Technical Data Sheet

"rb bertomeu” Mg Colloidal 28
Vanadium corrosion inhibitor and ash acidity reducer
Download PDF

Vanadium, Sodium and SO3 corrosion inhibitor for Heavy Fuel Oil and crude oil in Gas Turbines, Boilers, Furnaces and 2-stroke big engines.

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



The “rb bertomeu” Mg Colloidal additive contains 72-picometer Magnesium molecules (pm: 10-12 meters) with a surface area of 1,800 m2/gram soluble in the fuel (Technical Document RB-31) 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 a colloidal dispersion.

Magnesium molecules fully react with Vanadium and Sodium, do not generate residues or ash and do not cause scale in the gas circuit.

The Magnesium Oxide or Hydroxide nanoparticles, smaller than 100 nanometers, are 1,000 times smaller and are more reactive than micrometer particles of <2 microns.



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-temp. 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 and reduce the acid corrosion.
