Drawer-Type Solvent Purification Modules for Continuous Carbon Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-combustion carbon capture devices face issues with heat-stable salts, high molecular weight degradation products, and other pollutants leading to corrosion, reduced productivity, and inefficient purification due to the limitations of activated carbon filters, which cannot completely remove these impurities and require complex and disruptive maintenance.
Innovation Solution
A drawer-type carbon capture solvent purification and recovery device with a Ferris wheel-type mounting frame allows for flexible and adjustable purification, enabling the rotation of purification modules between filtration and regeneration regions, facilitating easy replacement and regeneration of packing layers, and incorporating conductivity meters and differential pressure gauges for monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If activated carbon filter is used to purify the regenerated lean liquid, then impurities are adsorbed in the pore of activated carbon, but the activated carbon filter cannot completely remove heat-stable salt, high molecular weight degradation product, metal ion and other pollutants
Solution Approach 1:
The purification system is divided into multiple independent purification modules that can be selectively configured. Each module contains specific packing materials targeted at different impurity types, allowing comprehensive purification that exceeds the capability of a single activated carbon filter.
Solution Approach 2:
The system employs composite packing materials with different functional properties within the purification modules. Different packing layers target specific impurities (heat-stable salts, degradation products, metal ions), creating a composite purification approach that completely removes all pollutant types.
2Reliability
If traditional activated carbon filter packing is replaced when close to penetration, then purification function is maintained, but machine shutdown is required and operation efficiency is affected
Solution Approach 1:
The purification modules are designed to be dynamically replaceable and reconfigurable during operation. The modular architecture allows selective module replacement without shutting down the entire system, maintaining continuous purification function while minimizing operational disruption.
Solution Approach 2:
The filtration system is segmented into multiple independent modules rather than a single integrated filter. This allows individual modules to be replaced or regenerated independently, enabling continuous operation where one module can be serviced while others remain operational.
3Reliability
If packing layer is replaced in traditional activated carbon filter, then purification capacity is restored, but all packings must be taken out for replacement which increases workload
Solution Approach 1:
The packing is organized into separate, accessible modules rather than a monolithic structure. This segmentation allows targeted replacement of only the worn modules without handling the entire packing bed, significantly reducing maintenance workload and operational complexity.
Solution Approach 2:
Individual purification modules can be extracted and replaced independently from the system. This extraction capability allows operators to remove only the necessary components for maintenance without disrupting the entire purification system, reducing overall maintenance workload.
4Reliability
If multiple purification technologies are combined, then purification level is improved, but device complexity increases
Solution Approach 1:
The complex purification system is segmented into standardized, interchangeable modules. Each module implements specific purification functions, and the modular design allows these functions to be combined in a systematic way that manages complexity through standardization rather than customization.
Solution Approach 2:
The purification modules are designed with universal interfaces and standardized configurations that allow the same module type to serve multiple purification functions or be arranged in different configurations. This universality simplifies the system despite the combination of multiple purification technologies.

AI summary
Provided are a drawer-type carbon capture solvent purification and recovery device and method. The recovery device includes a support, a mounting frame and a purification module, the purification module is connected in an insertable manner to the mounting frame along the outer periphery of the mounting frame at equal intervals, and two adjacent purification modules are communicated with each other. The left half of the mounting frame forms a purification region, and the right half of the mounting frame forms a regeneration region. A liquid to be filtered sequentially flows through all purification modules in the purification region from top to bottom and then is discharged from a liquid outlet pipe.
