LK-7318

Silicone polyether Co-Polymer Surfactant

Introduction:

LK-7318 is a high-performance silicone polyether co-polymer surfactant engineered to reduce surface tension and optimize process efficiency across a wide range of industrial applications. Its unique dual-functionality makes it exceptionally versatile and valuable in two key areas:
Crude oil de-emulsification – LK-7318 enables rapid and efficient separation of oil and water at room temperature, significantly enhancing processing speed and clarity. With an HLB value of approximately 7, it offers a well-balanced hydrophilic-lipophilic profile, making it highly effective in oil-water systems and compatible with a broad range of surfactants.
Sulfur pelletisation – In sulfur processing, LK-7318 acts as a powerful anti-adhesion agent, preventing molten sulfur from sticking to equipment surfaces. This ensures smoother pellet formation, reduces downtime for cleaning, and improves overall operational safety and productivity. Useful for Bath system.

Key Features:

  • Efficient De-Emulsification for Crude Oils
  • Boosts Performance of Other De-Emulsifiers (1–50%)
  • Clear Solution in C8 Alcohols
  • Reduces foam in Crude Systems
  • Outstanding Release & Anti-Adhesion Properties
  • High Thermal & Shear Stability
  • Improves Operational Efficiency & Reduces Maintenance

Application:

Crude Oil – Water Separation:

LK-7318 serves as a powerful silicone-based de-emulsifier for oilfield operations. It accelerates the removal of water from hydrocarbon products, functioning effectively either standalone or mixed with other de-emulsifiers.

  • Works across a broad pH range
  • Compatible with most surfactant systems
  • Enhances separation speed even at low dosage levels (1%–50%)
    Reduces foaming issues commonly found in crude processing

Sulfur Pelletisation:

  • In refineries, sulfur pelletisation converts molten sulfur into solid pellets for safer handling and storage. LK-7318 improves this process by: Preventing molten sulfur from sticking to conveyor belts, drums, or other processing surfaces
  • Improving safety by minimizing acid formation and corrosion
  • Enhancing pellet quality and reducing equipment cleaning downtime
  • Recommeded dosage : Prepare a 2.5–3% solution in distilled water (pH 6–7) in bath system
