Petroleum products are supplies derived from crude oil (petroleum) as it’s processed in oil refineries. Unlike petrochemicals, which are a group of properly-defined usually pure chemical compounds, petroleum products are advanced mixtures. Nearly all of petroleum is converted to petroleum products, which incorporates a number of classes of fuels.
In line with the composition of the crude oil and depending on the demands of the market, refineries can produce completely different shares of petroleum products. The largest share of oil merchandise is used as “energy carriers”, i.e. numerous grades of fuel oil and gasoline. These fuels include or will be blended to offer gasoline, jet fuel, diesel gas, heating oil, and heavier gas oils. Heavier (much less volatile) fractions will also be used to supply asphalt, tar, paraffin wax, lubricating and different heavy oils. Refineries additionally produce other chemicals, a few of which are used in chemical processes to produce plastics and different helpful supplies. Since petroleum typically incorporates a few p.c sulfur-containing molecules, elemental sulfur can be usually produced as a petroleum product. Carbon, in the type of petroleum coke, and hydrogen might even be produced as petroleum products. The hydrogen produced is usually used as an intermediate product for other oil refinery processes equivalent to hydrocracking and hydrodesulfurization.
