Port reception facilities

According to Annex II of the MARPOL Convention, slobs from oil tanks or oil-contaminated water must be treated for further processing. Port reception facilities must recycle these slobs as quickly and efficiently as possible so that seagoing vessels do not lose time. To meet the needs of the shipping industry, WVT Industries has developed specific demulsifiers in order to treat each sludge (oil/water mixture) optimally.

Oil-water separation solution

In 'Q03', WVT Industries has developed a highly effective and environmentally friendly demulsifier, specially designed for the shipping industry.

Q03 significantly optimises oil-water separation and allows processing costs to be greatly reduced: Demulsifier Q03 replaces the use of costly centrifuge applications. It reduces the treatment time to less than 12 hours, allowing larger volumes to be treated in a shorter time.

As standard, the water-in-oil emulsion is heated to about 90°C before a demulsifier is added. Demulsifier Q03, however, is added at 60°C, resulting in drastic energy savings.

Slobs within the marine industry are a water-in-oil emulsion or oil-in-water emulsion whose stability is highly dependent on the water content.By adding Demulsifier Q03 to this in combination with an elevated temperature, the water - in - oil content is drastically reduced and this in most scenarios to max. 1% water.This implies a higher calorific fuel value of the processed oil with an increased combustion quality and sales value.

Typically, the recommended Demulsifier Q03 dosage varies between 1500 and 300 ppm to the total amount of the oil-in-water emulsion or water-in-oil emulsion.

In order to determine the correct and most appropriate demulsifier, WVT Industries analyses these emulsions ( slobs ) in its own laboratory and then provides the appropriate recommendations through a comprehensive analysis so that each stream can be treated in the most cost-effective manner.
