WVT: formulator of ash reduction solutions for waste oil streams

{ 30 januari, 2020 }

In the effort to minimise pollution of the oceans and waterways every ship must collect residues and oily mixtures generated during its ocean travels and discharge them to so-called port reception facilities, as indicated in the Marpol 73/78 protocol. These PRC facilities will recycle and regenerate the waste oil into second hand combustion fuels.

During this recycling process, the focus is on reducing the water and ash content in the waste oil. This is important because if the limitations for ash and organic chloride concentration are exceeded, the oil is less attractive for use as a fuel. WVT Industries responds with solutions that reduce effectively both ash content and organic chloride concentration.

Re-use of waste oil and lubricants

As crude oil and clean lubricants are becoming less available, efforts are being made to re-use waste oil and used lubricants as a second generation fuel.

During application, and especially after cleaning actions, oil and lubricants become polluted with water, heavy metals and halogens. If they remain untreated, these polluted flows will not only have a detrimental impact on the lifetime of the burner, but will also result in pollutants in the flue gases of the burner.

This is where WVT steps in. Instead of disposing of these flows as hazardous waste, they are treated to reduce both water and ash content, and allow re-use as a combustion fuel.

As the regulations regarding air-quality during industrial fuel oil burning are becoming more stringent, the need for low ash, high quality fuel oils becomes ever greater. This creates economic opportunities for the marketing of recycled oil.

Practical testing

As the composition of different flows of waste oil may vary, it is paramount to test for the most effective treatment that results in the lowest residual concentration for water, ash and halogens.

This is why WVT Industries has not only developed a range of treatment products, but also invested in laboratory solutions in order to be able to vary in both the use of products as in treatment conditions.

Examples of test results


In the first example a waste oil from the marine sector has been tested. Analysis made on the sample indicated increased concentrations of ash and more in detail potassium, calcium, aluminium and silica.

The test results can be seen as follows:

The test results indicate that a pure demulsifier (treatment 1) is insufficient for the reduction of the ashes, but a combination of an ash reduction aid and a demulsifier has resulted in waste concentrations low enough to comply with the limitations for both the total ash, as well as for the different metal components separately.


In this sample the total chloride concentration exceeded by far the maximum allowed limitation. Presence of chlorides in the waste oil in the burner will be converted into hydrochloric acid, with a strong corrosive impact on the installation.

In the above graph it can be seen that the first treatment has an impact on the inorganic chloride, but almost no effect on the organic chloride concentration. A different product (treatment 2) not only has a good effect on the organic chloride concentration, but the effects on the inorganic chlorides are even better than treatment 1, resulting in a very good total chloride removal.

Available from WVT

At WVT Industries, we supply different demulsifiers, ash reduction aids and combination products. But we also offer support with lab tests and technical know-how, so that together we can streamline the recycling process of waste oils, achieving the lowest concentrations for water and ash.

An eco-friendly gas washing solution? Get to know Gaswash L-VOC Free!

{ 17 mei, 2019 }

There are certain gaseous components that may pollute your liquid or vapour stream. At this point the solution loses its effect, and environmental issues may arise. However, it is possible to remove these contaminants from your process stream. By using a gas washing technique, with the appropriate absorbing fluid, the process stream regains its initial power and performance.

Eco-friendly Gaswash L-VOC Free

One of the products added to improve the contaminant removal in the gas washing process is Gaswash L VOC Free. Our unique absorbing fluid removes non-polar organic matter, making it the perfect choice for capturing gaseous substances. At the same time, the product is perfectly applicable to liquid components.

Gaswash L VOC Free is thus perfectly suited for filtering out non-polar gases using gas washing installations. Since the gases are retained and Gaswash L VOC Free itself does not contain any VOC, the outflow following the gas washing process will no longer contain any non-polar VOC components.

The advantages of Gaswash L-VOC Free

Gaswash L-VOC Free is an excellent product when it comes to washing gasstream, eliminating hazardous non-polar contaminants. In addition, the product has some competitive advantages compared to other available products:

  • The product is a VOC-free formulation and has no hazard classification according to CLP. It is therefore safe to use, both for the user and the environment.
  • Gaswash L-VOC Free has a very high flash point (120 °C), which means there is only a small risk of fire when using this product.
  • The product does not release vapours or gases, so using a respiratory mask is not required.
  • Since Gaswash L-VOC Free is water-insoluble, it will not affect the function of an oil/water separator.

Gas washing with Gaswash L-VOC free: how does it work?

Gas washing does require some technical knowledge to determine the right scrubber and the most suitable absorption liquid.

There are a few things to keep in mind during this process:

  • Every pollution is a unique one. It is therefore crucial to thoroughly examine the polluted liquid in the first place. The absorption capacity and flow rate must be adjusted as such.
  • The contaminated liquid or vapour stream is guided through the gas scrubber. We recommend reducing the flow through the gas scrubber to a minimum. This maximises the contact time and will improve the elimination rate of the contaminants from the gas stream.
  • The absorption of gases can be perfectly monitored by measuring the VOC emissions after the washing process. This last check also gives a good indication of the solution’s saturation and when you need to replace it.
  • As long as the VOC remains low, your gas washing solution (such as our eco-friendly Gaswash L VOC Free) still has sufficient absorption capacity. If the VOC increases, the liquid becomes saturated and you need to replace it. This way the liquid can be used to its fullest extent and an early replacement can be avoided.
