Fuelpower Soot Remover Liquid Plus

Newly formulated Unitor™ FuelPower™ Soot Remover Liquid Plus increases the cleaning/maintenance interval for your exhaust gas economizer/boiler from every 3 months to 12–15 months.

Extensive yearlong trials on MV Tonsberg, a 76500 GRT Ro-Ro vessel propelled by MAN B&W 7 Cylinder L70 ME-C8, clearly showed tangible benefits of using our new treatment chemical. The use of our new Unitorâ„¢ FuelPowerâ„¢ Soot Remover Liquid Plus provides clear benefits: 

  • Keeps EGB free of soot
  • Increases cleaning interval to 12-15 months
  • Prevents acid formation
  • Prevents cold corrosion
  • Reduces risk of soot fires
  • Environmentally friendly by reducing emission of soot particles
  • Reduces the challenge of dealing with the acidic wash water every 3 months
  • Absence of heavy metal compounds such as copper nitrate
  • 24/7 support for your needs



  • Untreated fuel oil leads to frequent cleaning, every 2-3 months interval
  • Using additional time, money and resources to carry out a cleaning job when vessel is in port, additional strain on resources
  • Wear and tear of equipment and labour needed to carry out the cleaning


  • Challenge of discharging the dirty wash water as it contains acidic soot that cannot be disposed directly into sea water, requiring additional waste management


  • Reduced efficiency as soot deposits are extremely insulating - just a 1mm layer of soot can cut the efficiency of the exhaust gas boiler by up to 10%
  • Soot fires result in overheating due to soot deposit
  • Cold corrosion in case of slow steaming with low exhaust temperatures


Low-quality fuel

  • Contaminants such as vanadium, sodium, aluminium, silica, potassium and other metals can cause incomplete combustion

Design of exhaust gas boiler

  • Incorporation of low velocity flue gas for higher efficiency may result in higher soot deposit


  • Reduction in exhaust gas temperature from modern engines and slow-steaming practices increases the tendency for deposit formation or cold corrosion in the exhaust gas boiler
