Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sulfur vapor supply is increased to maintain reaction throughput, then productivity is improved, but local sulfur excess state occurs reducing reaction efficiency
Solution Approach 1:
The patent implements a feedback control system where sulfur amount measurement units continuously monitor the sulfur content in the reaction tank, and the supply adjustment unit automatically adjusts the sulfur vapor supply rate based on these measurements. This closed-loop feedback mechanism prevents local sulfur excess states while maintaining high productivity by dynamically balancing sulfur supply with reaction consumption rate.
Solution Approach 2:
The patent changes the supply parameters of sulfur vapor and hydrogen gas based on real-time sulfur amount measurements. By adjusting the supply rate parameters dynamically rather than using fixed rates, the system optimizes the gas supply to match reaction conditions, preventing sulfur excess while maintaining throughput.
2Productivity
If sulfur vapor supply is increased to maintain reaction throughput, then productivity is improved, but hydrogen sulfide production efficiency deteriorates
Solution Approach 1:
The feedback control system measures sulfur amount in real-time and adjusts sulfur vapor supply accordingly, ensuring optimal sulfur-to-hydrogen ratio for maximum hydrogen sulfide production efficiency. This prevents the sulfur excess condition that would otherwise reduce reaction efficiency while maintaining high throughput.
Solution Approach 2:
The system transitions from static fixed-rate gas supply to dynamic supply rates that adapt to changing reaction conditions. The sulfur vapor supply rate is continuously adjusted based on real-time sulfur amount measurements, optimizing the reaction efficiency at each moment while maintaining overall productivity.
3Productivity
If sulfur vapor supply rate is increased, then productivity is improved, but uniform gas interaction is compromised
Solution Approach 1:
The system uses dynamic adjustment of sulfur vapor supply rate based on real-time feedback to maintain uniform gas interaction. By adapting the supply rate to current reaction conditions rather than using a fixed high rate, the system ensures proper mixing and uniform interaction between sulfur vapor and hydrogen gas throughout the reaction tank.
Solution Approach 2:
The supply parameters of sulfur vapor are dynamically changed based on measured sulfur amounts, optimizing the gas supply conditions to maintain uniformity. This parameter adjustment ensures that sulfur vapor is supplied at rates that promote uniform mixing and interaction with hydrogen gas, preventing localized excess regions.
