Key term 11

Uses a reactor to make one large molecule out of two small molecules.

  Used a reactor filled with catalyst to cause a chemical reaction that produces the desired products.

 Uses a fixed-bed catalyst to separate smaller hydrocarbons from large ones.

  A series of stills arranges so the vapor and liquid products from each tray flow counter currently to each other.

 Device in which the fixed medium remains in place as raw materials pass over it.

 A process that uses a reactor to split large gas oil molecules into smaller, more useful ones.

A process that uses a reactor to scrape the bottom of the barrel and squeeze light products out of the residue.

Uses a multistage reactor system to boost yields of gasoline from crude oil.

 Sweetens products by removing sulfur.

 A device used to convert raw materials into useful products through chemicals reactions. It combines raw materials, heat, pressure, and catalysts in the right proportions to initiate reactions and form products.

 A heat exchanger used to maintain the heat balance on a distillation tower.
