Demulsifier Q3 reduces treating and disposal costs of MARPOL oil

High calorific fuel in much less than twelve hours

Under the MARPOL Convention Annexe I, oil tank washing residues or oil-contaminated water must be treated before being discharged. WVT Industries, a Belgian market leader in industrial cleaning products and solvents, has developed a range of highly efficient demulsifiers for decantation processes. Its new Demulsifier Q3, separates water in oil and oil in water mixtures – quicker and at a lower cost than most competing products.

Under 1% water content

MARPOL oil is a water-in-oil emulsion with its stability depending on the water content, which is typically between 2.4% to 50.8%. Adding the new Demulsifier Q3 to MARPOL-oils significantly speeds up the decantation process and attains fuel with a water content of under 1%. In less than twelve hours, Demulsifier Q3 optimizes the calorific value of the recycled oil, and increases its resell value. To obtain optimum results, the water-in-oil emulsion is heated up to between 80 to 90°C before adding Demulsifier Q3.

Smaller dosages, better results

The optimum demulsifier dosage much depends on the specific nature of the oil waste. To determine the exact percentage needed, WVT Industries analyses waste samples in its own laboratory, and offers case-by-case recommendations. Typically, the recommended Demulsifier Q3-dosage varies between 1500 and 4000 ppm to the total amount of the oil-water emulsion. If higher dosages fail, the dosage should even be reduced: lower dosages of 3000 ppm usually improve the demulsification.

  1. Oil/water mixture without WVT Demulsifier
  2. Oil/water mixture with 2000ppm WVT Demulsifier
  3. Oil/water mixture With 3000ppm WVT Demulsifier
    With 3000 ppm Demulsifier Q3, a water content of under 1% is attained in less than 12 hours. The oil-water emulsion is heated up to 90°C before adding Demulsifier Q3.

Customer case: 0,42 % water content with 1500 ppm

After adding the WVT Demulsifier Q3 in dosages of 1500 ppm, the water content in the decanted fuel decreased to 0,42%. The water-in-oil emulsion was heated to 95 °C, before adding Demulsifier Q3. Without changing the variable of temperature, these results were obtained in under 12 hours. The customer reported to be happy with the first obtained results, and will continue to optimize all variables.

Reduced processing costs

Demulsifier Q3 significantly reduces processing costs. It replaces the use of cost burdening centrifuge applications. And it reduces the treatment time to less than twelve hours, so that larger volumes can be treated over a much shorter time period.

Sustainable solution

An organic liquid formulation of surfactants and dispersants, Demulsifier Q3 stays with the fuel – not with the water phase. The decanted water can be discharged without any detrimental impact on the marine environment. Combustible, non-abrasive, and non-ash-forming, Demulsifier Q3 improves the quality of fuel, while protecting the workers handling the product.

Odour neutraliser reduces downtime

Apart from demulsifiers, WVT Industries also produces water based liquid odour neutralisers to prevent odor nuisance or irritating fumes from escaping. Its O-Scent SCV cleans hydrocarbon based deposits and encapsulating hazardous gases, vapours and associated odours, including H2S, Benzene, Ammonia and Mercaptanes. The chemical formulation is 100% biodegradable. Combining all cleaning procedures in one chemical application, equipment downtime is significantly reduced.
