Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual flow trays are used to increase allowable flow rate and respond to polymer fouling, then the column can handle higher flow rates and resist fouling, but channeling phenomenon occurs due to uneven feed distribution, reducing column efficiency
Solution Approach 1:
The feed supply system is segmented into multiple spray nozzles distributed around the column cross-section, with each nozzle serving a specific radial zone. This segmentation of the feed introduction function prevents channeling by ensuring uniform feed distribution across different regions of the column, while maintaining the high flow rate capability of dual flow trays
Solution Approach 2:
The spray nozzles are positioned at different radial distances from the column center, creating local variations in spray coverage zones. This local quality approach ensures that feed is distributed uniformly across the entire column cross-section, preventing channeling phenomenon while maintaining high allowable flow rates
2Object-affected harmful factors
If dual flow trays operate without downcomers to prevent polymer fouling, then resistance to fouling increases, but liquid redistribution cannot occur, leading to channeling and decreased overall efficiency
Solution Approach 1:
Feed is introduced at multiple locations around the column cross-section through spray nozzles before the liquid reaches the trays. This preliminary distribution action ensures uniform feed allocation to different radial zones, preventing channeling and maintaining high overall efficiency without requiring downcomer-based liquid redistribution
3Device complexity
If feed is not uniformly distributed in the column, then the dual flow tray structure can be maintained, but channeling phenomenon occurs, decreasing gas-liquid contact area and product quality
Solution Approach 1:
The feed distribution approach transitions from a single-point or single-line introduction to a three-dimensional spatial distribution pattern using multiple spray nozzles positioned at different radial locations and angles. This dimensional expansion of feed introduction ensures uniform distribution across the column cross-section, maintaining tray structure simplicity while improving product quality through enhanced gas-liquid contact area
