Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current additives for ultra-low sulfur diesel fuels lack a single package solution that effectively improves both lubricity and conductivity, and existing solutions face issues with stability, compatibility, and consistency over time.
Innovation Solution
A reaction product comprising a fatty acid composition, glycerol tricarboxylate, polysulfone, polyamine, alkylated benzene sulfonic acid, and a phenol derivative, formulated through a single-pot process, is used as a single additive package to enhance lubricity and conductivity of ultra-low sulfur diesel fuels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate lubricity improvers and conductivity additives are used in ULSD fuels, then lubricity and conductivity properties can be improved individually, but the complexity of additive application and dosing increases
Solution Approach 1:
The patent combines multiple additive functions (lubricity improvement and conductivity enhancement) into a single multifunctional additive package. This single package contains both lubricity improver components and conductivity improver components, eliminating the need for separate dosing operations and reducing application complexity while maintaining both lubricity and conductivity benefits
Solution Approach 2:
The additive package is designed with multi-functionality, where a single additive formulation performs multiple functions simultaneously: improving lubricity through fatty acid-based components and enhancing conductivity through polysulfone and polyamine components. This universal additive solution addresses multiple fuel property deficiencies in one application
2Reliability
If multiple commercial additives are blended together, then both lubricity and conductivity properties can be enhanced, but the stability and compatibility of the mixture over time becomes uncertain
Solution Approach 1:
The patent formulates a composite additive package where lubricity improver components (fatty acids, glycerol esters) and conductivity improver components (polysulfone, polyamine, sulfonic acid) are combined in a unified formulation. This composite structure ensures compatibility between different additive types and maintains stability over time, avoiding the precipitation or degradation issues that arise from blending separate commercial additives
3Object-affected harmful factors
If ultra-low sulfur diesel fuels are produced through hydro-treating processes, then sulfur content is reduced to meet environmental standards, but lubricity and conductivity properties deteriorate
Solution Approach 1:
The patent addresses the harmful effect of hydro-treating processes that remove polar compounds and degrade fuel properties. By adding a multifunctional additive package containing fatty acids for lubricity and polysulfone/polyamine for conductivity, the patent converts the harm of sulfur removal into an opportunity to precisely control and optimize fuel properties through targeted additive formulation
