Oil Purification Filter Using Polar Separation Aid to Preserve Additives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil purification methods are inefficient in removing contaminants while preserving valuable additives, and there is a risk of losing these additives during filtration.
Innovation Solution
An oil purification filter impregnated with a separation aid that is insoluble in the oil due to its polar properties, adsorbs/absorbs contaminants through chemical interactions, while allowing additives to pass through, using a filter body with a network of cellulose fibers and a layered structure to minimize separation aid loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional filtering techniques are used to remove contaminants from oil, then contamination particles are captured, but valuable additives are also removed
Solution Approach 1:
The filter body is impregnated with a separation aid in only a first part of its volume, creating localized functional zones. The separation aid has specific polar properties that selectively interact with contaminants while being passive toward additives, enabling differentiated treatment of different substances in the oil
Solution Approach 2:
The filter combines the filter body material with a separation aid having substantially different polar properties from the oil. This composite structure creates chemical interaction selectivity where the separation aid adsorbs/absorbs contaminants through polar interactions while allowing non-polar additives to pass through unchanged
2Reliability
If fine filtration is used to capture small particles, then micro and nano particles are removed, but filter pores must be small which blocks valuable additives
Solution Approach 1:
The patent replaces purely mechanical filtration with a chemical interaction-based separation mechanism. Instead of relying on small pore sizes to physically block particles, the separation aid uses polar chemical interactions to selectively adsorb/absorb contaminants. This allows larger pore dimensions that permit additive passage while maintaining high particle removal efficiency through chemical selectivity

AI summary
An oil purification filter for purifying a contaminated oil includes a filter body having a first portion and a second portion, where at least the first portion is impregnated with a separation aid. The separation aid is substantially insoluble in the contaminated oil because of its polar properties, and the separation aid is configured to adsorb/absorb contaminating solids or dissolved impurities in the contaminated oil by chemical interactions. The filter body may comprise one or more sheets of cellulose fibers.
