Power Research PRI-RS

• PMAX increase - SFOC reduction - PRI-RS elevates peak firing pressure (PMAX) in a range of 4 - 6 bars. In so doing, specific fuel oil consumption (SFOC) is reduced 1.0 - 1.5 percent (0.25% reduction for every bar PMAX increase).
• Sludge Reduction - PRI-RS contains a series of highly effective dispersant chemistries verified to inhibit organic fuel sludge by as much as 50%. Not only are fuel delivery systems kept sludge free, the fuel value recovered provides a very significant return on investment.
• Carbon & Vanadate Deposit Prevention - PRI-RS greatly reduces post-combustion carbon and soot. Highly effective vanadium control chemistries prevent formation of low melting point vanadates - preventing damaging high temperature corrosion.
• Emissions Compliance - The cleaner combustion proven with PRI-RS results in greatly reduced visible smoke (particulate reduction), and major reductions in other emissions ensuring compliance with Marpol Annex VI standards.
• PRI-RS is a highly complex blend of organic chemistries that once blended with fuel oil, will not stratify or separate, even with fuel purification. In fact, purification systems remain cleaner and more efficient when processing PRI-RS treated fuel oils.

Dosage Rate

PRI-RS is dosed at the rate of 1:4000. The fixed dosage rate concept was developed in consideration of the fact that fuel oil quality is widely variable. PRI-RS is formulated to address not only normal fuel oil combustion behavior, but combustion behavior that results from a matrix of worst case conditions that negatively affect normal engine operation. Among these often-hidden conditions are blending incompatibilities, off spec or poor quality fuels, reduced ignition quality, and adverse Sodium/Vanadium (Na/V) ratios.

Dosage Method

Power Research Inc. recommends dosing via air vent/manhole or via transfer pump 30 minutes or less before bunkering begins. This is preferred as the optimum method to provide early prevention of organic sludge precipitation, hence preventing typical losses in fuel value.
