24th May 2007Dear Dr. Vis, i would like to seek your profesional points of view in the process of blending these two fuel, High Speed Diesel or MGO with IFO180, both specs are as per attached, what is the maximum ratio of blending if it's for general vehicle like lorry and trucks, and for diesel-engine vessels? i would like to ask Dr. Vis, what is the possibble bleaching agents that can be used to reduce the Colour of these blended fuel if the ratio is 70% of HSD and 30% of IFO180 below/maintain 2.5?
Thank You So Much!
Best Regards!

IP: x.x.186.141Sorry Dr. Vis, actually i would like to know what is the chemical or bleaching agent that can be used to reduce the dark color as a result of blending the thick dark-colored IFO with transparent orange-colored MGO, so that the end color will much like normal MGO, as Dr can see the MGO spec as per attached, there is a column "Colour ( ASTM ) - 2.5 D 1500 / D 6045". Beside that, i also would like to know if there is any chemical or agent that can be used to reduce the sulfur content of these two IFO180 and MGO blending? Thanks again - Dr. Ram Vis

IP: x.x.203.241I do not think that there is any additive which can reduce the dark color which comes from the carbon content of the fuel oil.
I can certainly confirm that there is no chemical or agent that can reduce the sulphur content in IFO 180 or MGO. The process of blending will bring down the sulphur since MGO has relatively low sulphur. - Max CSC

IP: x.x.90.21Dear Dr. Vis, may i know what is the possible ratio of blending IFO 180 and MGO as if it would be used for heavy trucks or lorry? is 20% of IFO and 80% of MGO possible and what is the sulphur content of the blending? TQSM - Francis Fajardo

IP: x.x.109.111max, you cannot bleand this two fuels and use it as a fuel to run trucks or lorry. you can use this blend as a special fuel oil for use in certain ship engines and large low revolution engines such as in use in the power generation. - Hanni Doctor

IP: x.x.142.2We control colour and sulfur in IFO 180 as well as in IFO 380. We use COQI technology which is developed to control impurities in Crude oil or any fraction of crude oil. Using Sulfur control technology we control sulfur in IFO 180 / 380 in 0.5% to 2% range. - in other counries these bleanding is iilegal, why? because they are very strict with the sulfur content. here in asia, our regulations are lower compared with other countries. here's an example ;

The Diesel Wars
Picture the scene - An oil distributor driver arrives at the laboratory reception area clutching cans marked with the official stamp of the Customs and Excise. His story is familiar. Stopped at a checkpoint in Donegal, as the Customs officials carried out their roadside marker tests. The clear colour in the test tube indicated a negative for marker dye. However, instead of waving him on, they seized the truck and drove it into Letterkenny for further investigations. On the way home on the bus to Monaghan, the driver must have pondered on the events that led him to have his truck and 35,000 litres of diesel impounded by the Customs and Excise.
As it turned out, he had good reason to be worried, that's according to Martin Boylan B.Sc., M. Inst. Petroleum, Independent Laboratory Ltd. The sulphur content result was 800 ppm - the maximum sulphur level allowed for diesel in the Republic is 350 ppm, stated Martin. Marked gas oil has around 1500 ppm, so in the book of evidence for the Prosecution, the Customs can use simple calculations to present their version of what happened. The diesel was washed - that is, the dye was removed with acid, the residual acid was neutralised with alkaline sodium hydroxide, and the dye was undetectable. But it takes a technically sophisticated sulphur removing unit - usually only available at a refinery - to remove the sulphur down to levels that are legal. Therefore, when he goes to court, his case will be weak - the supply source having vanished, the bill of purchase worthless. He will be another knowing or unknowing victim of the official washed diesel war.
