What is low Sulphur heavy stock?

What is low Sulphur heavy stock?

Low Sulphur Heavy Stock (LSHS) is a residual fuel processed from low Sulphur Crude. Due to its high pour point, it requires handling above ambient temperature, to maintain desired fluidity during storage and handling. LSHS is transported in insulated tank Lorries.

What is difference between HSD and LDO?

HSD is normally used in the engine which runs above 750rpm such as in buses, locomotives, trucks etc. And LDO is used in below 750 rpm engines. Generally it is used in steady engines or to burn in furnace.

What is HFO heavy fuel oil and diesel oil What is difference between the HFO and diesel oil?

The different blending ratios of marine diesel oil can be controlled directly by processes in the refinery or by blending ready-made marine fuels. Marine diesel is similar to diesel fuel, but has a higher density. Unlike heavy fuel oil (HFO), marine diesel oil does not have to be heated during storage.

What is very low sulfur fuel oil?

Heavy fuel oils are referred to as low sulfur fuel oil (LSFO) if their sulfur content is below 1%. Usually these are marine fuel types IFO 180 or IFO 380, which have been desulfurized. Until the end of 2014, ships could still travel through Emission Control Areas (ECAs) with this type of marine fuel.

What is the density of heavy fuel oil?

900 kg/m³
In the MARPOL Marine Convention of 1973, heavy fuel oil is defined either by a density of greater than 900 kg/m³ at 15°C or a kinematic viscosity of more than 180 mm²/s at 50°C. Heavy fuel oils have large percentages of heavy molecules such as long-chain hydrocarbons and aromatics with long-branched side chains.

How do I check my HSD quality?

The most accurate method of assessing the ignition quality of a diesel fuel is by measuring its cetane number in a test engine, the higher the cetane number the higher the ignition quality.

Is all gas station diesel ultra low sulfur?

Since December 1, 2010, all highway diesel fuel nationwide has been ULSD. Non-road diesel engine fuel moved to 500 ppm sulfur in 2007, and further to ULSD in 2010. Railroad locomotive and marine diesel fuel moved to 500 ppm sulfur in 2007, and changed to ULSD in 2012.

Is LDO and furnace oil same?

Light diesel oil (LDO) & furnace oil is the residual petroleum products and hydrocarbons. All the impurities and metal content of petroleum are concentrated in these products have many different industrial hitting applications .

How do I check my LDO quality?

What is ultra-low Sulphur fuel oil?

Ultra-low sulfur heating oil has a sulfur content of 15 ppm (parts per million) compared to traditional heating oil’s 4,000 ppm. Researchers at the Brookhaven National Laboratory have found that ULS heating oil significantly reduces emissions and improves heating system performance.
