The Atmospheric Protection System represents a complete paradigm shift in how we approach industrial emissions - from environmental liability to valuable resource.
Child Level (Ages 5–10)
Imagine our whole factory is inside a giant, clear bubble. The Atmospheric Protection System is like a giant vacuum cleaner for this bubble. It's always gently pulling air inwards, so no dust or smells can ever escape to the outside. It's like when you use a vacuum to clean up glitter. The vacuum sucks all the glitter up so it doesn't get all over the house. Our system does the same thing with any dust or gas inside the factory, saving all the valuable little bits so we can turn them into more useful things.
Layperson Level
How It Works: Plant-Wide Air Purification
The APS acts like a powerful kitchen hood vent, but for the entire facility. It constantly pulls air into a network of ducts from every area where dust or gas could potentially be released, purifying the air throughout the plant.
Negative Pressure Environment
This system creates a negative pressure environment inside the facility. This means that if there were ever a tiny leak, clean air would rush in from outside, rather than valuable process vapors escaping, ensuring containment and safety.
Resource Recovery
Unlike traditional methods that treat escaped vapors as waste, Carbotura sees them as lost resources. Our APS captures these vapors, cleans them thoroughly, and transforms them back into valuable products, closing the loop on emissions.
High School Level
The Atmospheric Protection System (APS) is an engineered safety and environmental control system designed to capture 100% of fugitive emissions. Its operation is based on maintaining a constant negative pressure within all processing buildings.
For a 400 TPD facility, the APS is designed to capture approximately 1,200 metric tons of fugitive organic compounds per year. Instead of venting these as a permitted emission, we re-process them.
This captured material is sent through an electromagnetic cracker and converted into additional Pristine Carbon, turning a potential environmental liability into a significant revenue stream.
Undergraduate Level
High Volumetric Flow Rate: 60,000 m³/hr
The Atmospheric Protection System (APS) efficiently handles a substantial volumetric flow rate, primarily consisting of air and nitrogen, which may contain trace concentrations of process gases. This high capacity ensures comprehensive capture across the facility.
Consistent Negative Pressure: -0.2 bar Differential
A key aspect of the APS design is the maintenance of a constant negative pressure differential of -0.2 bar throughout the entire facility. This critical design feature prevents any fugitive emissions from escaping into the environment, ensuring full containment.
1,200 Tons/Year of Captured Hydrocarbons
Unlike traditional linear economic models where permits might be obtained to release these as acceptable losses, the APS captures approximately 1,200 metric tons of fugitive hydrocarbons annually. These are then re-processed, preventing environmental release.
Annual Revenue Impact: $7.7 Million
The captured hydrocarbons are not merely contained; they are transformed into valuable synthetic graphite. This process yields an additional 2.8 metric tons per day of synthetic graphite, contributing a significant annual revenue of $7.7 million at $7,500 per ton.
The APS is a distributed vapor capture and processing system. Our circular manufacturing model treats fugitive volatile organic compounds (VOCs) as an uncaptured product stream rather than waste, reprocessing them into valuable synthetic graphite.
Graduate Level
Techno-Economic Assessment
Modeling the APS involves a complex techno-economic assessment. The Capital and Operational Expenditures (CapEx/OpEx) of the system are evaluated against the Net Present Value (NPV) of the recovered product stream.
Compliance vs. Yield
Traditional industrial facilities model fugitive emissions as a compliance cost (permitting fees, potential fines). Our model treats the APS as a yield-maximization unit with a quantifiable ROI.
Economic Viability
The economic viability is strong because the recovered hydrocarbons are of high quality. By re-introducing them into the main process, we increase the feedstock for our highest-value products (Pristine Carbon and Graphite) without increasing the raw MSW input, directly boosting the facility's overall profitability.
Specialist Level
Integrated Utility
The APS is designed as a fully integrated, plant-wide utility. The control system uses a Model Predictive Control (MPC) strategy.
Material Balance
The material balance of the captured fugitive stream is a non-trivial input to the overall plant simulation. The recovered hydrocarbons are routed back to the main process, which directly impacts the mass balance of the CRU and the final graphite yield.
Economic Feedback Loop
This creates a positive feedback loop in the economic model: the value of the recovered materials directly offsets the operational cost of the APS, making the "zero emissions" goal not just an environmental mandate, but a financially optimized strategy.
Research Frontier
Decentralized Sensing
The research frontier focuses on developing low-cost, solid-state sensors for widespread deployment at every emission point. This aims to create a high-resolution, real-time "map" of fugitive emissions, moving beyond reliance on a few complex analyzers.
Autonomous AI Control
Could a decentralized AI system be implemented, where local controllers at each collection hood make autonomous adjustments to optimize capture? These controllers would communicate to maintain overall system stability, enhancing efficiency and reliability.
Predictive Machine Learning
Current experiments develop machine learning models to predict fugitive emissions using process equipment data, such as motor vibration and seal temperature. This enables the APS to react to potential leaks proactively, even before traditional gas sensors detect them.
Simulation & Modeling Accuracy
The APS is modeled using a comprehensive Computational Fluid Dynamics (CFD) simulation. This model includes the full 3D geometry of the facility buildings, all major equipment, and the entire network of collection hoods and ducting.
By calibrating this model with empirical data from smoke tests and anemometer readings in our pilot facilities, we can achieve a predictive accuracy for airflow and pressure distribution that is within 95-98% of real-world performance. This high degree of accuracy is essential for ensuring that the final, as-built system meets all safety and environmental requirements for complete emissions capture.
