  2. Kerosene - Wikipedia

    en.wikipedia.org/wiki/Kerosene

    The ASTM recognizes two grades of kerosene: 1-K (less than 0.04% sulfur by weight) and 2-K (0.3% sulfur by weight). [16] Grade 1-K kerosene burns cleaner with fewer deposits, fewer toxins, and less frequent maintenance than 2-K, and is the preferred grade for indoor heaters and stoves. [17] In the United Kingdom, two grades of heating oil are ...

    Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.

  4. Edeleanu process - Wikipedia

    en.wikipedia.org/wiki/Edeleanu_process

    The Edeleanu process is a type of extraction process in the petroleum refining industry, whereby liquid sulfur dioxide is used to extract aromatics from kerosene. Liquid SO 2 selectively dissolves the aromatics leaving behind the low aromatic content kerosene as the finished product. [1] It is named after the Romanian chemist Lazăr Edeleanu.

    In the design shown in Figure 1, the coke has only been partially combusted to CO 2. The combustion flue gas (containing CO and CO 2 ) at 715 °C and at a pressure of 2.41 bar is routed through a secondary catalyst separator containing swirl tubes designed to remove 70 to 90 percent of the particulates in the flue gas leaving the regenerator ...

    en.wikipedia.org/wiki/Oil_refinery

    The final step in gasoline production is the blending of fuels with different octane ratings, vapor pressures, and other properties to meet product specifications. Another method for reprocessing and upgrading these intermediate products (residual oils) uses a devolatilization process to separate usable oil from the waste asphaltene material ...

  7. Primus stove - Wikipedia

    en.wikipedia.org/wiki/Primus_stove

    The No. 1 stove weighs about 2.5 pounds (1.1 kg), and measures about 8.5 inches (220 mm) high with an overall diameter of just under 7 inches (180 mm). The tank, about 3.5 inches (90 mm) high, holds a little over 2 imperial pints (1.1 L) of kerosene and will burn for about four hours on a full tank.

  8. Petroleum industry - Wikipedia

    en.wikipedia.org/wiki/Petroleum_industry

    The world consumes 36 billion barrels (5.8 km 3) of oil per year, [1] with developed nations being the largest consumers. The United States consumed 18% of the oil produced in 2015. [2] The production, distribution, refining, and retailing of petroleum taken as a whole represents the world's largest industry in terms of dollar value.

  9. Atmospheric distillation of crude oil - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_distillation...

    The pressure at the top is maintained at 1.21.5 atm [2] so that the distillation can be carried out at close to atmospheric pressure, and therefore it is known as the atmospheric distillation column. [3] The vapors from the top of the column are a mixture of hydrocarbon gases and naphtha, at a temperature of 120 °C–130 °C.
