Solution Overview

Problem

Existing mass transfer columns with dividing walls face challenges in controlling and adjusting the liquid split between the feed and draw-off sides, limiting operational flexibility and control in distillation processes.

Innovation Solution

A moveable liquid flow divider is positioned above the dividing wall to adjust the volumetric split of liquid between the sub-regions, allowing for increased operational flexibility by changing configurations to deliver varying liquid flows to the sub-regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed liquid flow divider is used in a mass transfer column with a dividing wall, then the structure is simple and easy to manufacture, but the operational flexibility and control ability for liquid split adjustment is limited

Engineering Contradiction:
Improveoperational flexibilityVSAvoidliquid flow divider structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The liquid flow divider is designed with moveable components that can be adjusted between different positions to change the volumetric split of liquid between sub-regions. This dynamic adjustment capability allows the system to adapt to varying operational requirements while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a moveable liquid flow divider is implemented to adjust liquid split, then operational flexibility is improved, but device complexity increases

Engineering Contradiction:
Improveliquid split controlVSAvoidliquid flow divider mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The liquid flow divider is segmented into multiple moveable portions that can be independently adjusted. This segmentation allows for precise control of liquid distribution to different sub-regions while keeping each individual moveable component relatively simple in design.

Inventive Principle:
Principle #1Segmentation

AI summary

A mass transfer column comprising: a shell (12); an open internal region (14) defined by said shell; and a mass transfer assembly (16) positioned in the open internal region (14), the mass transfer assembly (16) comprising: a dividing wall (18) forming first and second sub-regions; one or more zones of mass transfer structures positioned in the first and second sub-regions (22 and 24); and a liquid flow divider (48) positioned above the dividing wall (18) for delivering a volumetric split of liquid to the first and second sub-regions. The liquid flow divider (48) may comprise a moveable weir (68) or a valve (180) in order the change the ratio of liquid flow between the two sub-regions.
