Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If CO2 is released into the atmosphere during blue hydrogen production, then the production process can proceed without additional treatment equipment, but environmental pollution increases and carbon dioxide accumulates in the atmosphere
Solution Approach 1:
The patent converts the harmful CO2 byproduct into a beneficial resource by implementing a recovery system that captures CO2 from the blue hydrogen production process and transforms it into liquid CO2 for industrial reuse, thereby eliminating environmental pollution while creating economic value
Solution Approach 2:
The patent introduces a treatment module as an intermediary component between the blue hydrogen reforming apparatus and the recovery unit, which includes compression and cooling devices that facilitate the transformation of gaseous CO2 into liquid CO2 for storage and reuse
2Object-affected harmful factors
If a comprehensive CO2 collection and reuse system is implemented, then CO2 can be recovered and reused without releasing into the atmosphere, but the system requires large physical space and complex infrastructure
Solution Approach 1:
The patent divides the CO2 recovery system into modular components including a blue hydrogen reforming apparatus, a separate treatment module with compression and cooling devices, and a recovery unit, allowing for compact arrangement and flexible installation in limited spaces
Solution Approach 2:
The patent implements a nested configuration where the treatment module is positioned between the reforming apparatus and recovery unit, with compression devices and cooling devices integrated in a compact manner, and the recovery unit storing liquid CO2 in an efficient space-utilizing design
