Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing CO2 sequestration systems are used, then CO2 storage is achieved, but they cannot handle high-flow CO2 sources (exceeding 40 Nm3/h) and have high costs that limit scalability
Solution Approach 1:
The system divides the high-flow CO2 stream into multiple smaller flows by connecting several drying modules in parallel, each handling a portion of the total CO2 flow. This segmentation allows the system to scale处理能力 by adding more modules while each individual module operates within its optimal flow range.
Solution Approach 2:
The drying modules serve dual functions: they act as both CO2 sequestration units and wood drying processors. This multi-functionality increases system productivity by utilizing the same infrastructure for two purposes, thereby improving scalability without proportionally increasing costs.
2Quantity of substance
If multiple drying modules are implemented to handle high CO2 flows, then CO2 sequestration capacity increases, but system costs increase making it difficult to implement
Solution Approach 1:
The system merges the CO2 sequestration function with the wood drying function into a single integrated process. By combining these two operations, the system achieves CO2 sequestration without requiring separate dedicated infrastructure, thereby reducing overall implementation costs while maintaining high sequestration capacity.
Solution Approach 2:
The drying modules utilize the CO2 gas itself as both the drying medium and the sequestration agent. The CO2 is circulated through the wood material, performing drying, and then recaptured for storage, creating a self-sufficient system that reduces external resource requirements and operational costs.
3Quantity of substance
If liquefied CO2 is supplied using cylinders, then CO2 can be stored and distributed, but volume and cost limitations prevent industrial scale-up
Solution Approach 1:
The system changes the physical state parameter of CO2 from liquid (cylinders) to gas phase distribution. By utilizing gaseous CO2 directly from industrial sources through a distribution network, the system eliminates the need for large-volume liquid storage infrastructure while maintaining adequate CO2 supply for industrial-scale operations.
4Quantity of substance
If high-flow CO2 sources are used, then CO2 availability increases, but uncontrolled injection occurs making it difficult to guarantee sufficient and secure supply for drying cycles
Solution Approach 1:
The system incorporates feedback control mechanisms that monitor CO2 flow rates and adjust distribution accordingly. Sensors detect actual CO2 availability and system demand, dynamically regulating valve openings and pump speeds to maintain controlled injection rates even when source flow varies, thereby ensuring reliable and secure supply for drying cycles.
Solution Approach 2:
The CO2 distribution system employs dynamic调节 capabilities with adjustable flow control valves and variable speed pumps that can adapt to changing source availability and drying module demands in real-time, transforming the static high-flow source into a controllable supply system.
