Power Research PRI-27

• PRI- 27 contain specific chemicals to improve thermal stability of VLSFO/HFO.
• Compatibility is also improved if having to comingle two different stems of VLSFO/HFO.
• PRI-27 is a verified technology for optimizing combustion of VLSFO/HFO in all marine diesel engine types, safely elevating peak combustion pressure (PMAX) while reducing post combustion deposits.
• PRI27 significantly reduces post combustion deposits, maintaining engine component cleanliness, especially at reduced operating loads. Overhaul intervals are extended, and lube oil life is improved, resulting in enhanced propulsion system efficiency and reliability. PM (visible smoke emissions) are also reduced approximately 30 - 40 percent.
• PRI-27 is formulated with a special combination of highly concentrated dispersants proven to cut sludge precipitation in a range of 35 - 50 percent, recovering lost fuel value.
• At the standard dosage rate of one liter per 12 mt, PRI-27 recovers lost fuel value by reducing sludge precipitation as much as 35-50 percent – protecting fuel delivery systems from excessive wear while permitting more efficient purifier operation.
• Contains only 100 percent active ingredients and no cheap petroleum fillers or iron-based catalysts.
• PRI-27 is a highly complex blend of organic chemistries that mix compatibly with heavy fuel and will not stratify or separate during fuel purification. Purification systems remain cleaner and more efficient when processing PRI-27 treated fuels.

Dosage Rate

PRI-27 is dosed at the rate of 1:12,000 regardless of fuel specifications under ISO 8217. The fixed dosage rate was developed in consideration of the fact that heavy fuel oil characteristics can be widely variable, and that quality standards as proscribed under ISO 8217 do not completely account for all deficiencies associated with fuel performance. Optimal protection is ensured at the 1 liter per 12mt dose rate.

Dosage Method

Power Research Inc. suggests that PRI-27 can be dosed at the main bunker manifold by means of a safe and easily operated air driven gear pump assembly. However, PRI-27 is highly miscible with heavy fuel oil and may be added directly to fuel tanks 15 - 30 minutes prior to bunkering. Agitation from fuel flow into the fuel tank typically provides a sufficient mixture.
