Thermal Cracking of Petroleum. Chapter. Petroleum (also called crude oil) is a naturally occurring mixture of hydrocarbons, generally in a liquid state, which may also include compounds of sulfur nitrogen oxygen metals and other elements (ASTM, 2002). Thermal cracking is an extraction process in which hydrocarbons such as crude oil are heated to a high temperature to break the molecular bonds. cracking Related words Visbreaking is thermal cracking when the vacuum residue is less viscous and it can then be used to produce valuable products. Thermal cracking can be thought of as a “chopping up” of the carbon atom backbone of the oil molecules. Because an oil’s viscosity is directly related to the average size (carbon chain length) of the molecules, extreme thermal cracking can result in a drop in viscosity, which can be an effective early warning tool. In a thermal cracking process, the molecular bonds of the liquid are broken to the lighter ones. Recently due to the availability of more heavy oils, the process interest was to yield light and

Thermal cracking produces shorter straight chain alkanes from longer straight chains found in gas oils or other crude oil fractions. Free radicals (reactive species with unpaired electrons, but no electronic charge) are the active species that govern thermal cracking reactions.

Thermal cracking and catalytic cracking are two major processes used in petroleum refineries in order to obtain useful products out of crude oil distillates. Both techniques have advantages as well as drawbacks. Thermal cracking remains important, for example in producing naphtha, gas oil, and coke, and more sophisticated forms of thermal cracking have been developed for various purposes. These include visbreaking , steam cracking , and coking . Thermal - you heat large hydrocarbons at high temperatures (sometimes high pressures as well) until they break apart. steam - high temperature steam (1500 degrees Fahrenheit / 816 degrees Celsius) is used to break ethane, butane and naptha into ethylene and benzene, which are used to manufacture chemicals. The first thermal cracking process was developed around 1913. Distillate fuels and heavy oils were heated under pressure in large drums until they cracked into smaller molecules with better antiknock characteristics. However, this method produced large amounts of solid, unwanted coke. Thermal cracking causes a reduction in viscosity, flash point, fire point and auto-ignition temperature. It is not uncommon to discover carbon varnish on the heat transfer surfaces. Typically, this is from a further disintegration of the Carbon-Hydrogen bond.

Thermal cracking is one of the most important procedural steps in the refinery for converting crude oil into the lighter and valuable petroleum products such as gasoline (or petrol), diesel fuel, residual heavy oil, coke, and many gases such as C1, C2, C3, C4 (methane, ethane, propane, butane). Thermal cracking causes a reduction in viscosity, flash point, fire point and auto-ignition temperature. It is not uncommon to discover carbon varnish on the heat transfer surfaces. Typically, this is from a further disintegration of the Carbon-Hydrogen bond. Thermal cracking is the cracking of heavy residues under severe thermal conditions. The liquid products of this process are highly olefinic, aromatic and have high sulphur content. The liquid products of this process are highly olefinic, aromatic and have high sulphur content.
