Controls Diesel Bug

The Problem
Supertech 159 from Chemplex provides a bacteriostatic action that controls the growth of bacteria (diesel bug). In bulk storage tanks, the interface between the fuel and water, which is a result of condensation, creates an environment friendly to bacteria development. Supertech 159 provides a dual action response to this problem: Supertech 159 kills the existing bacteria. Supertech 159 picks up the water, thereby eliminating the environment that enables new bacterial growth. It generates an emulsification action that allows moisture to be carried through the combustion chamber so that it can be burned off harmlessly.

The Symptoms
Microbial infection of the fuel oil causes discoloration, turbidity and fouling problems. Pistons and cylinders may wear faster. Filters and fuel injection nozzles can become plugged within a few hours of adding contaminated fuel.

The Solution
Add Chemplex Supertech 159 to fuel at a ratio of 1:1280.

Product Testing
In tests performed in accordance with ASTM D-1744, 1% water was added to two fuel samples. Chemplex Supertech 159 was added to only one of the fuel samples. Both were vigorously shaken and then allowed to rest for at least one hour to allow for separation of the fuel and water. Testing of the upper layer in both samples showed a 4% improvement. The fuel treated with Supertech 159 showed and increase of 2 ppm of water in the fuel samples, which shows the water was emulsified in the fuel instead of separating. Statistically, this is a significant reduction, and with a consistent maintenance program, it will minimize the accumulation of water in fuel storage tanks.

Sludge Inhibitor for Fuel Oils

The Problem
The trend in the petroleum industry is an increased demand for lighter products. This has resulted in the conversion of heavier fuel oils into lighter distillates through the use of hydrotreating. As a consequence, today’s diesel fuels contain a higher concentration of sulfur, vanadium and asphaltenes. Asphaltenes are particularly troubling because they are non-volatile and of a high molecular weight.   When allowed to, these settle out to form a layer of sludge in the bottom of fuel storage tanks that becomes a gelatinous, non-volatile layer nearly impervious to removal efforts.

The Solution
Add Chemplex Supertech 159 to fuel at a ratio of 1:1280. Supertech 159 prevents asphaltenes from forming into sheets and dropping to the bottom. Continued use of Supertech 159 keeps asphaltenes suspended in fuel where they are effectively burned up in the combustion process. Use of Supertech 159 will also clean existing sludge from old storage tanks.

Product Testing In laboratory tests done in accordance with D2274 Oxidation Stability Tests, the results showed a dramatic reduction in sludge content from 102 milligrams to 1.1 milligrams per 100 milliliters, using treated #2 diesel fuel stored at 250º F for 216 hours. Oxygen is bubbled through fuel at 203º F and sediment and color are analyzed. Before: 2.63 mg/100mL untreated diesel fuel #2 After: 0.60 mg/100mL treated diesel fuel #2 at a ratio of 1:1280.

Corrosion and Rust Inhibitor

Supertech lays down a long lasting microscopic residue of high viscosity polymetric corrosion inhibitor that bonds to metal surfaces. This provides continuing protection to fuel system and storage tanks. The water in diesel attacks metal surfaces in storage tanks, which results in rust. Regular use of Supertech eliminates the rust and corrosion problem.

Marine Engine Lubricant (US only)

New U.S. fuel regulations eliminating sulfur in diesel fuel has created an injector lubricity problem. Injectors designed for traditional sulfur content fail when using low or no sulfur diesel fuel. Chemplex Supertech adds significant lubricity value to fuel when used at maintenance treat rates. Ball on Cylinder Lubricity Evaluator (BOCLE) tests demonstrate the improved lubricity value in treated versus non treated fuels.
