Requirements

Main Content

Customer Requirements:

 1. Capture CO2 as efficiently as possible
• Capture the most amount of CO2 for the least amount of energy

2. Capture as much CO2 as possible
• Capture as much CO2 as possible from the air pulled through the reactor

3. Utilize Vacuum moisture swing
• Utilize Vacuum pressures that allow water to vaporize with minimal heating to allow for a more efficient moisture swing

4. Minimize water use
• Recycle as much water as possible through the system

5. Track the metrics of the apparatus as it runs
• Position various sensors in critical areas to record pressures, temperatures and evaporation rates

6. Variable flow rate, and pressure
• Allow variation in operational conditions to allow for testing and optimization of various structures

7. Maintain clean lab environment to protect experimental equipment
• Avoid any contaminants such as oil and dust from interfering with sensors, pumps and other equipment

8. Keep design compact
• The design must be a practical scale for small batch tests of experimental sorbents and fit within the available lab space.

9. Utilize existing common vacuum parts
• Majority of components should be selected from commercially available options to keep costs down, save time, and allow for future modifications or scaling.
