Legal Citation
Summary of the Inventive Concept
The present inventive concept leverages tucaresol and its analogs to address corrosion and pollution challenges in industrial processes, offering a novel solution for industries such as oil and gas, wastewater treatment, and fuel cells.
Background and Problem Solved
The original patent focused on the use of tucaresol and its analogs in pharmaceutical compositions for cancer treatment. However, these compounds also exhibit properties that make them suitable for addressing corrosion and pollution issues in industrial processes. The present inventive concept addresses the limitations of current corrosion inhibitors and pollutant removal methods, which often have environmental and health concerns, or are ineffective in certain applications.
Detailed Description of the Inventive Concept
The inventive concept involves the use of tucaresol and its analogs as corrosion inhibitors in industrial processes, particularly in the oil and gas industry, where they can prevent corrosion of metal surfaces in contact with process fluids such as crude oil or natural gas. Additionally, these compounds can be used to remove heavy metals and other pollutants from wastewater, and as proton conductors in fuel cells, enhancing their efficiency and stability.
Novelty and Inventive Step
The new claims introduce a novel application of tucaresol and its analogs in industrial processes, which is distinct from their original use in pharmaceutical compositions. The inventive concept's use of these compounds as corrosion inhibitors, pollutant removers, and proton conductors represents a non-obvious and innovative solution to the problems addressed.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include the use of tucaresol and its analogs in other industrial processes, such as mining, construction, or manufacturing, where corrosion and pollution are significant concerns. Variations of the inventive concept could also involve the combination of these compounds with other materials or technologies to enhance their effectiveness.
Potential Commercial Applications and Market
The inventive concept has significant commercial potential in various industries, including oil and gas, wastewater treatment, and fuel cells. The market for corrosion inhibitors and pollutant removal methods is substantial, and the present inventive concept offers a novel and effective solution that could capture a significant share of this market.
