Multi-Chamber Absorption Tower Layout for Height-Limited Gas Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Absorption towers for gas capturing are excessively tall due to a stacked arrangement, making them unsuitable for installations with height limitations such as buildings and ships.
Innovation Solution
The absorption tower is redesigned with compartments including a first, second, and third reaction chamber arranged orthogonally, utilizing conveying assemblies and heat exchangers to facilitate gas and liquid reactions across multiple chambers, reducing overall height and enhancing capture efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the absorption tower is arranged in a stacked manner to ensure full gas absorption, then the absorption efficiency is improved, but the tower height becomes excessively high (exceeding 40 meters)
Solution Approach 1:
The patent transforms the traditional vertical stacked arrangement of absorption sections into a horizontal multi-chamber configuration. The reaction chambers are arranged side-by-side in the horizontal direction rather than stacked vertically, fundamentally changing the spatial dimension of the absorption process. This allows multiple absorption stages to occur simultaneously in parallel chambers, achieving high absorption efficiency without increasing tower height.
Solution Approach 2:
The absorption tower is divided into multiple independent reaction chambers (first, second, and third reaction chambers) that are arranged horizontally. Each chamber functions as an independent absorption unit with its own gas-liquid contact mechanism. This segmentation allows the system to achieve the equivalent of multiple absorption stages in a compact horizontal layout, resolving the contradiction between absorption efficiency and tower height.
2Length of stationary object
If multiple reaction chambers are arranged horizontally to reduce height, then the tower height is reduced for height-constrained applications, but the system complexity increases with multiple conveying assemblies
Solution Approach 1:
The patent combines the liquid circulation and gas distribution functions into an integrated system. The conveying assemblies serve dual purposes: they convey reaction liquid between chambers while also facilitating heat exchange and mass transfer. This merging of functions reduces the number of separate components needed, thereby reducing system complexity despite the horizontal multi-chamber configuration.
Solution Approach 2:
The conveying assemblies are designed with multi-functionality, serving as both liquid transport mechanisms and heat exchange conduits. Each conveying assembly handles multiple tasks including liquid circulation, temperature control, and gas-liquid contact facilitation. This multi-functionality reduces the overall system complexity by eliminating the need for separate dedicated components for each function.
