Vanadium, Sodium and SO3 corrosion inhibitor for Heavy fuel oil and Crude oil in Gas Turbines, Boilers, Furnaces and big Marine engines.

It neutralizes the inlays and corrosions caused by Vanadium, Sodium, SO3 and reduces the acidity of the ashes.

The "rb bertomeu" Mg Coloidal additive contains Magnesium molecules (Technical Document RB-8) of 72 picometers (pm: 10-12 meters), with surface area of 1,800 m2/gram soluble in fuel, plus nanoparticles of [MgO or Mg(OH)2] of <100 nanometers (nm: 10-9 meters) with surface area of 400 m2/gram and organic solvents in colloidal dispersion.

The Magnesium molecules totally react with Vanadium and Sodium, they doesn't produce residues or ashes and they doesn't leave incrustations at the gas circuit.
The Magnesium Oxide or Hydroxide particles, smaller than 100 nanometers, are 1000 times smaller and ar more reactive than the <2 microns particles.

Soluble in Heavy fuel oil and Crude oil. For boilers, furnaces, gas turbines and big engines.

To prevent slag, deposits, inlays and corrosions caused by Vanadium, Sodium, and Sulphur and to reduce the ashes’ acidity.

It neutralizes corrosion at the combustion chamber and in the high and low temperature circuit. It inhibits the consistent and hard slags formed at the combustion chamber and inlays at the high-temperature gas areas.
It transforms slags, deposits and inlays into fine, inconsistent residues that are easily removed by blowing and in scheduled maintenance.
Increases the ashes’ pH.
