Cleaning additives

Alkaline (Caustic Potash)

Based on Potassium Hydroxide. Primarily used for the saponification of vegetable and animal oils and fats. The potassium salt of a fatty acid produces a softer soap during saponification compared to the sodium salt, which means that potash cleaners tend to be more effective and are less likely to produce white residues on the surface of the tank. To be used in fresh water only.

Alkaline (Caustic Soda)

Based on Sodium Hydroxide. Saponification of vegetable and animal oils and fats. Produce harder soaps during the saponification process compared to potash and as such, there is an increased risk of the formation of white residues on the surface of the tank, particularly at higher temperatures (carbonates). To be used in fresh water only.

Alkaline Safety (Zinc)

Weak alkaline cleaner with suitable pH-Value for zinc silicate coatings. To be used in fresh water only.

Detergent

Wide variety of different products ranging from standard soaps to sophisticated high performance detergents with a wide range of applications. Surface active agents that work by bringing oil and water together “Emulsification”. These products may be usable in freshwater or seawater, depending on the manufacturer’s instructions.

Metalbright / Rust remover

Acid cleaner typically based on Phosphoric acid. Primarily for the removal of white hardness residues like carbonates from caustic or calcium and magnesium soaps from vegetable oils and vegetable fatty acids.  Removal of rust. Upgrade (brightening) of stainless steel cargo tanks. To be used in fresh water only.

Solvent cleaner (Hydrocarbon based)

Based on Petroleum solvents. Solving of residues from black oils, waxes and heavy mineral oil contamination. Can normally be used in fresh water as well as in sea water.

Solvent cleaner (Hydrocarbon free)

Based on water soluble solvents like Gycols, Glycolethers or Ketones. Removal of residual Hydrocarbons. Depending on product usable in fresh water or sea water.

Solvent cleaner (other)

Based on other solvents. Solving of residues from Polyol, Coal Tar, Carbon Black Feedstock and other specific product residues. Depending on product type usable in fresh water or sea water.

Smell Remover

Removal of smell from cargoes that are characterised by a strong or persistent odour. Different type of cleaners with deodorizing and non-deodorizing components. Different application requirements (recirculation, spraying, steaming additive etc.)

Soot Remover

Specifically designed alkaline cleaner for removal of soot from the incomplete combustion of hydrocarbons in an inert gas unit.
To be used in freshwater only.
