NMR Spectrometry for Catalytic Fines Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining catalytic fines in fuel oil are cumbersome, time-consuming, and expensive, and fail to accurately quantify small particles, making it difficult to monitor and control their levels, especially in real-time on location such as on board vessels.
Innovation Solution
The method employs Nuclear Magnetic Resonance (NMR) spectroscopy to quantify aluminum in fuel oil, which correlates directly to the presence of catalytic fines, allowing for both qualitative and quantitative determination of catalytic fines, enabling real-time monitoring and cost-effective analysis on-site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional laboratory chemistry analysis methods are used to determine catalytic fines, then measurement precision can be achieved, but the process becomes time-consuming and expensive, preventing real-time monitoring
Solution Approach 1:
The patent replaces traditional mechanical/chemical laboratory analysis methods with NMR spectroscopy, a physical measurement technique that can rapidly quantify aluminum content without requiring complex chemical processing, thereby reducing analysis time while maintaining precision
Solution Approach 2:
The patent changes the measurement parameter from indirect chemical analysis to direct physical detection of aluminum nuclei through NMR, enabling real-time monitoring by measuring the magnetic resonance signal intensity which correlates directly with aluminum concentration
2Measurement precision
If conventional analysis methods are used, then quantitative determination is possible, but the system complexity and cost increase, making on-location analysis difficult
Solution Approach 1:
The patent substitutes complex chemical analysis systems with a relatively simple NMR spectrometer that can be deployed on-location, reducing system complexity while maintaining the ability to provide accurate quantitative determination of catalytic fines
3Quantity of substance
If centrifuges and settling tanks are used to remove catalytic fines, then some particles can be separated, but particles smaller than 5 microns cannot be removed due to their small size and light weight
Solution Approach 1:
The patent replaces mechanical separation methods (centrifuges, settling tanks) with NMR spectroscopy for detection and quantification, enabling accurate measurement of all particle sizes including those too small to be mechanically separated, thereby improving both removal efficiency assessment and small particle detection
