Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If particles are not removed from the gas mixture before entering the adsorber, then the system structure remains simple, but the adsorber material degrades and clogs, reducing service life and efficiency
Solution Approach 1:
The electrostatic separator is positioned upstream of the adsorber to remove particles from the gas mixture before the gas enters the adsorber. This preliminary particle removal prevents degradation and clogging of the adsorber material, extending its service life and maintaining efficiency without requiring complex downstream filtration systems.
Solution Approach 2:
The electrostatic separator acts as an intermediary device between the gas mixture source and the adsorber. It uses electrostatic fields to charge and collect particles, serving as a protective barrier that prevents harmful particles from reaching the adsorber material while allowing the gas to pass through to the adsorber.
2Productivity
If large volumes of air are processed through the adsorber, then CO2 capture capacity increases, but particle accumulation accelerates, reducing operational efficiency
Solution Approach 1:
By implementing the electrostatic separator upstream, particles are removed from large volumes of air before they can accumulate in the adsorber. This allows the system to maintain high CO2 capture capacity while preventing the particle accumulation that would otherwise reduce operational efficiency.
3Adaptability or versatility
If the adsorber is exposed to high particulate load air, then the system can operate in adverse environments, but the adsorber material degrades faster
Solution Approach 1:
The electrostatic separator serves as a protective intermediary that enables the adsorber to operate in adverse environments with high particulate loads. By removing particles upstream, the adsorber is protected from degradation while the system maintains its ability to capture CO2 from challenging air sources such as desert or offshore locations.
