WRT supplies HFA additives for crude oil, fuel oil, gas oil diesel, gasoline, jet fuel and biodiesel.



Antioxidants delay oxidation, reduce gum formation, prolong storage life and protect fuel systems by increasing resistance to oxidation. WRT has antioxidants for gas oil, gasoline (components), jet fuel and biodiesel.


Bactericides decrease the existence of bacteria, yeast, fungi and algae in water-contaminated fuels. Reducing these microorganisms will safeguard the fuel from a number of quality issues, such as stability, corrosivity and colour degradation. WRT has bactericides for gas oil, gasoline and biodiesel.

Cetane number improvers

Higher cetane fuels have shorter ignition delay periods than lower cetane fuels. Fuels with a higher cetane number offer more time for the fuel combustion process to be completed. This is why higher speed diesels operate more effectively with higher cetane number fuels. Cetane number is a measure of the ignition quality of diesel fuel, rather than the measure of fuel quality.

Cetane improvers encourage early and uniform ignition of the fuel. They discourage premature combustion and an excessive rate of pressure increase in the combustion cycle.

WRT supplies cetane improvers for gas oil, diesel and biodiesel.

CFPP improvers

The cold flow behaviour of diesel fuels typically depends on their molecular structure. As the fuel is cooled, n-paraffins tend to form crystals, coalesce and settle out of the fuel. This causes blocking of the engine filters. The right type of CFPP improver can delay this phenomenon and make sure the wax crystals do not settle. Based on experience, WRT has developed a wide range of (bio) CFPP improvers.

Our additives improve the cold flow properties of diesel fuels, such as gas oil, biodiesel and marine diesel oil.

Cloud point improvers

Cloud improvers lower the temperature at which the first paraffin precipitation is observed. WRT’s additives enhance the cloud point of gas oil, diesel and biodiesel.

Conductivity improvers

These additives improve the conductivity of the fuel, such as permitting electrostatic build-up to safely dissipate without generating a spark. WRT supplies (military) conductivity improvers for gas oil, diesel and military jet fuels.

Corrosion inhibitors

Corrosion inhibitors lessen the rate of corrosion for metals and alloys. The corrosion inhibitor forms a passivation layer, which stops corrosive substances in the fuel from coming in contact with metal and repels water. The use of oxygenates in fuels has increased the demand for corrosion inhibitors. WRT offers corrosion inhibitors for crude oil, gasoline (components) and jet fuel.


Dehazers are surfactants which boost the coalescence of small water droplets suspended within the fuel, which decreases the settling time and increases water separation. WRT supplies dehazers to rid of the haziness from gas oil and diesel fuels.


Demulsifiers separate water, sediments and salt from crude and fuel oil.


WRT can supply red, blue and orange dyes which can be used to dye gas oil, diesel and gasoline.

Icing inhibitors

Jet fuel can hold a small amount of dissolved water that does not appear in droplet form. As an aircraft gains altitude, the temperature drops and the jet fuel’s capacity to hold water is diminished. Dissolved water can separate out, leading to a serious problem if it freezes in fuel lines or filters, blocking the flow of fuel and shutting down an engine. Icing inhibitors prevent the formation of ice in fuel lines.

H2S scavengers

H2S can naturally occur in crude oil and can be produced in refinery processes. WRT has a variety of different H2S scavenging technologies to treat both crude oil and refined products. WRT’s H2S scavengers eliminate the very toxic and pungent H2S from all oil streams.

Lubricity improvers

Low-sulphur diesel fuels have become an environmental necessity because of concerns surrounding the emissions of diesel engines. However, the reduction in the sulphur and aromatics content of diesel fuels has lead to lubricity problems. Low-sulphur diesel fuels have been shown to increase the wear and tear of all kinds of equipment. Lubricity improvers are able to restore the lubricity to the required performance level by creating a fine layer over a metal surface, so that direct metal-to-metal contact is avoided.

WRT supplies lubricity improvers to increase the lubricity of gas oil and diesel.


WRT markers are suitable for gas oil, diesel and gasoline applications.

Mercaptan scavengers

Mercaptans can cause an array of problems ranging from malodours to metal corrosion. Due to the volatility of mercaptans, they tend to evolve into vapour spaces, where their offensive odours generate problems in and around storage areas as well as throughout pipelines and shipping systems used for transportation.

WRT additives remove mercaptans from all oil streams.

Pour point depressants

Pour point depressants inhibit the deposition of paraffin wax in crude and fuel oils to allow the fuel to flow at lower temperatures. WRT’s pour point depressants improve the cold-flow properties of crude oil and fuel oil.

RON/MON boosters

Octane measures the fuel’s ability to resist knock which is caused by self-ignition of the fuel. WRT’s variety of RON/MON boosters improve the fuel’s resistance to self-ignition.

WRT stock RON/MON boosters (components) to improve the octane number of gasoline components.
