Project Name: Optimum use of Industrial Exhausts gases
Project Theme: Industry
Two main problems with petrol are:
1. It is non-renewable and will get exhausted very soon.
2. On burning petrol many harmful pollutants are released in the environment.
3. We need to find ways to reduce emission of carbon dioxide into atmosphere and a fuel which is renewable and causes no pollution that can replace petrol.
Principle: The model is designed to separate and purify carbon dioxide from the main exhaust(rich in carbon dioxide).The carbon dioxide is purified and separated by the amine scrubbing process and can be used in various industrial processes and can be used to generate an alternate for petrol.
Methodology:
1. Scrubber and separator are needed to separate and purify CO2 from exhaust.
2. A storage tank to collect pure CO2.
3. A bioreactor is needed to convert CO2 into a fuel (Isobutanol). This conversion is possible with use of electricity, water, and a genetically modified bacteria (Ralstonia Eutropha H16)
Apparatus:
1. Two large containers made of KALREZ material.
2. Monoethanolamine.
3. Glass bioreactor (with supply of electricity, water, and Ralstonia Eutropha H16).
4. Platinum mess as anode.
5. Anode surrounded by ceramic cup.
Process:
1. The main industrial exhaust pipe of the industry is connected with the scrubber in which a cool solution of monoethanolamine is present. The CO2 will be absorbed by amine solution and other gases will not react with it and other gases will be sent to the environment after pretreating. The solution left behind will be sent to the separator. The solution left behind will be sent to the separator and will be heated to significant temperature and pure co2 will be collected in the storage tank. From this storage tank it can be used for various purposes.
2. The pure CO2 will be sent to the bioreactor. Here a genetically modified bacteria Ralstonia Eutropha H16is present. This bacteria will inhale formate (HCOO- which willbe formed in the presence of electricity, water and CO2) and excrete Isobutanol as a waste product. This Isobutanol can be used as an alternate for petrol without any change in the current petrol engines.
