Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing haloamines result in the accumulation of harmful halogen polyoxyanions such as chlorate and perchlorate, posing health risks and regulatory challenges due to their degradation during storage of halogen-containing oxidant solutions.
Innovation Solution
On-site generation of halogen-containing oxidant solutions and immediate reaction with a nitrogen source to produce haloamines, eliminating intermediate storage and thereby reducing or eliminating halogen polyoxyanions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If halogen-containing oxidant solutions are stored for later use, then convenience of operation is improved, but harmful halogen polyoxyanions accumulate during storage
Solution Approach 1:
The system performs preliminary generation of halogen-containing oxidants immediately before they are needed for haloamine production, eliminating the storage step that causes polyoxyanion accumulation. The oxidants are generated on-demand and used immediately in the reaction with nitrogen sources.
Solution Approach 2:
The harmful storage step is extracted and removed from the process flow. Instead of storing oxidant solutions and then using them, the system generates oxidants and immediately reacts them with nitrogen sources in a continuous on-site process, eliminating the intermediate storage phase where degradation occurs.
2Reliability
If halogen-containing oxidant solutions are stored, then availability of reagents is improved, but degradation of actives occurs
Solution Approach 1:
The system generates halogen-containing oxidants on-site and immediately uses them for haloamine production without external storage. The continuous on-demand generation and immediate consumption eliminates the stability issues associated with storage while ensuring reagent availability.
Solution Approach 2:
The system maintains continuous generation and immediate consumption of halogen-containing oxidants in an uninterrupted on-site process. This continuous flow eliminates idle storage time, preventing degradation while ensuring consistent reagent availability for haloamine production.
3Ease of manufacture
If commercial halogen-containing oxidant solutions are used, then ease of manufacture is improved, but significant amounts of halogen polyoxyanions are present
Solution Approach 1:
The system introduces an on-site generation step as an intermediary between raw material acquisition and final haloamine production. This intermediate on-demand generation process produces fresh oxidants without the storage-induced polyoxyanion contamination found in commercial solutions, while maintaining manufacturing simplicity.
4Object-generated harmful factors
If on-site generation and immediate reaction is implemented, then halogen polyoxyanions are reduced, but process complexity increases
Solution Approach 1:
The system merges the oxidant generation step and the haloamine production step into a single integrated on-site process. By combining these operations and eliminating separate storage and handling steps, the overall process complexity is minimized while achieving the benefit of reduced polyoxyanion formation through continuous immediate use.
