“…Demetallization processes are valuable in their own right as metal recovery processes; a third of all vanadium produced by Russia stems from demetallization of heavy oil and 8% the world production of vanadium comes from oil feedstocks. Demetallization takes place in the electrostatic desalter at a refinery although this process is typically modified to deal with stable organometallics with electrolysis cells and polymeric sorbents being used to recover metals (Magomedov et al, 2015).…”

Industrial solid waste management encompasses a vital part of developed and developing countries strategies alike. It manages waste generated from vital industries and governs the hazardous waste generated as a major component of integrated waste management strategies. This article reviews the practices that govern the management approaches utilized in the developed world for industrial spent catalysts. It critically assesses the current situation of waste management within the developing world region focusing on the industrial waste component, in a novel attempt to crucially develop a strategy for a way forward based on best practices and future directions with major European industries. The review also draws parallels with European countries to compare their practices with those of the State of Kuwait, which rely solely on landfilling for the management of its industrial waste. Spent catalysts recovery methods are discussed at length covering conventional methods of valuable metals and chemicals recovery (e.g., hydrometallurgical, solid–liquid and liquid–liquid extraction) as well as biological recovery methods. A major gap exists within regulations that govern the practice of managing industrial waste in Kuwait, where it is essential to start regulating industries that generate spent catalysts in-view of encouraging the establishment of valorization industries for metal and chemical recovery. This will also create a sustainable practice within state borders, and can reduce the environmental impact of landfilling such waste in Kuwait.

“…An petroleum oil refinery is an industrial process where crude oil is processed into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, etc [56][57][58]. The first manufacture step of petroleum products is the separation of crude oil into the main fractions by atmospheric distillation.…”

“…Also, small amounts of nickel and vanadium in the charge stocks poison clay and synthetic catalysts. These metals in the heavy residue cannot be eliminated by simple chelation process since they exist as very stable [29,56,64,65]. The nickel and vanadium metals in the vacuum residue (VR) have eliminated by the combination of solvent separation process and chelation process [64,65].…”

It has been estimated that the Earth has nearly 1.688 trillion barrels of crude oil, which will last 53.3 years at current extraction rates. The organization of petroleum exporting countries (OPEC) group forecasted that the oil prices will not jump to triple-digit territory within a decade, but it can quickly increase as the political issue for reducing oil production appears. With the potential of serious shortage of conventional hydrocarbon resources, the heavy oil, one of unconventional hydrocarbon resources including oil sand and natural bitumen has attracted worldwide interest. The heavy oil contains heavy hydrocarbon compounds, commonly called as resins and asphaltenes, with long carbon chains more than sixty carbon atoms. The high content of heavier fraction corresponds with the high molecular weight, viscosity, and boiling point. Physicochemical properties of residues from vacuum distillation of conventional oil, referred to as vacuum residues (VR) were similar to those of heavy oil. For the development of heavy oil reserves, reducing the heavy oil viscosity is the most important. In this article, commercially employed aquathermolysis processes and their application to VR upgrading are discussed. VR contains transition metals such as Ni and V, but these metals should be eliminated in advance for further refining. Recent studies on demetallization technologies for VR are also reviewed.

“…1 Hydrodemetallization, which is the first step of hydrotreating, is seriously limited by the poor quality of heavy oil, especially the high concentrations of vanadium (V) and nickel (Ni). [2][3][4] V and Ni contained in heavy oil are usually in the form of porphyrin, aetioporphyrin, or non-porphyrin complexes. 5 Although metal removal can be achieved by hydrodemetallization, the catalyst will be irreversibly deactivated because of the deposition of V and Ni on the catalyst surface.…”

Demetallization of heavy oil through pyrolysis: A reaction kinetics analysis

et al. 2020

View full text Add to dashboard Cite

By tracking the transfer of vanadium and nickel in pyrolysis products, a seven‐lump reaction kinetic model for pyrolysis‐based demetallization of heavy oil was established. During pyrolysis, the demetallization of heavy oil is achieved by condensing metal‐rich resins and asphaltenes to coke. The condensation of oil components originally contained in heavy oil differs greatly in reaction behavior, having the activation energy between 167 and 361 kJ/mol. As the pyrolysis progresses, the newly formed heavy components show a condensation behavior close to that of the light components. Limited by high activation energy and low initial fraction, the condensation of asphaltenes to coke and the resulting removal of metals contained in asphaltenes are hindered. Meanwhile, the condensation of light components has a major contribution to coke formation. An increase in reaction temperature accelerates the demetallization, but hardly changes the yield and component distribution of liquid products at the same metal removal rate.
