Process Captured Gases

Process Captured Gases

Implementing a system to scrub, split, and purify gases from emissions to 99.99% purity is a highly advanced and intricate process, but it can be very effective for reducing environmental impact and recovering valuable gases. Here's how this would be operationalized:

1. Gas Scrubbing and Pre-Treatment

  • Particulate Removal: The first step involves using filters or cyclonic separators to remove all particulate matter from the gas stream. This ensures that the subsequent gas processing equipment operates efficiently and prevents any solid pollutants from being released.
  • Scrubber System: A wet or dry scrubber system is deployed to remove harmful gases such as sulfur oxides (SOx) and nitrogen oxides (NOx). This step chemically neutralizes or absorbs these contaminants, preparing the gas stream for further processing.

2. Gas Splitting and Purification

  • Gas Separation: The scrubbed gas mixture is then sent to a gas separation system. Techniques such as cryogenic distillation, pressure swing adsorption (PSA), or membrane separation are used to split the gas into its individual components, such as carbon dioxide (CO2), methane (CH4), nitrogen (N2), and others.
  • Purity Enhancement: Each separated gas is further purified using advanced techniques, like:
    • Pressure Swing Adsorption (PSA): Used for gases like hydrogen or nitrogen, PSA systems can achieve high purity levels by selectively adsorbing specific gases under pressure and releasing them when the pressure is reduced.
    • Cryogenic Purification: Particularly useful for oxygen or noble gases, this method cools the gas until it liquefies, allowing impurities to be separated.

3. Mass Spectrometry for Purity Control

  • Real-Time Monitoring: Mass spectrometry is used to analyze the composition of each purified gas stream. This ensures that the purity level reaches 99.99% and allows for continuous monitoring and adjustment. ESCo2 converter utilises the more advance technology of quantum sensing and AI machine learning to optimise the processes at atomic levels. 
  • Quality Assurance: Any deviation from the desired purity level triggers automatic adjustments in the system or recycles the gas for further purification.

4. Emission of Cleaned Air

  • Final Filtration: Before releasing any remaining gases into the atmosphere, the air is passed through a final filtration system to ensure no residual particulate matter or harmful compounds are present.
  • Environmental Compliance: The purified air stream must meet or exceed regulatory standards for air quality, ensuring the process is environmentally friendly.

Benefits of This Approach

  1. High Purity Levels: Achieving 99.99% purity ensures the recovery of valuable gases for resale or reuse in industrial processes.
  2. Zero Particle Emissions: The removal of particulate matter guarantees that no solid pollutants are released into the air, significantly reducing environmental impact.
  3. Economic Value: By recovering and purifying individual gases, the system can generate additional revenue streams, such as selling pure carbon dioxide or methane.
  4. Regulatory Compliance: The process helps the plant comply with stringent emissions regulations and potentially qualify for environmental credits or incentives.
