WebThe crude oil is first submitted to distillation under atmospheric or reduced pressure, in order to separate it in streams and produce petroleum fractions used in downstream refining processes. The refinery besides the distillation columns includes a variety of catalytic processes aiming at improving product yields and properties. WebCrude oil is a finite resource. It can be separated into its useful fractions by fractional distillation. Some fractions undergo cracking to help meet demand for the smaller …

WebFractional distillation separates a mixture into a number of different parts, called fractions. A fraction of crude oil is a mixture of chemicals in the crude oil that have similar boiling … WebReforming Reforming uses heat and pressure to convert unbranched fractions into cycloalkanes (e.g. cyclohexane) and arenes (e.g. benzene). These products are used in petrol and as a feedstock for a wide range of organic chemicals including many pharmaceuticals and dyes.After studying this section you should be able to: medication for cardiogenic shock

WebHundreds of different crude oils (usually identified by geographic origin) are processed, in greater or lesser volumes, in the world’s refineries. Each crude oil is unique and is a complex mixture of thousands of compounds. Most of the compounds in crude oil are hydrocarbons (organic compounds composed of carbon and hydrogen atoms). WebFigure 2.1: Simple flow diagram of an oil refinery. Crude oil is the first process, and it breaks the products down into LPG, straight-run gasoline, naphtha/kerosene/diesel, fuel oil, and resid. LPG is used in the alkylation process to add carbons; straight-run gasoline is processed in a catalytic reformer to change to a branched-chain alkane ...
