Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorption devices have poor contact efficiency between the absorbing liquid and gas, resulting in low absorption rates and difficulty in increasing the absorption amount per unit volume of the absorbing liquid.
Innovation Solution
The method involves circulating a gas and an absorbing liquid in a minute passage while supplying a third fluid to increase pressure, enhancing gas-liquid contact and absorption efficiency, and using a device with specific fluid headers and passages to manage the circulation and pressure increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional absorption towers are used, then the structure is simple and easy to operate, but the contact efficiency between absorbing liquid and gas is poor, resulting in low absorption rate
Solution Approach 1:
The absorption device is segmented into multiple minute passages arranged in parallel, each providing intensive gas-liquid contact. This segmentation increases the total contact area and absorption rate while maintaining a relatively simple overall structure through modular arrangement
Solution Approach 2:
The invention transitions from conventional large-scale absorption towers to minute passages with micro-scale dimensions. This dimensional change enables significantly higher contact efficiency between gas and liquid phases while allowing compact device configuration
2Quantity of substance
If conventional absorption towers are used, then the device structure is simple, but the absorption amount per unit volume of absorbing liquid is low
Solution Approach 1:
Multiple minute passages are arranged in parallel to increase total absorption capacity. This segmentation allows the system to achieve high absorption amount per unit volume of liquid while maintaining a compact and relatively simple device structure through efficient spatial utilization
Solution Approach 2:
The invention changes the characteristic parameters of the absorption channels from conventional large dimensions to minute scale dimensions. This parameter change dramatically increases the surface area to volume ratio, enabling high absorption amount per unit volume of absorbing liquid
3Productivity
If pressure is increased in conventional absorption towers, then absorption rate may improve, but the structural requirements and operational complexity increase
Solution Approach 1:
The transition to minute passage scale enables effective pressure increase without requiring complex heavy-duty structures. The small dimensions allow standard pressure control equipment to effectively manage the system, maintaining ease of operation while improving absorption rate through enhanced contact under pressure

Implementation Method 1
a sub-circulation step for circulating a third fluid in the minute passage, thereby increasing a pressure inside of the minute passage
Implementation Method 2
a main circulation step for circulating, as a first fluid, a gas containing a component to be absorbed and an absorbing liquid as a second fluid in the minute passage, thereby absorbing the component to be absorbed in the gas by the absorbing liquid

AI summary
An absorption method includes: a step for preparing a minute passage; a main circulation step for circulating, in the minute passage, a gas as a first fluid containing a component to be absorbed and an absorbing liquid as a second fluid so that the component to be absorbed is absorbed from the gas into the absorbing liquid; and a sub-circulation step for circulating, while the gas and the absorbing liquid are circulated in the minute passage, a third fluid in the minute passage in order to raise the pressure inside the minute passage.
