PRI-SOLV HFO Sludge Control

PRI-SOLV is PRI's remarkably effective sludge dispersant that keeps bunker tanks and fuel system components sludge free at a remarkably low treatment cost per ton of fuel. Cleaner fuel systems mean cleaner fuel delivery, better atomization, and as a result, improved deposit control. Designed to overcome the most challenging fuel blending and compatibility issues, PRI-SOLV recovers lost fuel value by preventing most of the loss of usable fuel that occurs from sludge precipitation - hence increasing fuel utilization.

PRI-SOLV can be directly added to bunker tanks at a ratio from 1:10,000 to 1:20,000, making it PRI's lowest cost solution for increasing vessel profitability. PRI-SOLV;

  • Reduces fuel sludge precipitation 30-to-60 plus percent
  • Prevents fuel incompatibility problems
  • Keeps fuel delivery systems clean


For heavy fuel oils, PRI has developed three extraordinarily effective chemistries:
  • PRI-RS HFO
    Treatment for deposit, sludge and emissions control - PRI's flagship product.
  • PRI-27 HFO
    Treatment for deposit control.
  • PRI-SOLV
    For sludge control.
  • PRI-D
    Industrial diesel treatment for improved lubricity, deposit and emissions control, and long-term storage stability.
  • PRI-D
    Lubricity Testing
