ABSTRACT:
An improved method of simultaneously removing high-boiling materials and a volatile dissolved substance, such as oxygen, from a hydrocarbon stream as is performed in feed preparation columns. About 25 to 75 percent of the feed stream is vaporized in a flash zone, and the vapor stream from the flash zone is combined with the overhead vapor stream of a fractionation column. The liquid remaining after the flash operation is passed into a lower intermediate point of the fractionation column. The high-boiling materials are removed at the bottom of the column, and the product stream is removed from the fractionation column at a higher intermediate point.
