Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for concentrating water-soluble organic peroxides, such as hydroperoxides, often require heating or the addition of salts or bases, which can destabilize the peroxides and pose safety risks.
Innovation Solution
A process using reverse osmosis to concentrate water-soluble organic peroxides, which involves bringing the peroxide solution into contact with a reverse osmosis membrane, allowing for the separation of a retentate and a permeate, with the peroxide being concentrated in the retentate without the need for heating or adding stabilizing agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If heating is used to concentrate the peroxide solution, then the concentration is improved, but the stability of the peroxide deteriorates and safety risks increase
Solution Approach 1:
The patent replaces thermal heating (thermal field) with reverse osmosis (mechanical field). The reverse osmosis membrane separates water from the peroxide solution through pressure-driven filtration, achieving concentration without heating. This substitution eliminates the thermal decomposition risk while maintaining concentration effectiveness.
Solution Approach 2:
The patent introduces a reverse osmosis membrane as an intermediary substance between the peroxide solution and the concentration process. The membrane acts as a selective barrier that allows water to pass through while retaining the peroxide, enabling concentration without direct thermal or chemical intervention that would destabilize the peroxide.
2Reliability
If salts or bases are added to stabilize the peroxide during concentration, then the stability is improved, but the purity of the peroxide solution deteriorates
Solution Approach 1:
The patent extracts water from the peroxide solution using reverse osmosis, separating the stabilizing function from the concentration process. By removing water through the membrane, the peroxide concentration increases naturally without requiring addition of salts or bases, thus maintaining purity while achieving stability through physical concentration rather than chemical stabilization.
Solution Approach 2:
The reverse osmosis system performs both concentration and stabilization functions simultaneously. The membrane process inherently stabilizes the peroxide by avoiding thermal and chemical stress, while the separation of water achieves concentration. This self-service approach eliminates the need for external stabilizing agents that would compromise purity.
3Productivity
If pervaporation technology is used to remove water, then the water removal efficiency is improved, but the safety risk increases due to heating requirements
Solution Approach 1:
The patent replaces pervaporation (thermal process) with reverse osmosis (mechanical process). Instead of heating the solution to enhance water removal, the reverse osmosis membrane uses pressure-driven filtration to achieve water separation at lower temperatures, eliminating the safety risks associated with thermal processing while maintaining efficient water removal.
Solution Approach 2:
The patent changes the operating parameters from thermal (temperature-driven) to mechanical (pressure-driven). By operating reverse osmosis at controlled pressures rather than temperatures, the process achieves water removal efficiency without the safety hazards of heating. The membrane selectivity provides the necessary separation efficiency without thermal input.
