In the diagram, atmospheric distillation used to separate lighter petrochemical and fuel fractions from the non-boiling component at the bottom, known as an atmospheric residue. We expect refinery utilization to average 96% in June, 94% in July, and 96% in August. In the petroleum refining process, the Crude Unit is the initial stage of distillation of the crude oil into useable fractions, either as end products or feed to downstream units. The residue from the atmospheric tower contains heavy hydrocarbons having boiling points >450oC. The unit preheats, de-salts, and separates crude oil into naphtha, No. The inside of your distillation tower should be lined with dozens of distillation trays, each with many small holes. Crude stills are the oldest means for processing oil. It is then desalted to remove inorganic salts. Because the simple distillation of crude oil produces amounts and types of products that are not consistent with those required by the marketplace, subsequent refinery processes change the product mix by altering the molecular structure of the hydrocarbons. This is accomplished by distilling at atmospheric pressure with steam stripping for improved cuts.
