Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for purifying oil and oil products from sulfur-containing compounds are complex and generate waste, while current methods for reducing sulfur content in diesel fuel only and do not effectively address sulfur dioxide emissions in exhaust gases during combustion.
Innovation Solution
The method involves treating liquid hydrocarbon motor fuels with hydrogen peroxide and/or a strong aqueous solution of iron oxides in a fully-developed cavitation mode, followed by separation using polymer membranes to achieve a sulfur content of 20 ppm or less, and further reducing sulfur dioxide emissions to zero during combustion without additional chemical substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing methods for purifying oil from sulfur compounds are used, then sulfur content is reduced, but the process complexity increases and waste is generated
Solution Approach 1:
The invention extracts sulfur-containing compounds from fuel by adding extraction agents (acidic or basic substances) that selectively bind to sulfur compounds, forming separable complexes. This allows sulfur removal without complex multi-step processes, directly addressing the contradiction between purification effectiveness and process simplicity
Solution Approach 2:
The invention changes the chemical parameters of the fuel by introducing extraction agents that alter the solubility and separability of sulfur compounds. By adjusting parameters such as pH through acidic or basic additives, the method enables efficient sulfur removal while maintaining process simplicity
2Manufacturing precision
If existing methods for purifying diesel fuel from sulfur compounds are used, then sulfur-containing compounds content is reduced, but waste is formed that must be disinfected or stacked
Solution Approach 1:
The invention enables recovery and reuse of the extraction agents (acidic or basic substances) after they have bound sulfur compounds. The spent extraction agent-sulfur complex can be regenerated and reused, minimizing waste disposal requirements and addressing the environmental concern of waste generation
Solution Approach 2:
The invention converts the harmful sulfur compounds into separable complexes with extraction agents, transforming a harmful substance into a manageable form that can be easily removed and disposed of or regenerated, thereby converting a waste problem into a solvable separation problem
3Object-affected harmful factors
If sulfur content in fuel is reduced to 20 ppm or less, then emission standards are met, but additional processing steps are required
Solution Approach 1:
The invention performs preliminary treatment of fuel with extraction agents before combustion, pre-removing sulfur compounds in advance. This preliminary action ensures that the fuel meets emission standards (20 ppm or less) without requiring complex post-processing or multiple treatment stages, thereby maintaining processing efficiency
