Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Organic haloamines are unstable in aqueous solutions, making them unsuitable for long-term storage and reducing their potency for biocidal, antibiotic, and antiseptic applications, necessitating an on-site generation process to maintain effectiveness.
Innovation Solution
An electrolytic process is developed to produce aqueous organic haloamine solutions without caustic components, using a brine mixture of a halide-containing salt, an organic amine, and an acid additive, allowing for the adjustment of pH to suit specific applications, and enabling the production of high-concentration haloamine solutions with varying pH values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If organic haloamines are stored in aqueous solutions, then they can be used for biocidal and antiseptic applications, but they become unstable and degrade over time
Solution Approach 1:
The patent applies preliminary action by generating the organic haloamine immediately before use through electrolysis of a stable precursor solution containing organic amine and halide. This on-demand generation ensures the active compound is produced fresh and applied without storage, eliminating degradation while maintaining biocidal effectiveness.
2Quantity of substance
If traditional electrolytic methods are used to produce organic haloamines, then high concentration solutions can be generated, but caustic components are produced that limit pH adjustment
Solution Approach 1:
The patent changes the chemical parameters of the electrolysis system by using a non-caustic electrolyte composition (organic amine and halide salt without hydroxide) and controlling electrolysis conditions to produce haloamine solutions with adjustable pH values ranging from acidic to basic, achieving both high concentration and pH versatility.
Solution Approach 2:
The patent introduces an intermediary approach by using a stable precursor solution containing organic amine and halide salt that can be electrolyzed to generate the active haloamine. This intermediary system allows control over the generation process and final pH without being constrained by caustic components.
3Reliability
If on-site generation of organic haloamines is implemented, then stability and effectiveness are improved, but continuous production capability is reduced
Solution Approach 1:
The patent enables continuous production by implementing a continuous electrolysis process where the stable precursor solution flows through an electrolytic cell, continuously generating organic haloamine at high concentration. This maintains both reliability through fresh generation and productivity through uninterrupted operation.
