Solution Overview
Problem
Existing acid gas adsorption devices using organic binders soluble in protic polar solvents face instability due to environmental factors like water vapor, leading to inconsistent carbon dioxide absorption performance.
Innovation Solution
An acid gas adsorption device utilizing an organic binder soluble in aprotic polar solvents and insoluble in protic polar solvents, combined with acid gas-adsorbable particles, forms a stable structure with a three-dimensional network or porous lamellar surface, maintaining adsorption ability despite environmental changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an organic binder soluble in protic polar solvent is used to bind acid gas-adsorbable particles, then the particles can be retained in a stable structure, but the structure changes under environmental influence (water vapor) leading to poor reliability
Solution Approach 1:
The patent changes the solubility parameter of the organic binder by selecting a binder soluble in aprotic polar solvents rather than protic polar solvents. This parameter change makes the binder resistant to water vapor and environmental moisture, preventing structural changes and maintaining stable adsorption performance under varying environmental conditions.
Solution Approach 2:
The patent creates a composite material system consisting of acid gas-adsorbable particles combined with an organic binder having specific solubility characteristics. This composite structure leverages the adsorption capability of particles while the binder provides structural stability and environmental resistance, achieving both high performance and reliability.
2Reliability
If an organic binder soluble in aprotic polar solvent is used, then resistance to water and environmental factors is improved, but the binder must be dissolved in a specific solvent system requiring precise control
Solution Approach 1:
The aprotic polar solvent acts as an intermediary medium that enables the organic binder to be processed and applied to the acid gas-adsorbable particles. This intermediary allows for stable dispersion and bonding while maintaining water resistance, and can be removed or evaporated after application, simplifying the manufacturing process.
