stripping tray

The user's query contains the term "stripping tray," which is a component used in petroleum refining. The search results provide information about petroleum refining processes, including fractional distillation and the use of stripping trays.

Petroleum refining primarily involves separating crude oil into various hydrocarbon fractions. Fractional distillation is the main process, using tall columns with trays to separate components based on their boiling points. Crude oil is heated and vaporized, then rises through the column. Lighter components condense at higher levels, while heavier components remain liquid at lower levels.

Stripping trays are located in the lower part of the distillation column. Their function is to remove any remaining light constituents from the liquid residue before it exits the bottom of the column. Steam is often injected into the bottom to aid this separation. This process helps to maximize the recovery of valuable products from the crude oil.
