Solution Overview
Problem
Industrial water systems face inefficiencies due to the formation of hydrogen sulfide and iron-induced scale, which can lead to equipment damage and increased maintenance costs, necessitating effective compositions to mitigate these contaminants.
Innovation Solution
A multifunctional additive comprising a biochelant and a sulfide scavenger is introduced, which can be used in industrial water systems to reduce hydrogen sulfide and prevent iron-induced scale formation, optionally including corrosion and scale inhibitors, to enhance solubility and prevent precipitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional water treatment methods are used, then some level of contaminant control is achieved, but hydrogen sulfide and iron-induced scale formation continue to occur causing equipment damage
Solution Approach 1:
The patent combines a biochelant and a sulfide scavenger into a single multifunctional additive composition. The biochelant specifically targets iron-containing contaminants while the sulfide scavenger addresses hydrogen sulfide, creating a unified treatment solution that simultaneously addresses multiple contaminants that conventional single-function treatments cannot effectively handle
Solution Approach 2:
The additive composition performs multiple functions: it chelates iron, scavenges sulfide, prevents scale formation, and inhibits corrosion. This multi-functional approach replaces the need for multiple separate treatment chemicals, providing comprehensive protection against various contaminants including hydrogen sulfide and iron-induced scale that conventional methods fail to address effectively
2Productivity
If industrial water is used without treatment, then operational simplicity is maintained, but contaminants increase leading to process inefficiencies and equipment damage
Solution Approach 1:
The biochelant component automatically binds to iron-containing contaminants through chelation, and the sulfide scavenger autonomously reacts with hydrogen sulfide in the water system. This self-acting mechanism continuously mitigates contaminant buildup without requiring external intervention or complex control systems, maintaining process efficiency while the additive works autonomously to prevent equipment damage
3Reliability
If multiple separate additives are used to address different contaminants, then comprehensive contaminant control is achieved, but system complexity and maintenance requirements increase
Solution Approach 1:
The patent merges the functions of iron chelation and sulfide scavenging into a single additive composition containing both biochelant and sulfide scavenger components. This unified approach eliminates the need to manage multiple separate additive dosing systems, reducing operational complexity while maintaining comprehensive control over both iron-induced scale and hydrogen sulfide contaminants
