Conductivity Improvers for Hydrocarbon Stability and Combustion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydrocarbon compositions, particularly fuels, face issues with asphaltene separation leading to sludge formation, filter blocking, and poor combustion performance due to low conductivity, which existing static dissipaters do not effectively address as anti-separation agents or combustion stabilizers.
Innovation Solution
Incorporating conductivity improvers into hydrocarbon compositions to enhance stability and combustion performance by acting as both conductivity enhancers and anti-separation agents, potentially combined with dedicated asphaltene dispersants, metal compounds, and organic additives to prevent asphaltene separation and improve combustion efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductivity improvers are used to address static discharge risks, then electrical conductivity is improved, but asphaltene separation and sludge formation are not effectively prevented
Solution Approach 1:
The patent applies multi-functionality by demonstrating that conductivity improvers (specifically quaternary ammonium salts and polysulfone copolymers) simultaneously provide both static discharge protection and asphaltene separation prevention. The conductivity improver serves dual purposes: improving electrical conductivity to prevent static discharge while also acting as an anti-separation agent to maintain asphaltene stability in the hydrocarbon composition.
Solution Approach 2:
The patent merges the functions of conductivity improvement and asphaltene separation prevention into a single additive system. By combining quaternary ammonium salts with polysulfone copolymers in specific ratios, the invention creates a unified formulation that addresses both electrical conductivity requirements and compositional stability requirements, eliminating the need for separate dedicated additives for each function.
2Stability of the object's composition
If dedicated asphaltene dispersants are used to prevent separation, then compositional stability is improved, but combustion performance and conductivity are not optimized
Solution Approach 1:
The patent demonstrates that conductivity improvers can serve as universal additives that simultaneously provide compositional stability, combustion performance, and electrical conductivity. The quaternary ammonium salt/polysulfone copolymer system acts as a multi-functional additive that replaces the need for separate dedicated asphaltene dispersants while also improving combustion characteristics and maintaining conductivity.
3Reliability
If multiple separate additives are used to address different issues, then specific problems are solved, but device complexity and formulation difficulty increase
Solution Approach 1:
The patent combines multiple additive functions into a single integrated formulation. By merging quaternary ammonium salts with polysulfone copolymers in specific weight ratios (ammonium salt: 1-100 parts, polysulfone: 1-100 parts), the invention creates a unified additive package that simultaneously addresses static discharge, asphaltene separation, and combustion performance, thereby reducing formulation complexity compared to using multiple separate additives.
