Hydrocarbons Produced
The following substances (lightest to heaviest or from the top of the tower to the bottom) are produced: off gas, straight run gasoline (composed of molecules with 5 to 10 carbons in length), kerosene distillate (with molecules of 11 to 12 carbons in length), light gas oil (13 to 17 carbons), and heavy gas oil (18 to 25 carbons), used for lubricating oils. Collecting trays located at intervals up the tower collect products according to their density, with the least dense products such as off gas and straight run gasoline being trapped and siphoned off closer to the top of the fractionating tower, with the heavier materials such as the gas oils being taken off closer to the tower's bottom. These products can then be shipped. |
