1Productivity
If traditional mutual solubility test method is used, then measurement precision is maintained, but testing time is excessive and operation is laborious
Solution Approach 1:
The patent replaces traditional mechanical mixing and visual observation methods with an optical detection system. A laser beam passes through the fuel mixture in a cuvette, and a photodetector measures light transmission intensity. This optical system automatically detects mutual solubility based on refractive index changes, eliminating manual intervention and significantly reducing testing time while maintaining precision.
Solution Approach 2:
The patent introduces an optical intermediary (laser light) to detect the mutual solubility state of fuel mixtures. The light beam acts as a mediator that interacts with the fuel sample, and changes in light transmission indicate changes in mutual solubility. This intermediary approach enables rapid, automated detection without direct mechanical manipulation of the sample.
2Ease of operation
If traditional test method is used, then comprehensive measurement is achieved, but operation complexity increases
Solution Approach 1:
The system performs self-service through automated control. The controller automatically controls the injection pump to add biomass fuel to the cuvette, activates the laser and photodetector for measurement, and processes the results without user intervention. This automation simplifies operation while the modular design keeps individual components simple.
Solution Approach 2:
The optical detection system serves multiple functions: it detects mutual solubility, determines phase separation, and can potentially measure concentration ratios. This multi-functionality reduces the need for separate testing apparatus, simplifying the overall operational process while maintaining comprehensive measurement capabilities.
