Bottom materials Explanation: Productos de fondo Because the residuum tends to decompose at temperatures above 700°F (371°C), higher boiling oils such as lubricating oils must be distilled off in a separate vacuum fractionating tower. The greatly reduced pressure in the tower markedly lowers the boiling points of the desired oil compounds. *Bottom materials* from the vacuum tower are either used for asphalt or are further processed for other materials such as bright stocks. The fractions separated by crude distillation are referred to as "straight run" products. |

bottoms Explanation: or bottom product, if you want to keep the singular (I have seen it used), or vacuum bottoms / vacuum residue / vacuum resid Coker. Uses thermal processing to convert heavy refinery streams, such as vacuum bottoms, into light products such as naphtha and heating oil, while reducing the residual feedstock to solid petroleum coke. Coking. The thermal destruction of vacuum residue to provide lighter hydrocarbons, leaving behind a carbonaceous material called "coke." BOTTOMS Tower bottoms are residue remaining in a distillation unit after the highest boiling-point material to be distilled has been removed. Tank bottoms are the heavy materials that accumulate in the bottom of storage tanks, usually comprised of oil, water, and foreign matter.
