Ascorbic Acid Reducing Agents for NO2 and CO Scrubber Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing nitrogen dioxide (NO2) and carbon monoxide (CO) emissions from hydrocarbon burn processes are inefficient and can produce harmful byproducts, such as hydrogen sulfide gas, when using traditional sulfur-based reducing agents, which are also hazardous to handle.
Innovation Solution
The use of ascorbic acid-based reducing agents, including mono-dehydroascorbic acid, sodium ascorbate/erythorbate, and ammonium ascorbate/erythorbate, which are safer, more effective, and do not form harmful gases, combined with copper silver ionization to treat NO2 and CO emissions in standard scrubber systems without requiring modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sulfur-based reducing agents are used to remove nitrogen dioxide, then nitrogen dioxide removal effectiveness is improved, but harmful hydrogen sulfide gas is formed and handling safety deteriorates
Solution Approach 1:
The patent changes the chemical parameter of the reducing agent from sulfur-based compounds to ascorbic acid-based compounds. This substitution fundamentally alters the chemical reaction pathway, eliminating hydrogen sulfide formation while maintaining nitrogen dioxide removal effectiveness through redox reactions that produce harmless byproducts.
Solution Approach 2:
The patent converts the potentially harmful interaction between reducing agents and nitrogen dioxide into a beneficial process by selecting ascorbic acid derivatives that react to form non-toxic products rather than harmful hydrogen sulfide gas, thus transforming a hazardous chemical process into a safe one.
2Productivity
If sulfur-based reducing agents are used to treat nitrogen dioxide, then nitrogen dioxide removal is achieved, but handling safety and operational ease deteriorate
Solution Approach 1:
The patent changes the chemical composition parameter from sulfur-based to ascorbic acid-based reducing agents, which fundamentally improves handling safety while maintaining removal effectiveness. Ascorbic acid and its derivatives are non-hazardous, non-corrosive, and safe to handle, eliminating the safety concerns associated with sulfur compound handling.
3Device complexity
If standard scrubber systems are used without modifications, then system simplicity is maintained, but treatment effectiveness for both nitrogen dioxide and carbon monoxide deteriorates
Solution Approach 1:
The patent makes the scrubber system multi-functional by using ascorbic acid-based reducing agents that simultaneously treat both nitrogen dioxide and carbon monoxide through dual chemical mechanisms: redox reactions for nitrogen dioxide and copper-mediated reactions for carbon monoxide, eliminating the need for separate treatment systems.
Solution Approach 2:
The patent employs a composite chemical system combining ascorbic acid derivatives with copper compounds, creating a synergistic treatment mechanism that addresses both nitrogen dioxide and carbon monoxide removal within a single scrubber system, thereby improving dual pollutant treatment effectiveness without increasing system complexity.

Function Achieved in This Case
These ascorbic acid-based compounds enhance NO2 absorption and reduce CO emissions effectively in standard scrubber systems, avoiding the formation of harmful gases and allowing for simultaneous treatment of both pollutants without additional system modifications, ensuring compliance with environmental regulations.
Implementation Method 1
these chemicals when applied in a controlled manner have a stronger redox (reduction-oxidation) capability unique to NO2 compounds thus making them more efficient at reducing nitrogen dioxide levels
Implementation Method 2
copper compounds in a form effective for treating carbon monoxide emissions thus making the combined chemistry of ascorbic acid and copper compounds an effective simultaneous treatment for both nitrogen dioxide and carbon monoxide emissions
