FOREWARD:

CO₂ is basically considered the most hazardous component to the very extinction of the earth. It is the main cause for GLOBAL WARMING, if this continues then there will be 2 Venus’ in the solar system. The basic objective here is to use CO₂ or extract and store it , so that it can be used as an alternative fuel . And since CO₂ is very dangerous to earth and the percentage of levels of CO₂ is rising, the need for balancing CO2 level in the atmosphere is much required.

INTRODUCTION:

The objectives are:

• To extract CO₂ from the atmosphere, without affecting the environment.
• To design a mechanism of extracting CO₂, effectively than other processes.
• To reduce green house effect.
• In turn global warming.
• Stepping stone or a basic unit for eco-friendly designs.

SCOPE:

Many research and developments are going on in this field to reduce CO₂ level in the atmosphere, and also to convert it into other useful forms of energy. So this device can be incorporated in those systems.

DEFINITIONS:

PERFORMANCE REQUIREMENTS:

This mechanism provides one of the better ways to extract CO₂ from the atmospheric air without affecting the ecosystem.

This is basically a static device. which works in the temperature range of 10 deg to 50 deg Celsius. And it is independent of humidity. This device can be built of many sizes depending upon the percentage of CO₂ required for different applications. The active material or the working substance used is AMINE along with water. Amine reacts with water to form (Amine-H₂O).

Amine + Water à (Amine-H₂O)

When air is blown through this solution, all other components of except CO₂ bubbles out and only CO₂ reacts to give (Amine –H₂CO₃ ) .

CO₂ + (Amine-H₂O) à (Amine-H₂CO₃)

The Amine that is used in this device costs around Rs 550/- for 250g. Though the cost is quite high compared to other alternate materials which are used to capture CO₂ like NaOH. But the main advantage of using Amine is that it can be reused or recycled for more than 5000 times.

(Amine-H₂CO₃) formed when heated to a temperature of 70 deg Celsius it gives Amine, water and carbon-di-oxide.

(Amine-H₂CO₃) à_heat Amine + H₂O +CO₂ ↑

This is how carbon-di-oxide can be extracted from the atmospheric air.

MANUFACTURE REQUIREMENTS:

This device will have 3 compartments, an air blower, a pump along with amine, water and atmospheric air. The first compartment will have 3 inlet valves, air blower is connected to one, one is at the top, to let in Amine and water and the third one is to refill the compartment with Amine and water, which is recycled. And 2 outlet valves, one for the components of air other than CO₂ to escape into the atmosphere and another one to send the (Amine-H₂CO₃) to the second compartment. In this air blower and side outlet valve is gang tuned such that as long as blower is on, valve should be closed and when blower stops then, after few seconds ( say 5s) the valve should open.

Second compartment comprises of an electric heater , temperature measuring device, 2 outlet valve ,one at the top to separate CO₂ from the solution and another one at the side, to pump back the Amine-water solution to the first compartment and 1 inlet valve to allow (Amine-H₂CO₃) into the second compartment . The electric heater, temperature measuring device, inlet and side outlet valve is gang tuned in such a way that at first inlet valve is open and it allows (Amine-H₂CO₃) to the compartment and outlet valve remain closed,as heater starts heating the solution inlet valve also closes

And when the temperature reaches 70deg CO₂ is liberated and it gets separated. As temperature reaches 72deg outlet valve opens , to which a pump is attached which pumps amine+water back into the first compartment. It reaches there by flowing in a pipe which is very good conductor of heat and it will be surrounded by a water jacket, which cools down the temperature of the working fluid to room temperature. Then cycle repeat.

Carbon-di-oxide which comes out of outlet valve is collected in the third compartment , which has an inlet and outlet valve. This outlet valve is connected to other system which uses CO₂ for various purposes.

ACCEPTANCE STANDARDS:

Every mechanism and product will be inspected prior to its assembly .The instrument or the product is designed in such a way that it accepts all the international standards and norms .There is no emission of harmful gases to the atmosphere and the product’s main motto is to maintain or to strike a balance between human beings and the environment .The mechanism and the product does not conflict with any of the existing patents.

DISPOSAL:

Since the working material that we are using is AMINE which can be recycled for more than 5000 times and other materials used are water and air which are the integral part of nature hence this process isn’t hazardous to environment. It is 100% eco friendly. After 2-3 years, if amine has to be changed, then you can remove the connection between the pump and the 2^nd compartment thus by doing this we can remove amine and water.

OPERATIONAL REQUIREMENTS:

During installation all the valves of both inlet and outlet valves of all 3 compartments

are connected properly. Heater, blower and pump are connected to ac power supply.

Using of this device is simple, switch on the power supply and turn on the blower, and switch it off after a minute then the process starts and carbon di oxide is extracted from the air.

Even if more amount of air is sent through the blower, then there is no harm as depending upon the amount of active substance, CO₂ reacts with amine-H₂O excess will be sent out along with other components of air.

Conserving the environment is the main objective of the product and hence it strives to provide an alternate and an ultimate answer for global warming concerns.
