One of these is thermal cracking which is used on crude oil. The American chemist, William Burton, is usually credited with being the inventor of the thermal cracking process. The truth is that many others of different nationalities have been involved as the process has been developed and improved over time. 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. Visbreaking units typically convert about 15 percent of the feedstock to naphtha and diesel oils and produce a lower-viscosity residual fuel. Thermal cracking units provide more severe processing and often convert as much as 50 to 60 percent of the incoming feed to naphtha and light diesel oils. 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 In thermal cracking, high temperatures (typically in the range of 450°C to 750°C) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones. Thermal cracking gives mixtures of products containing high proportions of hydrocarbons with double bonds - alkenes. 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 . Visbreaking, a mild form of thermal cracking, significantly lowers the viscosity of heavy crude-oil residue without affecting the boiling point range. Residual from the atmospheric distillation tower is heated (800°-950° F) at atmospheric pressure and mildly cracked in a heater.

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

Crude Oil Cracking & Environmental Concerns Would you believe that petroleum engineers can use physics and chemistry to break apart various hydrocarbon chain-like molcules into gasoline-size molecules? It's kinda like rearranging Legos with each piece representing a CH4 (methane) molecule. Abstract.
