Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In gas transfer processing methods, it is challenging to maintain a large gas/liquid ratio within fine flow paths, hindering the efficient absorption and release of gases, as the coexistence of liquid and gas at such ratios is difficult in restricted spaces, leading to inadequate gas transfer.
Innovation Solution
A component transfer processing method and device that utilize a flow-path structure with fine flow paths, a separation portion, and a recirculation line to circulate absorption liquid, allowing it to repeatedly flow through the paths, promoting gas absorption and release by maintaining contact between the liquid and gas, even at large gas/liquid ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large gas/liquid ratio is used to achieve sufficient gas absorption or release, then the transfer efficiency of target component is improved, but it becomes difficult to maintain adequate two-phase flow in fine flow paths
Solution Approach 1:
The system segments the gas-liquid separation process from the fine flow path by introducing a separation chamber. The fine flow path handles liquid flow with high surface area, while the separation chamber handles gas-liquid separation, allowing each component to function optimally without compromising the other.
Solution Approach 2:
The invention transitions from a single-dimension fine flow path to a multi-dimensional system by adding a separation chamber dimension. This allows the gas-liquid ratio to be increased in the separation chamber without constraining the fine flow path geometry, resolving the contradiction between high gas/liquid ratio and adequate two-phase flow.
2Productivity
If absorption liquid is circulated repeatedly through fine flow paths, then gas absorption and release are promoted, but the space requirement and device complexity increase
Solution Approach 1:
The invention merges the separation function with the circulation system by designing the separation chamber as an integral part of the circulation loop. The absorption liquid flows from the fine flow path into the separation chamber, then returns to the fine flow path through the circulation pump, combining separation and circulation functions in a unified system.
Solution Approach 2:
The separation chamber serves multiple functions: it separates gas from liquid, acts as a reservoir for the circulation pump, and provides a transition zone for the absorption liquid before re-entry into the fine flow path. This multi-functionality reduces overall device complexity while maintaining high gas absorption and release efficiency.

Function Achieved in This Case
This approach enhances the transfer efficiency of target components into and out of the absorption liquid, improving the absorption and release processes by allowing repeated circulation of the absorption liquid through fine flow paths, even when adequate two-phase flow cannot be formed at large gas/liquid ratios.

AI summary
A gas transfer processing method includes: transferring gas to an inside or an outside of an absorption liquid within respective processing flow paths while circulating the absorption liquid through the respective processing flow paths; after the gas transferring, separating a mixed fluid including the absorption liquid discharged from outlets of the respective processing flow paths and gas by respective separation headers into the absorption liquid and the gas; and circulating the absorption liquid separated in the separating by returning the separated absorption liquid from the separation headers to inlets of the respective processing flow paths through respective recirculation lines, thus introducing the absorption liquid to the respective processing flow paths. The process promotes transfer of a target component to an absorption liquid, while enabling execution of a component transfer process by compact equipment.
