As the bunker industry now faces significant increases in 0.5% compliant blended fuel oils, refiners must prepare for the challenges that differing fuel oil compositions bring. As these fuels will vary significantly in their characteristics and qualities, challenges such as instability/ incompatibility and increased pour point become concerns for marine fuel customers.
- As there is no universally accepted refining method for 0.5% sulphur fuel, there will be a variety of fuel qualities being offered. The issue of incompatibility and instability may immediately occur when different fuel streams mingle.
- Blended products in particular may not be reliably stable and could be incompatible with other fuels.
- Bottom sludge formation could occur in a vessel’s fuel tank due to this incompatibility risking blocked filters or even total engine failure
- Differences in fuel characteristics brought about by blending different streams can have a significant effect on the cold flow behavior of fuel.
- Increased amounts of paraffins in typical fuel oil compositions can lead to wax drop out of long chain paraffins at lower temperatures causing potential filter blockages.
- Depending on the cut point of the fuel, the blends may also show an increased pour point that does not comply with the requirements of ISO 8217.
Clariant Refinery Services has the marine fuel experts, marine fuel compatibility enhancer and PPD additive solutions, and technical capabilities to help minimize these IMO 2020 challenges.

MARINE FUEL COMPATIBILITY ENHANCER FOR LOW SULPHUR FUEL OIL THAT DELIVERS RELIABLE AND COMPLIANT PERFORMANCE
This IMO 2020 tailormade solution has specifically been designed to improve the stability of low sulphur fuel oil (LSFO) and support the compatibility of fuel oil mixtures by dispersing asphaltenes and other fuel oil components.
Low Sulphur fuel oils streams can be based on aliphatic hydrocarbons with a paraffinic character or they consist of heavier aromatic components including asphaltenes. Comingling of those streams can lead to stability problems and the precipitation of asphaltenes and other fuel oil components. Neither shipowners nor fuel suppliers will know when or where different LSFO qualities have been mixed. Therefore, refueling different LSFO qualities from different regions and/or suppliers bears the risk of complaints due to fuel incompatibilities.
DISPERSOGEN® 2020, Clariant’s innovative marine fuel compatibility enhancer solution, will ensure that global refiners can meet new regulation standards with fuel oil blends that will remain stable and compatible.
Clariant’s DISPERSOGEN® 2020 can be used as a preventative measure to allow LSFO blending across all regions, which will help global refiners meet new regulation standards with fuel oil blends that will remain stable and compatible.
- The graph shows the average percentage transmission of light (%) versus height (mm) of the test tube after 15 minutes.
- The untreated blank low sulphur fuel oil (LSFO) shows an increasing transmission over the length of the tube reflecting precipitation of insoluble matter.
- DISPERSOGEN® 2020 shows a constant transmission throughout the test tube indicating a homogenous distribution of particles and a low separability number.
- The asphaltene dispersion was measured according to ASTM D 7061 using a turbi scan MA 2000.
Cold flow behavior of marine diesel and LSFO are significantly impacted by their composition. Cut points of the marine gas oil as well as heavy refinery stream as part the LSFO may show an increased pour point that does not comply with ISO 8217 requirements. Clariant Refinery Services’ DODIFLOW product line offers pour point depressant solutions for LSFO and Marine Diesel.
SPECIALIZED POUR POINT DEPRESSANT DESIGNED TO IMPROVE COLD FLOW PROPERTIES OF 0.5% SULPHUR FUEL OILS
Clariant DODIFLOW®-type products were tested to lower the pour point of the LSFO to the specification of 30°C (86°F).
- Considering the high blank pour point of the LSFO sample, DODIFLOW® 8421 shows an excellent response behavior and a very low dose rate to achieve the target.
- For the provided test results LSFO and PPD had a temperature of 50°C (122°F).
- Using 200 ppm of DODIFLOW® 8421, the pour point of VLSFO was reduced to 27°C (81°F).
- Increasing the dose rate continues to improve the PPD-response up to 12°C (54°F) at a dose rate of 1000 ppm.
PREMIUM FUEL ADDITIVE POUR POINT DEPRESSANT TO IMPROVE THE COLD FLOW PROPERTIES OF LOW SULPHUR MARINE FUEL DISTILLATES
Clariant Marine Diesel PPD DODIFLOW® 6087 was used to treat DMA marine fuel to the required specification.
- The used DMA quality had a blank pour point of 15°C.
- The summer and winter specification, which are required by ISO 8217, are easily met with dose rates of 65 and 75 ppm, respectively.
- The graph shows that increasing the dose rate leads to further improvement of the pour point, which leaves additional options for the refiner to blend heavier components into the marine diesel.
