Effective Utilization of Factory Smoke
A sustainable approach using catalytic separation and CO₂
reuse
Introduction
Factory smoke contains pollutants that harm the environment.
This project proposes a way to capture and reuse CO₂ from
factory emissions for useful purposes.
Smoke Composition & Catalytic Converter
Factory smoke contains CO₂, NOₓ, SO₂, and particulates. A
catalytic converter separates CO₂ selectively using a filter and
catalyst material that absorbs CO₂ more efficiently.
Channel 1 – Compost Acceleration
The separated CO₂ is diverted to composting chambers where it
enhances microbial activity, speeding up the decomposition
process and improving manure quality.
Channel 2 – Dry Ice Production
CO₂ from the catalytic converter enters a system to be
converted into dry ice for multiple uses including cooling and
fogging.
Dry Ice Production Process
Step-by-step transformation of CO₂ to dry ice:
Compression: Gaseous CO₂ is pressurized using industrial
compressors.
Liquefaction: Pressurized CO₂ is cooled to convert it into
liquid form.
Freezing: The liquid CO₂ is rapidly depressurized and
frozen into solid dry ice.
Environmental Benefits
The process reduces air pollution and repurposes CO₂. It
benefits agriculture, cold transport, and lowers industrial
carbon footprint.
Future Scope
This model can be applied to all manufacturing units to
promote clean, circular usage of emissions and meet
sustainability goals.
Conclusion
Factory emissions can become valuable resources when treated
with the right technology. This project shows how science can
lead to sustainable industry solutions.
