Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-sulphur content fuels, such as diesel and kerosene, have reduced electrical conductivity, leading to static charge accumulation and discharge risks during handling, which are mitigated by anti-static additives but at a high cost and with limited effectiveness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-static additives are used to increase electrical conductivity of low-sulphur fuels, then static charge management is improved, but the cost of fuel treatment increases
Solution Approach 1:
The invention combines a polymer component (A) with an anti-static additive component (B) to form a composite additive composition. The polymer component, formed from specific monomers including compounds of formula (I), (II), and (III), works synergistically with the anti-static additive (olefin polysulfone and polymeric polyamine reaction product) to enhance electrical conductivity. This composite approach allows achieving the required conductivity improvement with lower overall additive quantities, thereby reducing cost while maintaining reliable static charge management.
2Reliability
If commercial anti-static additives are used alone, then electrical conductivity is improved, but the effectiveness is limited and cost is high
Solution Approach 1:
The invention changes the compositional parameters of the additive system by introducing a polymer component with specific monomer compositions (formulas I, II, and III) in controlled ratios. The polymer component (A) is combined with anti-static additive (B) in weight ratios from about 1:1 to about 500:1. This parameter optimization enables achieving superior electrical conductivity improvement with reduced additive quantities, thereby increasing effectiveness per unit cost compared to using commercial anti-static additives alone.
