Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adsorbents are used for purifying reservoir water and fracking fluids, then some degree of purification is achieved, but the purification efficiency is low and the operational complexity and cost increase
Solution Approach 1:
The invention changes the physical and chemical parameters of the adsorbent by using rubber particles with specific size ranges (0.1-5mm) and oil content (1-40%), combined with specific fillers like carbon black, to optimize adsorption efficiency while simplifying handling operations
Solution Approach 2:
The invention creates a composite adsorbent material combining rubber particles with fillers such as carbon black, calcium carbonate, or magnesium oxide, which enhances purification efficiency while maintaining simple handling characteristics through the composite structure
2Reliability
If adsorbent materials are used for hydrocarbon removal, then organic substances are adsorbed from fluid media, but the handling and exchangeability of adsorbents is poor
Solution Approach 1:
The invention optimizes particle size parameters to 0.1-5mm and controls oil content at 1-40%, which improves adsorption efficiency while ensuring particles are easy to handle, transport, and exchange in practical applications
Solution Approach 2:
The invention employs rubber particles that can be easily replaced and disposed of after use, simplifying the exchange process. The particles are designed to be used in fixed beds or fluidized beds where they can be easily removed and replaced without complex regeneration systems
3Reliability
If known adsorption systems are implemented, then hydrocarbon adsorption is performed, but the systems are costly and inefficient
Solution Approach 1:
The invention uses rubber particles, which are inexpensive and readily available as byproducts of rubber industry processes. This eliminates the need for expensive specialized adsorbent materials while maintaining effective hydrocarbon removal performance
Solution Approach 2:
The invention optimizes particle characteristics including size (0.1-5mm), oil content (1-40%), and filler composition to achieve high adsorption efficiency at low cost, eliminating the need for expensive system configurations while improving performance
