But because fractional distillation only produces about 20% gasoline from the crude, petroleum engineers get techy by using some sophisticated combinations of physic and chemistry in a process called “cracking”. Cracking is the process of breaking apart longer hydrocarbon molecular chains into smaller pieces. The process breaks or cracks the heavier, higher boiling-point petroleum fractions into more valuable products such as gasoline and diesel fuel. The process, which essentially is cracking in reverse, takes place in a series of large, horizontal vessels and tall, skinny towers. Reforming uses heat, moderate pressure, and catalysts to turn naphtha, a light, relatively low-value fraction, into high-octane gasoline components. Crude oil would be an ideal feedstock for directly producing olefins and aromatics. Then, direct steam cracking of crude oil has to deal with coking issues, which can be tackled by separating the heavy fraction or using solid heat carriers to retain coke , , . According to the IHS report, the ExxonMobil process completely bypasses the refinery and feeds crude oil to the cracking furnaces. These have each been modified to include a flash pot between the convective and radiant sections of the furnaces. Next, the crude oil is pre-heated and then flashed, IHS said, Refinery Processes Distilling. Much like a simple still, in a distilling column, liquid is heated to a vapor CRACKING. Because there is more demand for some distilled products like gasoline, Reforming. The process of reforming was developed to raise both the quality and volume TREATING. Crude oil is converted to gasoline through a process that includes refining and distilling the substance to remove impurities. Crude oil is separated into products like gasoline and kerosene in cracking towers at oil refineries. Coking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products and, as the name implies, produces petroleum coke—a coal-like material. Exports of petroleum coke accounted for about 19% of the nation's finished petroleum product exports through October 2012 with most going to China and other Asian countries.

Cracking takes large hydrocarbons and breaks them into smaller ones. This process reduces the viscosity of heavy weight oils and produces tar. coking  Steam cracking uses a higher temperature of over 800°C and no catalyst. The slideshow describes the process of catalytic cracking.

Cracking, in petroleum refining, the process by which heavy hydrocarbon molecules are broken up into lighter molecules by means of heat and usually pressure  The most valuable fractions for the chemical industry, and for producing petrol, are liquefied petroleum gas (LPG), naphtha, kerosine and gas oil. These are treated  29 May 2018 Cracking is a chemical process used in oil refineries. Cracking separates large hydrocarbon molecules in raw crude oil to create byproducts  Cracking takes large hydrocarbons and breaks them into smaller ones.

The slideshow describes the process of catalytic cracking. Thermal cracking is a process in which hydrocarbons present in crude oil are subject to high heat and temperature to break the molecular bonds and breaking   28 Oct 2019 Download Citation | Improvement of heavy crude oil via catalytic cracking process for refining into valuable blending stocks | In this study, it was 

It takes heavy oil and cracks it into gasoline and kerosene (jet fuel). After various hydrocarbons are cracked into smaller hydrocarbons, the products go through another fractional distillation column to separate them.

Crude oil is vapourised and fed into the bottom of the fractionating column. As the vapour rises up the column, the temperature falls. Fractions with different boiling points condense at different levels of the column and can be collected. Catalytic Cracking Processes Print Increasing demand for gasoline, along with the need to produce high-octane gasoline for increasingly more powerful spark ignition engines, led to the development and maturation of catalytic cracking processes just before and during World War II. Modern separation involves piping crude oil through hot furnaces. The resulting liquids and vapors are discharged into distillation units . All refineries have atmospheric distillation units, while more complex refineries may have vacuum distillation units . It takes heavy oil and cracks it into gasoline and kerosene (jet fuel). After various hydrocarbons are cracked into smaller hydrocarbons, the products go through another fractional distillation column to separate them. The first process is known as distillation. In this process, crude oil is heated and fed into a distillation column. A schematic of the distillation column is shown in Figure 2.2. As the temperature of the crude oil in the distillation column rises, the crude oil separates itself into different components, In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon -carbon bonds in the precursors.

Cracking is a chemical process used in oil refineries. Cracking separates large hydrocarbon molecules in raw crude oil to create byproducts such as heating oil, gasoline, liquefied petroleum gas, diesel fuel, jet fuel and other petroleum distillates.
