What are Vacuum Tower Bottoms

Vacuum Tower Bottoms (VTB) are the left over bottom product of distillation, which can be processed in cokers and used for upgrading into gasoline, diesel and gas oil.

Crude oil separation is performed in a series of distillation towers, with the bottom product from each tower feeding the next from the top down. The resulting products from the distillation tower process range from gases at the top to very heavy, viscous liquids at the bottom. In all cases, these “unfinished” product streams require further processing to become useful products.

Uses for Vacuum Tower Bottoms

Vacuum Tower Bottoms or “resid” are the heaviest material in the refinery tower. If allowed to cool to room temperature, Vacuum Tower Bottoms would become a solid. Some Vacuum Tower Bottom product is actually sold to the paving asphalt market as a blend component. The Delayed Coker is used to convert VTB material into more valuable products by using high temperature to break the hydrocarbon chains. Vacuum Tower Bottoms are included in the refining process to make off road fuels, off spec fuels, biodiesel fuels ASTM B100 & B99, specialty fuels, and blending stocks while improving profitability.
