Fluid coking unit means a refinery process unit in which high molecular weight petroleum derivatives are thermally cracked and petroleum coke is continuously produced in a fluidized bed system. The fluid coking unit includes the coking reactor, the coking burner, and equipment for controlling air pollutant emissions and for heat recovery on the fluid coking burner exhaust vent.
2017/8/12· Polycyclic aromatic hydrocarbons (PAHs) are major organic pollutants in the environment, which are toxic to humans and biota, given their carcinogenic, mutagenic and teratogenic nature. In this chapter, we carried out an overview of the sources and toxicity of PAHs, their common analytical methods of determination in the water and sediment samples, and also their global trend of distribution
Systems and methods are provided for producing high quality synthesis gas from a fluidized coking system that includes an integrated gasifier. Additionally or alternately, systems and methods are provided for integrating a fluidized coking process, a coke
The kinematic viscosity data are used to evaluate the mean molecular weight of the petroleum oils. A set of equations is used that fits the data provided by the ASTM standard D 2502-04. (This standard is commonly used in the petroleum industry to calculate the
Our petroleum cryoscopes are used globally at well sites and central labs to determine the molecular weight of petroleum products. From characterization of cracking fractions to salinity testing, these instruments are used by major oil companies to identify and QC their products.
A coker or coker unit is an oil refinery processing unit that converts the residual oil from the vacuum distillation column into low molecular weight hydrocarbon gases, naphtha, light and heavy gas oils, and petroleum coke.The process thermally cracks the long chain hydrocarbon molecules in the residual oil feed into shorter chain molecules leaving behind the excess carbon in the form of
Maltenes and Asphaltenes of Petroleum Vacuum Residues 95 Fainberg et al. (1996) have modified the ASTM D4124 (Drews, 1989) method by carrying out extraction in soxhiet apparatus, by heptane. By using pentane, asphaltenes precipitate along with polar

Petroleum products are used to produce synthetic fibers such as nylon, orlon, and dacron, and other polymers such as polystyrene, polyethylene and synthetic rubber. They also serve as raw materials in the production of refrigerants, aerosols, antifreeze, detergents, dyes, adhesives, alcohols, explosives, weed killers, insecticides, and insect repellents.
