may prove innovative if applied in a particular direction.

One of those innovative idea is “Conversion of Polythene in to Petrol”

Basically both Polythene and Petrol are from the same Hydrocarbon family with Hydrogen & Carbon as its main constituents.


DESCRIPTION
CHEMICAL FORMULA
Polythene
(C2H4)nH2
Petrol
CnH2n+2
Where “C” stands for Carbon and “H” stands for Hydrogen.


My mind strikes by concluding the fact that, if they both are of same family, why can’t we convert the waste polythene into petrol? We are living in a very hi-tech, scientific and over advanced world, but yet we have not developed such technique which recycles the waste material (polythene) in to a useful product (petrol).

As per internet sources, Polyethylene (plastic pipes etc.) demand in India grew from 1946 KTA in 2006 to 3479 KTA in 2012 and domestic production (polythene bags) grew at a slower rate, increasing from 1935 KT in 2006 to only 2332 KT in 2012. 

However, approximately 5.6 million tons per annum (TPA) of plastic waste is generated in country, which is about 15342 tons per day (TPD).

In short,
Domestic Polythene production per year = 23.22 x 107 Kgs
Waste due to use of Domestic Polythene per year = 560 x 107 Kgs

It shows that, there is a large amount of polythene waste available, which can be converted to produce petroleum products, which can be further used as a fuel to produce energy.
